Timeline: Tuesday, January 24, 2023

Times are as testified. Where the two sides read the same fact differently, both readings follow the fact.

Morning

The order of the killings, as asserted

Added 2026-09-06 from the Commonwealth's opening statement on day 1 [S305, ASR, unverified].

"One by one, she wrapped exercise bands around each one of the kids' necks and pulled until their little bodies were limp and lifeless. First Dawson, then Cora, and finally Callan."

The opening also asserted that in the basement "she separates Dawson from Cora and Callan."

PROS [S305, ASR, unverified]

This corpus records the mechanism and the causes of death but has never held a sequence. Whether the physical evidence established that order or whether it was argument is not resolved here, and no witness in this corpus has been recorded testifying to it. Carried to 08-open-questions.md.

The same opening put the timing theory: Patrick left at about 5:15 pm having seen Dawson eating chicken nuggets and green beans on the couch, and "that's when the clock starts." The Commonwealth argued she knew the distance to the restaurant and "knows exactly how much time she has." PROS [S305, ASR, unverified]

Afternoon

A note on the afternoon times. Boston 25 reported the laxative and menu searches at 4:46 pm and 4:43 pm [S7]. Oxygen's 4:02 and 4:13 are consistent with the 4:48 pm CVS call and the 5:10 pm order, so they are used here. The conflict is logged in 08-open-questions.md. Boston 25 also renders the laxative as MiraLAX; the pharmacy testimony and the purchase were Pedia-Lax, while the pediatrician had recommended MiraLAX that morning [S10][S77].

The errand, read two ways. The Commonwealth argued the errand was engineered: she "sent" Patrick out, then added the CVS stop, buying herself the window and the isolation. PROS [S6][S28] The defense argued the same sequence is what a devoted mother does on an ordinary evening, and that nothing about a takeout order and a pharmacy run shows intent. DEF [S6]

The device bracket, corrected 2026-09-05 against the Day 14 transcript [S210]. Ian Whiffin of Cellebrite, the Commonwealth's final witness and previously an expert in the Karen Read trial, gave the tightest timestamps in the case. Earlier passes of this file attributed a 5:38 pm trip up the stairs to the Apple Watch. That was wrong on both counts and is corrected here.

• Two devices, two stopping points. The watch stopped reporting heart rate at 5:23:52 pm. The iPhone kept logging to 5:38 pm. Both devices carry barometers and both can log flight climbs; the 5:03 pm and 5:33 pm climbs were logged by the phone and not by the watch.
• The climbs are ascents only. Whiffin explained that a logged "flight climb started" means the climb has already happened and the device has registered that it is about three meters higher. Descents are not logged. This data therefore cannot show when, or how many times, she went down to the basement, which is the gap Saathoff identified as unexplained.
• What it does bracket. An ascent at 5:33 pm, coinciding with Patrick's call from the CVS, and the end of recording at 5:38 pm. The 5:33 pm ascent, not a 5:38 pm one, is the event consistent with her leaving the lower level for the bedroom where she cut herself and went out the window.
• Her own heart-rate baseline. Roughly 50 to 122 across the day, averaging "high 80s, early 90s." The 57 bpm at 5:23:52 pm sits near the floor of her own range and far below her average. It is the only physiological measurement from inside the window, and no source records either side arguing what it implies. See 08-open-questions.md.
• The blackout. On cross Reddington established that after 5:38 pm "you don't know what was happening at 5:39," including who had possession of either device, and impeached Whiffin with his own June 2025 blog post on Apple Health accuracy and reliability. TEST Whiffin [S210][S212]

The dinner invitation. Christopher Clancy testified that he and his wife had been invited to dinner at the Clancy home that evening and declined because they already had plans, agreeing to meet that Friday instead. The Commonwealth elicited this. It is the single fact in the corpus that cuts hardest against a plan fixed on that specific evening, and no source here records either side arguing about it. TEST Christopher Clancy [S44]

The chicken nuggets conflict. Clancy told Dr. Saathoff she was making chicken nuggets when her husband called; Patrick testified the children were already eating them. Saathoff cited this among the inconsistencies in her accounts. PROS via TEST Saathoff [S17]

The killings

The Commonwealth's account: she took the children to the basement, separated them, wrapped exercise resistance bands around their necks and pulled them tight. PROS [S6]

Order of death, contested. The defense moved to strike the Commonwealth's timeline of the order in which the children died, arguing it implied she hated one child more than another and that no evidence made the order significant. DEF [S3] The ruling on that motion is not in this corpus, but the theory survived to closing, so it was not struck.

