Crime Scene and Investigation

Crime Scene Response

The investigation began during the emergency response to the Clancy family residence on Summer Street in Duxbury on January 24, 2023. At approximately 6:11 PM, Duxbury Police, firefighters, and emergency medical personnel were dispatched after Patrick Clancy reported that Lindsay Clancy had jumped from a second-story window. Responding officers found Lindsay conscious but seriously injured on the ground outside the home beneath an upstairs bedroom window.

While officers and medical personnel attended to Lindsay, Patrick entered the residence to check on the couple’s children. Officers then received an urgent report that the children had been found in the basement and were not breathing. Police entered through the rear sliding door, moved through the house, and descended to the finished basement, where Cora, Dawson, and Callan were found unresponsive in separate areas.

Officers observed exercise or resistance bands around or near the children’s necks. The bands were removed and lifesaving measures were initiated. Police, firefighters, and emergency medical personnel performed CPR and transferred the children for emergency treatment. Cora and Dawson were transported to Beth Israel Deaconess Hospital in Plymouth. Callan was initially treated there and then flown to Boston Children’s Hospital. Lindsay was transported for treatment of lacerations, spinal trauma, and injuries from the fall.

After the victims were removed, officers secured the residence and treated it as an active homicide scene. Access was restricted, a perimeter was maintained, and investigators documented those entering and leaving the property. Duxbury Police were joined by Massachusetts State Police detectives assigned to the Plymouth County District Attorney’s Office, Massachusetts State Police Crime Scene Services personnel, and a forensic chemist.

Crime Scene Processing

Investigators conducted an initial walkthrough before beginning the detailed search. The exterior, the area beneath the second-floor window, the interior rooms, the basement, and the locations where the children were found were photographed and documented. Investigators preserved the condition and placement of furniture, exercise equipment, household items, electronic devices, stains, and other potential evidence before moving or collecting items.

The finished basement was a central focus of the examination. Police reports described the children in separate locations within the lower level. Investigators documented resistance bands and other exercise equipment near the children and recorded the location of each item before collection. The basement rooms, pathways, furnishings, workout area, and surrounding surfaces were photographed and examined for biological, trace, impression, and fingerprint evidence.

The second-floor bedroom and window area were also processed as significant parts of the scene. Officers had observed blood on or near the window frame. Search-warrant returns later documented swabs from red-brown stains on the bedroom floor, mirror, windowsill, nightstand, and other areas. Investigators also examined the exterior ground beneath the window and collected swabs from the backyard and additional locations where apparent biological material was present.

The residence was searched for evidence of forced entry, an outside offender, a struggle, weapons, ligatures, medications, writings, digital devices, surveillance systems, clothing, footwear, fingerprints, shoe impressions, and biological material. The warrant affidavits described the scene as part of an investigation into murder, assault and battery with a dangerous weapon, and strangulation.

Hospital and Medical Investigation

Investigators were assigned to the hospitals receiving the children and Lindsay. Trooper Joseph Rabbitt responded to Beth Israel Deaconess Hospital in Plymouth, where Cora was in Exam Room 3, Dawson was in Trauma Room 1, and Callan had initially been treated in Trauma Room 2 before being flown to Boston Children’s Hospital.

Dawson was pronounced dead at 7:28 PM. The treating emergency physician told investigators that Dawson arrived in cardiac arrest and that personnel had been advised an exercise band had been tied around his neck before transport. The physician documented findings consistent with strangulation, including petechiae on the side of his face, along with bruising on his right knee and an older bruise on his shin.

Cora was also pronounced dead at 7:28 PM. Her attending physician reported that she arrived in cardiac arrest and had bruising or burst blood vessels around her head, eyes, and neck. Bruising on her chest was attributed to resuscitation efforts. Investigators photographed Cora, bagged her hands to preserve possible evidence, and arranged for her transfer to the hospital morgue for pickup by the Office of the Chief Medical Examiner.

Dawson was photographed, and his hands were also bagged before transfer to the morgue. Investigators interviewed the physicians who treated Cora, Dawson, and Callan and documented the children’s conditions, injuries, resuscitation efforts, transfers, and pronouncement times. Callan remained in critical condition at Boston Children’s Hospital until his death on January 27, when the investigation became a triple-homicide case.

