Prosecutors in the murder trial of Lindsay Clancy are relying on digital forensics to reconstruct the hours leading up to a 2023 triple homicide in Massachusetts. The evidence centers on health data and communication logs pulled from her iPhone and Apple Watch.

Digital forensics expert Ian Whiffin of Cellebrite provided testimony regarding the device logs. The prosecution presented search history logs from the period immediately preceding the deaths. These records include queries about psychiatric medications and specific pharmacy locations. Additional logs show phone activity, including incoming and outgoing calls to her husband, Patrick Clancy.

Beyond call logs, the prosecution introduced health data recorded in the Apple Health app. The records indicate the defendant climbed two flights of stairs at specific times on the day of the incident. Testimony also highlighted heart rate measurements captured by the watch, which prosecutors presented as part of the timeline of the defendant's actions.

The defense team questioned the reliability of the electronic data during cross-examination. Attorney Kevin Reddington focused on discrepancies in the recording times of the devices. The records show the devices stopped logging data at different points in the evening, leading the defense to challenge the accuracy of the prosecution's digital timeline.

This trial highlights the role of consumer health technology in criminal investigations. Text messages, notes stored on mobile devices, and biometric data continue to provide technical context in legal proceedings. The court is examining how this digital trail maps to the defendant's behavior and the prosecution's theory of premeditation.