Sprague's closing gave the Commonwealth's actual argument, which was never about preference among the children but about tactical reasoning: "Cora and Dawson are older. If she had tried to strangle one in front of the other, they would have known this was bad. And they would have tried to intervene or run and hide, and she had very limited time. She didn't have time to try to find a child who ran off and hid. So taking Dawson first and moving him to a separate room; having Cora stay with Callan and having Dawson go in another room, that's rational. That makes sense. That's ordered thinking." PROS [S46]

So the Commonwealth's sequence was Dawson first, moved to the office; Cora and Callan together in the basement proper, which matches where Patrick found each of them. The argument was that the separation itself is evidence of intact reasoning under time pressure.

The medical examiners on mechanism

Added 2026-09-05 [S214][S217]. Dr. Barbara Olson performed the autopsies on Cora and Dawson; Dr. Renee Stonebridge, trained in neuropathology, examined the brains, spinal cords, eyes and dura of all three; Dr. Kimberly Springer gave Callan's cause of death on 08-06 [S10]. Earlier passes of this file gave Stonebridge and Olson jointly as the examiners for Cora and Dawson, which is imprecise.

Springer on Callan [S262], ASR grade. She performed the autopsy on 2023-01-29. Therapeutic equipment was still in place. On the neck: abrasions above the ruler line, and the abrasion visible on the front of the neck "continues along about 3 inches toward the right posterior," with petechiae around the eyes and face, which she gave as the indication of the mechanism of death.

No medical examiner described how the bands were fastened. Her full testimony [S256] covers the furrow, the petechiae, the force thresholds and the timings, and contains no account of a knot, a tie, or a ligature held by hand. The configuration question therefore survives her testimony and is not answerable from the medical examiner at all. See 08-open-questions.md.

Configuration, added 2026-09-05. Laposata testified the ligatures were "wrapped around the child's neck several times and then left there" [S248]. Left in place rather than held. That resolves the mechanics below in favour of concurrent rather than sequential pressure. See 08-open-questions.md for what is still missing, which is that neither autopsy pathologist was asked.

The arithmetic these figures create. This paragraph is this wiki's own reasoning, not testimony, and it rests on a five-minute figure that verification could not confirm [S218 verification]. At two to three minutes it loosens considerably. The conclusion it supports, that the ligatures were fastened, does not depend on it: that rests on Laposata [S248] and on Patrick's January 2023 statement [S247]. Olson's floor for death is about five minutes of sustained pressure per child. Patrick left about 5:15 pm and the iPhone stopped logging at 5:38 pm, an outer envelope of roughly 23 minutes, inside which Heilbrun put the killings at "18 minutes or so" [S110]. Three children at five minutes each, applied and held one after another, is fifteen minutes of pressure alone, before transport to the basement, before separating Dawson into the office, before the 5:33 pm ascent and the 5:34 pm call. Sequential manual pressure does not fit the window. Concurrent pressure from fastened, self-holding ligatures does. This is why the unresolved question of how the bands were fastened, in 08-open-questions.md, governs the whole reconstruction.

A second consequence, on the same reasoning. If the ligatures were producing death over minutes rather than instantly, then the 5:33 pm ascent and the 5:34 pm call fall inside the period during which at least one child was still dying, not after the killings were complete. The Commonwealth's 2023 framing, that she "even took a phone call after the murders" [S168], may misdescribe the sequence. Callan still had a faint pulse when Off. Josephine reached him after 6:09 pm [S18], and he survived on life support until 01-27 [S32]. Neither side is recorded arguing any of this.

