About
Timothy Chiappini testified for the Commonwealth on Day 13 about his extraction and analysis of Lindsay Clancy's iPhone. The State Police investigator explained hash verification and described an advanced logical extraction as the most comprehensive he could perform at the time, not access to every possible item of phone data. The court admitted reports on a disk as Exhibit 236.
On direct examination, Chiappini read notes describing depression, parenting concerns, breastfeeding, sleep and medication, then reviewed photographs, searches, messages and calls. These were digital records, not his clinical findings. He explained that multiple report entries could reflect one search and that a note's last-modified date did not reveal each edit or what changed. His explanations for simultaneous browser entries and zero-duration calls remained inferences.
On cross-examination, Kevin Reddington developed records concerning psychiatric care, psychosis, suicide, medications, sleep and childcare, alongside family communications. Chiappini acknowledged matching device identifiers on three documents containing suicide-related and airbag searches but declined to confirm their attribution to Lindsay's phone. Those documents were marked R, S and T for identification only. He also qualified what photograph modification metadata could establish and said he had not participated in the house search. His testimony identified records relevant to the mental-health issues without offering a diagnosis or opinion on criminal responsibility.
On redirect, Chiappini confirmed that the defense's psychosis- and drug-search materials were available in Exhibit 236. He distinguished a recorded search for psychosis symptoms from an inferred purpose and confirmed a message from Lindsay's mother saying she had seen Lindsay doing better. On recross, he identified message sets involving Patrick Clancy and Sue Clancy. Reddington offered them, Sprague objected, and the judge called a sidebar. No admission ruling is recorded before Chiappini was excused.
