The Commonwealth rested after Ian Whiffin's digital-evidence testimony, and the court denied the defense's Rule 25 motion. Defense witnesses described Clancy's nursing work, reported mental-health difficulties, and injuries, while cross-examination addressed limits on their observations and accounts of improvement.
Full day summary
Ian Whiffin completed his testimony about phone and watch records, explaining their timing and limitations. He clarified that the 5:33:34 PM flight-climb timestamp marked recognition of a completed climb, not its start. The last recorded heart rate was at 5:23:52 PM, and he did not believe either device recorded further climbs between 5:38 PM and 6:09 PM. He could not explain the absence of later activity or establish subsequent physical movement from the records alone. He also could not identify who performed the searches or reconstruct the Apple Note's exact changes. On redirect, he said the January 25 printout alone could not distinguish phone activity from watch activity and that an operating phone records movement regardless of who carries it.
After the Commonwealth rested, the defense sought a required finding of not guilty or reduction to second-degree murder, arguing that the Commonwealth had not rebutted evidence of lack of criminal responsibility. The Commonwealth argued that the criminal-responsibility motion belonged at the close of all evidence. The court denied the motion under the standard applicable at that point and noted the defense objection.
The defense then called coworkers and family members. Nurse Margaret Hamp described Clancy as compassionate with patients but acknowledged that she had not seen her after Callan's birth. Clancy's sister, Allison Ozga, described worsening depression, insomnia, and suicidal thoughts in late 2022. She believed Clancy had reported daily suicidal ideation for a month. On cross-examination, Ozga acknowledged earlier statements that Clancy seemed okay in January and clarified that most communications were texts; she could not recall phone calls.
Clancy's mother, Paula Musgrove, described anxiety, insomnia, fear of being alone, and a December disclosure of thoughts of harming the children. She said she had not considered commitment and was not concerned for their safety because she was there. Prosecutors questioned her about positive texts and periods away from the home. Musgrove said her January 22 message about improvement was encouragement, not necessarily a description of her observations, and qualified her recollection of police statements.
After instructions on evaluating expert testimony, emergency physician Michael Vulfovich described severe hypothermia, lacerations, spinal fractures, internal bleeding, and cardiac arrest from his review of photographs and hospital records. The court sustained objections to questions about suicide attempts and feigned suicide. Vulfovich described self-injurious behavior but said he could not gauge intent. The Commonwealth declined cross-examination.