What she could not account for. Saathoff testified she could not explain how the children got to the basement, or whether they struggled. He testified "Children are not puppets" and that children have a strong survival instinct, against her account of feeling like a puppet. PROS via TEST Saathoff [S17]

Her own injuries

She cut her wrists and her neck and went through a second-story window, sustaining a spinal injury that left her paralyzed from the waist down. STIP [S6][S12]

Physical evidence: a large puddle of blood in the middle of the second-floor bedroom, blood on the doorknob, the window open, a knife on scene, and red-brown stains on the window ledge and shingles. TEST Patrick Clancy, Sgt. McKelligan [S3][S7]

Crook, stain by stain [S236][S237]. Bloodstain pattern analysis looks at "specifically the size, shape, and the distribution of those stains." Stain C, on the mirror, elliptical, a drip stain or blood in flight, likely from someone near the mirror bleeding or holding a bloody object. The windowsill stain, irregular, classified as a transfer stain, from contact with something bloody. The nightstand carried drip stains plus linear transfer stains from the knife itself, and the pattern showed the knife had been moved.

Her concession on cross. Asked whether the blood could have come from someone "leaning on the window sill before going out, or hanging from it," Crook agreed that was possible [S237]. That cuts against the Commonwealth's 2023 bail-hearing framing that she "slid down" the side of the house and "did not jump" [S204].

A chain-of-custody stipulation was entered the same day covering blood evidence, the exercise bands, and DNA [S237].

The blood-spatter contradiction. Patrick testified the blood was "sprayed, almost like with a hose." TEST [S3] Sherri Crook of the Massachusetts State Police Crime Lab testified there is no evidence blood sprayed into the room at any point, and that the drips and puddles were "more suggestive of someone standing still and letting blood run down onto the floor than someone slashing an artery." PROS via TEST Crook [S33]

This is not a small discrepancy. It is the physical-evidence spine of the Commonwealth's argument that the self-inflicted injuries were less serious than they appeared and that she never truly intended to die, which in turn supports its motive theory that the children were removed as "protective factors" rather than as part of a genuine murder-suicide.

Read two ways. The defense treated the suicide attempt as "legitimate, dreadful, horrific," DEF [S8] and pointed to what actually happened to her: a shattered spine, permanent paralysis, intubation, and a cardiac arrest in the ICU that required a massive transfusion protocol to survive. DEF [S32][S41] The Commonwealth argued the blood pattern and the toxicology were both inconsistent with a genuine attempt and, in opening, framed the whole night as planned. PROS [S6][S25][S33] See 06-medication-psychiatric.md for the toxicology.

The affidavit account of the discovery [S247]

From Off. Josephine's statement in the warrant affidavits, the earliest narrative in the corpus.

• Dispatch at approximately 1811 hours: "all cruisers respond to 47 Summer Street for a female that possibly attempted suicide and had lacerations to her wrists and neck and jumped from a second-floor window."
• He found Ms. Clancy on her back "with blood in her mouth."
• Mr. Clancy came out of the far room and stated "she killed the kids".
• In the rear room, the younger boy on his back, unresponsive, "blue and purple in his face," apparent bruising to the neck, and "a blue resistance band next to the child's head."
• The basement layout: to the right, "a weight room style room and an office"; to the left, "a living room area with couches." Patrick's own statement places Cora and Callan in the main living room and Dawson in his office, which matches where each was found.

Patrick's contemporaneous account of the ligatures: all three children had workout bands "tied around their necks." See 08-open-questions.md, where this is now the earliest of his three differing descriptions.

The scene, from McKelligan and Melo

Sgt. Joshua McKelligan, the case officer, reached the house in the early hours of 2023-01-25 and walked the jury through crime-scene video: blood on the bedroom floor near the bed, a bloody knife resting on the nightstand. Sprague drew attention to the absence of significant blood spatter on the walls, consistent with Crook. He was the Commonwealth's last witness that day and also took the jury through the Museum of Science video from weeks earlier. TEST McKelligan [S242]

His account of the medical examiner interview matters more than any of that. He recalled her telling him that "after unconsciousness, it would take several more minutes for someone to die" [S242]. That puts the several-minutes figure into trial evidence rather than leaving it in the 2023 charging materials, and it is the figure the window arithmetic turns on. See 08-open-questions.md.

Sgt. Cory Melo testified to the search: several journals, a postpartum anxiety workbook, a laptop, workout bands, and a cell phone. He also described an Apple Watch turned over after the search warrant had been completed, with pills found in the same drawer. TEST Melo [S241]

Why that last detail is worth keeping. The Apple Watch is the source of the heart-rate evidence, and Reddington's cross of Whiffin turned on not knowing who had possession of the devices after 5:38 pm [S210]. A watch surrendered after the warrant, rather than seized during it, sits inside that gap. Nobody is recorded joining those two facts.

