Lindsay Clancy’s final movements before the deaths of her three children were apparently captured by the devices inside her home.
The Massachusetts mother is accused of strangling Cora, five, Dawson, three, and eight-month-old Callan in the basement of their Duxbury home in January 2023.
Although Clancy does not deny killing her children, she has pleaded not guilty, claiming she is not criminally responsible because she was suffering from postpartum psychosis after being prescribed a powerful cocktail of drugs.
On Monday, the 14th day of her trial, prosecutors revealed how data from Clancy's Apple Watch and iPhone recorded her heart rate, phone activity and apparent movement around the house before the health and movement records stopped at 5.38pm.
The evidence was presented by Ian Whiffin, a digital-forensics expert with Cellebrite who analyzed a full extraction of data from Clancy's iPhone 13 for the prosecution.