Trooper Daniel Lawlor responded to South Shore Hospital, where a Duxbury detective advised that Lindsay was considered to be in custody. Police secured her clothing, wedding ring, and wedding band. A later warrant identified her as a patient at Brigham and Women’s Hospital and authorized investigators to photograph her, document her injuries, obtain major-case fingerprints, and collect external swabs.

At approximately 6:21 PM on January 25, investigators conducted the authorized forensic examination. The warrant return documented digital photographs, swabs from beneath or around the fingernails of both hands, and a nursing progress note describing her injuries.

---

Witness Interviews

Investigators interviewed the first responding officers during the evening of January 24. Officer Brian Josephine described the dispatch, Lindsay’s location outside the residence, Patrick’s return into the house, the screaming from inside, and the discovery of the children. Officer Stephen Hall described Lindsay as semiconscious, hearing Patrick’s basement report over police radio, entering the house, finding the children, and observing blood on the second-floor window frame. Officer Vincent Cahill described the infant’s neck injuries, the resistance band, Patrick’s statements about leaving to obtain food and medication, and Patrick’s observation that the home was unusually quiet when he returned.

At approximately 8:40 PM, Lieutenant John Santos and Trooper Rabbitt conducted an audio-recorded interview with Patrick at Beth Israel Deaconess Hospital. Patrick described Lindsay’s anxiety beginning in September 2022, her psychiatric providers, medication history, late-December suicidal thoughts and thoughts of hurting the children, her January hospitalization, the errands to CVS and ThreeV, his return to a quiet house, the blood and open window, finding Lindsay outside, and finding the children in the basement with workout bands around their necks.

Patrick told investigators that he and Lindsay had an “amazing marriage” and got along well. He consented to photographs of his face, hands, clothing, and general appearance. Investigators compared his account with surveillance footage, receipts, dispatch records, travel-time calculations, medical findings, and the physical evidence recovered from the residence.

Hospital physicians were interviewed separately regarding each child. Investigators also interviewed or worked with the ThreeV restaurant manager and the Kingston CVS manager to verify surveillance-system times, identify Patrick’s movements, preserve recordings, and establish the chain of custody for the video evidence.

---

Surveillance and Timeline Reconstruction

Investigators obtained surveillance footage from CVS Pharmacy at 189 Summer Street in Kingston and ThreeV restaurant at 10 Cordage Park Circle in Plymouth. The footage was used to verify Patrick’s account and define the period during which Lindsay was alone with the children.

• CVS video showed Patrick in the store from 5:32:32 PM until 5:37:08 PM.
• He went to aisle 20, identified by the manager as the children’s medication aisle, remained there for several minutes, appeared to use his cellphone, went to the register at 5:36:12 PM, and exited at 5:37:08 PM.
• Patrick told police that he purchased Pedia-Lax for Cora. The CVS bag and medication were later seized from the residence.
• ThreeV video showed Patrick entering at 5:54:14 PM, looking toward the takeout area, waiting behind another couple, and using his cellphone while he waited.
• At 5:55:01 PM, he paid for the order with an American Express card. Restaurant personnel confirmed the accuracy of the surveillance-system clock.

At approximately 9:09 PM, investigators went to ThreeV, reviewed the system, confirmed the timestamps, and arranged for an outside vendor to export the footage. At approximately 9:40 PM, investigators went to CVS, confirmed the timestamp with the manager, and downloaded the video to a USB flash drive for evidence storage.

Investigators calculated the travel time as approximately three minutes from the residence to CVS, eight minutes from CVS to ThreeV, and nine minutes from ThreeV back to the residence. They compared those calculations with the store videos, receipts, Patrick’s statements, cellphone and transaction records, and the approximately 6:11 PM police response. The warrant affidavit placed the alleged attacks within the period Patrick was away from the home.

---

Search Warrants

At approximately 3:00 AM on January 25, Trooper Joshua McKelligan signed and swore to an affidavit requesting authority to search the Clancy residence. The warrant sought evidence connected to murder, assault and battery with a dangerous weapon, and strangulation.

The requested categories included:

• Blood, DNA, and other biological or trace evidence.
• Clothing, footwear, fingerprints, and shoe impressions.
• Handwritten records, journals, notebooks, medical paperwork, and electronic records.
• Cellphones, tablets, laptops, computers, external hard drives, and digital-storage devices.
• Security cameras, smart-home devices, recording equipment, and baby-monitoring systems.
• Prescription medications, pharmacy materials, medication bottles, and treatment paperwork.
• Cutting instruments, sharp objects, exercise bands, resistance bands, belts, and other possible ligatures.