Dr. Cristina Carpio, trauma surgeon, South Shore Hospital

The witness who treated Clancy's own injuries, added 2026-09-05. She was absent from this corpus entirely until the transcript index surfaced her, which is a significant prior gap given that the seriousness of the suicide attempt was among the most contested questions in the case.

Two things follow. Her fall height, disputed in this corpus between Laposata's 13 to 14 feet and a reported 20 feet, is given by the treating trauma surgeon as roughly 20 feet. And a core temperature of 82.1 F is profound hypothermia, which no source in this corpus discusses. It is consistent with a prolonged period lying outside in January, and a thoracic cord injury impairs thermoregulation below the level of the lesion, so hypothermia would develop faster than in an uninjured person. Nobody is recorded arguing what it implies about how long she lay there or about the seriousness of the attempt.

What the first responders saw, from the Day 3 transcript [S233]

Off. Stephen Hall. Dispatched about 6:11 pm. Found Lindsay near the window well, semi-conscious, head toward the house. Cuts to both wrists and the left side of the neck, "not actively bleeding," and on his training he did not think they required immediate medical intervention. He found Dawson in a back room of the basement, on his back, shirtless, "discolored, like a bluish purple," with a yellow exercise band nearby. He noted exercise bands tied to a closet door in the workout room, which is where the ligatures came from. Outside, he saw the open window with blood around the frame and on the shingles, and "saw no torn or ripped screens on the ground."

Off. Brian Josephine. Arrived within three or four minutes. She "mumbled" without definitive responses. Cuts to the right wrist and right side of the neck, "bleeding but not profusely," and on his first-aid training no tourniquet or pressure was needed and the cuts were not life-threatening.

Neither officer described how the bands were configured on the necks. By the time they arrived Patrick had removed them.

The screens. Hall's observation is the only physical evidence in this corpus bearing on the window screen, and it is consistent with Heilbrun's testimony that the screen was not cut [S213].

The two suicide-attempt questions, which this corpus has been conflating. This paragraph is the wiki's own reasoning. The dispute over whether the suicide attempt was "real" collapses two separate findings. On the cuts, the evidence is now consistent across three witnesses: Crook found no spray and a pattern suggesting someone standing still [S33][S236], and both first responders independently assessed the wounds as superficial and not life-threatening [S233]. On the fall, the evidence is equally consistent the other way: a shattered spine, permanent paralysis, intubation, and a cardiac arrest requiring a massive transfusion protocol [S41][S32]. Saathoff's concession, that shallow lacerations do not show she was not intending to die [S107], and Heilbrun's "highly lethal and very serious" [S108] are best read as describing the fall, not the cuts. Stated that way the experts are not in conflict at all, and the Commonwealth's "minor scratches" framing at the 2023 bail hearing [S204] addressed only the half of the attempt that did not nearly kill her.

Her injuries and hospital course

Discovery and response

The 2022-08-23 laptop session, resolved

From the Day 13 transcript [S232]. Sgt. Kyle Pavao, MSP Cyber Crime, examined a Surface Pro seized in 2023 and extracted in September 2025. The sequence, to the second:

This closes the conflict previously logged between the online claim that Patrick's email was signed in and the testimony that the session began from Lindsay's Facebook. Both are true. The Facebook account visited was Lindsay's; the Chrome default profile was signed into Patrick's email, which Pavao did not initially identify as Patrick's. The path from a musician to a suicide-methods page was entirely hyperlink navigation, not searching [S232].

Two further points from the same testimony. Pavao found no searches for "ways to kill" [S232]. And the path to the suicide-methods page was not in his October 2025 report; he identified it only after the DA's office asked him to revisit the analysis on 2026-07-26, days before trial.

Other Surface Pro searches he confirmed: Lamictal, a Zoloft comparison, DBT, definitions of mania, and "Ketamine for benzo withdrawal" on 2023-01-18 [S232]. That last date is the day Sprague's closing identified as the point her medication journal stopped and "it's as if she's decided she's done trying" [S46]. On the same day she was researching a novel treatment. Neither side is recorded putting those two facts together.

The prior night, 2023-01-23

• She accessed photographs of the children on her phone and modified them. TEST Chiappini [S7] No source here states what the modifications were.
• A note on her iPhone was modified one day before the deaths, placing it on this date: "Medication stole my motherhood and my life... prescription medication stole me from my own body." TEST digital forensics, read into the record [S39][S42]
• She attended Cora's birthday party and told her friend Bethany DeCollibus that her sleep was not improving and she felt like "a zombie." DeCollibus observed she looked tired but "didn't look like a zombie." TEST DeCollibus [S10]
• She texted her friend and colleague Andrea Hennigan that she was working with her psychiatrist to find the right medication combination for sleep. "It's been difficult." TEST Hennigan [S10]
• She had her final appointment with Dr. Tufts, by video. See 06-medication-psychiatric.md. TEST Tufts [S19][S35]
• Cora's teacher told her at pickup that Cora had repeatedly needed the bathroom. She said she would raise it with the doctor the next day. TEST Susan Bertolo [S10]

The convergence matters: on the same day she wrote that medication had stolen her from her own body, she was told about her daughter's stomach trouble, made a pediatric appointment for the next morning, and told a psychiatrist she had no suicidal or homicidal ideation. The Commonwealth read the ordinary conduct as evidence of capacity; the defense read the note as evidence of what was happening underneath it.

From the charging documents and arraignments

Facts stated by the Commonwealth at the 2023 arraignments and in the unsealed search warrants, most of which were later put to the jury in some form. PROS unless marked.

How the bands were fastened, contested. The Commonwealth's 2026 motion set Patrick's spontaneous 911 account, which it said "negates any theory that they were tied or knotted," against his later police and grand jury accounts of a knot at the back of Cora's and Callan's necks, "looped like you would tie a shoelace but came off easily," and Dawson's "tighter" and pulled over his head. The Commonwealth argued the distinction is "probative of whether the defendant tied the bands around the neck of each child and walked away, or whether she manually pulled the bands around each child's neck until they died." PROS [S141] Which version the jury was asked to accept is not reported.

The defense answer to the timing theory

Added 2026-09-06 from Patrick Clancy's cross-examination on day 2 [S309, ASR, unverified]. The corpus recorded the Commonwealth's timing theory but not the answer to it.

Established first: the CVS was about a three-minute drive from the house, the restaurant about nine minutes.

Then, to Patrick:

"She was home with the kids for two days. Is that right?" "Right." "If she wanted to kill the kids, she certainly could have done it that time when you're out, right?" "In theory." "As opposed to sending you on a three-minute trip to CVS and a nine-minute trip to a restaurant, you were away for two days in November and on a number of occasions for brunch as well as skiing, right?" "Yeah."

DEF [S309, ASR, unverified]

The same fact, read two ways. The Commonwealth argues the twelve-minute errand shows calculation [S305][S302]. The defense argues a planner would not choose the shortest available window over repeated longer ones. Neither side is recorded resolving it.

This wiki's reasoning. The defense argument depends on an assumption it does not state: that the intent, if any, was constant from November onward. If intent formed later, the November absences establish nothing, because there was nothing yet to act on. The corpus places the sharpest deterioration in December, with the medication switch, the disclosure of thoughts of harming the children, the Women and Infants admission and the McLean admission all falling after the November absences [S6][S11][S39]. On that chronology the two-day trip in November is not a missed opportunity; it is a period before the question arose.

This does not dispose of the defense point, which retains force against a claim of long-settled planning. It narrows it to the window after intent could have formed. Nothing in this corpus records the Commonwealth making this answer, and it is recorded here as reasoning rather than as argument that was put to the jury.

The delay in reaching 911

"At what point did you call 911?" "I don't know the exact time, but it took a few minutes because my phone was switching between Wi-Fi and [cellular]. So I almost just started calling out for the neighbours, but eventually it went through."

PRESS Patrick Clancy, via ASR [S309, ASR, unverified]

The corpus records the call as placed at roughly 6:00 pm and running about six minutes [S3]. It did not record a failed interval before it connected, or that he nearly went to the neighbours instead.