Police executed the residence warrant at approximately 4:50 AM. State police detectives, crime-scene personnel, crime-laboratory personnel, and Duxbury Police participated in the inventory and collection process.

A separate warrant authorized the forensic examination of Lindsay while hospitalized. On January 27, investigators obtained a warrant for an Apple device associated with her. The device warrant sought communications, calls, messages, emails, application data, internet searches, browsing information, location data, photographs, videos, health and fitness information, activity data, and evidence of planning, preparation, motive, intent, or consciousness of guilt.

The Apple-device affidavit was signed at approximately 9:30 AM, and investigators requested authority to perform a full forensic examination of the device and its stored data. A warrant return at approximately 2:00 PM documented an Apple device associated with Lindsay, including visible serial and identifying information. Additional search-warrant materials were signed on February 2 for further examination of digital devices and information recovered during the investigation.

The Commonwealth repeatedly sought to impound the applications, affidavits, warrants, and returns. Prosecutors argued that public disclosure could compromise the active investigation and reveal identifying or sensitive information. The court allowed the materials to remain impounded while investigative work continued.

---

Digital Evidence Investigation

Electronic evidence was collected to reconstruct activity before, during, and after the deaths. Investigators seized two pink iPhones, several tablets, computers and laptops, a Toshiba hard drive, a digital video disc, Google and Ring equipment, Google Nest cameras, and a baby monitor. The warrants authorized forensic preservation and examination of the devices rather than relying only on what was visible through ordinary use.

Investigators sought to recover and compare:

• Incoming, outgoing, and missed calls.
• Text messages, iMessages, emails, application communications, and deleted communications.
• Internet searches, browsing history, downloads, cached information, and application use.
• Photographs, videos, notes, calendars, contacts, and stored documents.
• GPS, location services, Wi-Fi connections, device movement, and account-location information.
• Health, fitness, step, activity, and device-use information.
• Cloud backups, account identifiers, synchronization records, device identifiers, and potentially deleted data.

The warrants identified state of mind, planning, preparation, motive, intent, timeline reconstruction, and consciousness of guilt as potential evidentiary issues. Investigators compared digital timestamps with the surveillance video, store transactions, dispatch records, travel times, medical evidence, physical evidence, journal entries, psychiatric records, and witness statements.

Smart-home and surveillance equipment was examined to determine whether it contained recorded video, motion events, alerts, timestamps, network records, or other activity associated with the residence. The baby monitor and other connected equipment were also preserved for possible forensic review.

---

Evidence Collected from the Residence

The January 25 warrant return documented a broad collection of physical, documentary, medical, biological, and electronic evidence, including:

• Google, Ring, and Google Nest cameras or related equipment.
• A ThreeV restaurant receipt and a CVS bag containing Pedia-Lax.
• A Toshiba hard drive, a digital video disc, a baby monitor, tablets, computers, laptops, and two pink iPhones.
• A brown journal, a notebook, three books, and McLean Hospital paperwork.
• Multiple medication bottles and related prescription or treatment paperwork.
• Two workout bands and additional brown, yellow, black, and blue belts or exercise bands.
• A knife with a black handle.
• Red pajamas and a pink robe.
• Swabs from red-brown stains on the bedroom floor, mirror, windowsill, nightstand, backyard, and other locations.

Investigators photographed and documented the evidence, assigned identifying information, packaged items separately, and maintained custody for crime-laboratory or digital-forensic examination. Evidence from the children and Lindsay was preserved at the hospitals in coordination with medical personnel and the Office of the Chief Medical Examiner.

---

Forensic and Records Review

The investigation extended beyond the initial scene processing. Detectives continued reviewing biological evidence, photographs, laboratory submissions, hospital documentation, autopsy findings, prescription records, psychiatric records, journal entries, cellular data, digital-device contents, surveillance recordings, transaction records, and witness accounts.

Lindsay’s psychiatric history and medication use became a substantial part of the case. Patrick told investigators that her anxiety began in September 2022 and identified psychiatric providers and medications prescribed during the following months. He also reported late-December suicidal thoughts and thoughts of harming the children, a January hospitalization, and continued treatment after discharge. Investigators collected McLean Hospital paperwork, medication bottles, related records, journals, and notebooks from the home.

The prosecution and defense later interpreted this evidence differently. Prosecutors have argued that the surveillance timing, digital searches, errands, physical evidence, and conduct surrounding the deaths demonstrate planning and awareness. The defense maintains that Lindsay was experiencing a catastrophic postpartum mental-health crisis and was not criminally responsible. Investigators preserved the underlying records and evidence for evaluation by medical, psychiatric, forensic, and digital experts.

---

Continuing Investigation

Following the initial warrants, investigators continued obtaining judicial authorization as new evidence was identified. By February 2, additional affidavits sought further examination of digital devices and information already recovered. From March through September 2023, investigators continued reviewing digital evidence, medical and psychiatric records, journal entries, cellphone data, medication history, physical evidence, and the laboratory and medical findings connected to the children’s deaths.

The investigative record ultimately combined the crime scene, hospital observations, autopsy and medical evidence, surveillance footage, store transactions, travel-time calculations, recorded interviews, digital-device examinations, psychiatric and prescription records, handwritten materials, physical evidence, and biological samples. Those materials became the foundation for the Commonwealth’s reconstruction of January 24 and for the competing prosecution and defense positions regarding planning, mental illness, intent, and criminal responsibility.

Review of the recovered pink Apple iPhone

• Investigators document that cellular telephones routinely contain information useful in reconstructing a suspect’s activities before, during and after a crime.

• They identify the device as a potential source for establishing Lindsey Clancy’s movements, communications, planning, and state of mind surrounding the murders and attempted suicide.

Investigators identify the following categories of information sought from the iPhone:

• Subscriber telephone number.

• Electronic serial number (ESN), International Mobile Equipment Identity (IMEI), Mobile Equipment Identifier (MEID), and other identifying numbers.

• Device configuration information and settings.

• Incoming, outgoing and missed call history.

• Contact lists and address books.

• Calendar entries.

• Memo pad and notes.

• SMS text messages, including incoming, outgoing, deleted and draft messages.

• MMS multimedia messages.

• Saved, opened and deleted voicemail messages.

• Email messages, including saved, draft, sent, deleted and unopened messages.

• Instant messaging conversations and chat logs.

• Internet browser history, bookmarks and favorites.

• Saved and deleted photographs.

• Saved and deleted videos.

• Data stored within third-party applications, including social media applications.

Investigative findings supporting the digital search

• Investigators conclude there is probable cause to believe Cora Clancy, Dawson Clancy and Callan Clancy were victims of murder, strangulation, and assault and battery with a dangerous weapon on January 24, 2023.

• Investigators conclude that evidence relating to those offenses, together with evidence concerning Lindsey Clancy’s attempted suicide, may be stored within the digital contents of her recovered pink Apple iPhone.

Investigators summarize the evidence supporting the forensic examination

• A CVS employee reported that a female telephoned the pharmacy before Patrick Clancy arrived to ask whether children’s laxative was available.

• Patrick Clancy reported during his interview that Lindsey called ThreeV Restaurant to place a takeout order before he left the residence to pick it up.

• Investigators conclude that Lindsey contacted both CVS and ThreeV to facilitate Patrick leaving the residence for an extended period, providing an opportunity to commit the murders and subsequently attempt suicide.

• Investigators note that Lindsey’s pink Apple iPhone was recovered powered on from the bed in the master bedroom adjacent to the open window from which she reportedly jumped.

• Investigators document that notebooks recovered during the residential search contained medication logs, suicidal expressions and references to individuals in whom Lindsey confided, including a person identified as “Sue.”

• Investigators believe the iPhone may identify Sue and other individuals through contact lists, text messages, emails and application data.

• Investigators believe the device may contain internet searches regarding methods of homicide or suicide.

• Investigators believe the phone may contain text messages, notes or social media posts explaining the crimes before or after they occurred.

• Investigators believe the phone may contain an electronic suicide note intended for family members, friends or law enforcement.

• Investigators believe family location-sharing applications may document when household members departed from or returned to the residence, assisting investigators in reconstructing the timeline of events.

Search warrant request

• Based upon the investigation, investigators request judicial authorization to conduct a complete forensic examination of Lindsey Clancy’s recovered pink Apple iPhone.

• The requested examination includes recovery of existing, deleted and recoverable digital information contained within the device.

• The requested search specifically authorizes examination of communications, photographs, videos, application data, internet activity, location information and other electronically stored evidence relevant to the homicide investigation.