A conflict on the depth of the wrist injuries

Logged rather than smoothed. These are honest accounts from different vantage points: a layperson at a dark scene and a physician in a trauma bay. The clinical account is the reliable one on depth, and the physician separately agreed the open wrist wound went through subcutaneous tissue [S307]. Patrick also testified the wounds were not actively bleeding and that he did not feel the need to apply pressure when the 911 operator raised it. [S309, ASR, unverified]

Callan: the findings behind the cause of death

Added 2026-09-06 from the day 8 transcript [S312, ASR, unverified]. The corpus held Springer's conclusion [S10] but not the basis for it.

PRESS Springer, via ASR [S312, ASR, unverified]

Mechanism as explained: the vessels supplying the neck are compressed, the jugular veins being a lower-pressure system and the carotid arteries higher, and a backup of blood in the head raises pressure in the small vessels until they rupture.

Why the cause of death reads "complications of mechanical asphyxia." Asked directly:

"Because he was resuscitated and so his heart began to beat again. From the 24th to the 27th there was a continuation of support of his organs in the hospital. If he had a stopped heart at the scene, in that case I would have just said mechanical asphyxia, but since there was a three-day hospital stay I said complications of mechanical asphyxia."

The word does not mean anything happened at the hospital, and the witness said so. It reflects the successful resuscitation Dr. Kaufman described on day 4: CPR on arrival, epinephrine, and a heartbeat restored under ultrasound before transfer to Boston Children's [S306]. The two days explain each other and neither did so alone.

This wiki's reasoning. Olson described Cora and Dawson as each having a horizontally oriented linear ligature furrow with pallor and distinct upper and lower borders [S256]; Springer describes Callan as having discrete linear abrasions in three locations. Whether that difference is forensically significant is beyond this corpus, and no witness in the extracted material was asked to compare them. It is recorded so that nobody later treats the two descriptions as identical.

Cora: the ligature findings in detail

Added 2026-09-06 from the day 12 transcript [S313, ASR, unverified]. The corpus held a one-line summary [S256]; the definitions and the detail were not in it.

As the medical examiner defined the terms: a ligature is "an object used to apply external force to the neck or compress the neck," and a furrow is "the pattern of injury that develops underneath the site of compression," which "can be an imprint, it could be a pattern, or it could be more developed types of injuries such as bruising or abrasions."

PRESS via ASR [S313, ASR, unverified]. Photographs 7784, from the left, and 7782, the front of the neck.

The petechiae location is more specific than the corpus recorded. It held "diffuse facial petechiae" [S256]. The testimony places them inside the eyelids and inside the lips, which the witness found by inverting the eyelids and opening the lips.

On the configuration question. The furrow encircled the neck, with distinct edges front and back and bruising at the edges behind. That establishes encirclement. It does not establish knotting, and the witness was not asked about it in the extracted material.

What a firefighter saw, and the configuration question

Added 2026-09-06 from the day 3 transcript [S317, ASR, unverified].

A first responder heard a scream that "sounded like it was coming from the basement," looked through a lit basement window, and:

"After I heard the scream, I saw a male, an older male gentleman, now knowing it was Patrick Clancy, unwrapping something from a child's head."

PRESS via ASR [S317, ASR, unverified]

This is the observation the Commonwealth built on in closing. Its argument was that the bands "weren't knotted. They weren't tied. They don't just stay there on their own," and that firefighters "see him in an unwinding motion, unwrapping" [S302]. Set against it: Patrick testified he untied each band as he found them [S3][S40].

The corpus now holds both accounts of the same moments and they are not the same act. Unwrapping, seen through a window by a witness who had just arrived, is not untying, described by the man doing it. Neither witness was asked to reconcile them, and this corpus does not choose between them.

The window screen. Asked whether he saw any ripped or torn screens on the ground in the backyard, the same witness answered "No" [S317, ASR, unverified]. That is consistent with Heilbrun's account that the screen was not cut [S213] and with her telling a Commonwealth expert she had slashed it when she had not [S315]. It is not an observation of the screen in the window frame, which no witness in the extracted material was asked about.

Other findings from the same day: blood marks on the upper window and at the top of the lower window, exhibits 105 to 108; Clancy found directly below that window, to the right of a metal window well; and a paramedic's lay description of Cora as having "burst blood vessels around her eyes," the finding the medical examiner later described as petechiae [S313].
