Ret FBI Jennifer Coffindaffer Breaks Down The Health Data On John O'Keefe's Phone

True Crime Today | A True Crime Podcast

In the recent episode of "Hidden Killers With Tony Brueski," retired FBI Special Agent and Hidden Killers Daily Contributor Jennifer Coffindaffer discussed the intricacies of John O'Keefe's health data from his Apple Watch and phone. The focus was on the discrepancies between the Commonwealth's assertions and the actual data recorded. The Apple Watch data showed that O'Keefe took 80 steps and ascended or descended three flights of stairs, contradicting the Commonwealth's narrative that he was outside at the car. The timeline was further complicated by data indicating that someone holding O'Keefe's phone took 36 steps and traveled 25 meters at 12:32 a.m., after Karen Reed had left the location at 12:30 a.m.
Coffindaffer emphasized that every witness testified that O'Keefe did not enter the house, and she doubted a conspiracy to lie was plausible. She argued that GPS data from O'Keefe's phone was a more precise indicator than the health data from his Apple Watch, suggesting the Commonwealth's case was weakened by their reliance on less accurate data. Coffindaffer also critiqued the expertise of the Commonwealth’s witnesses compared to the defense’s expert, Rick Green, whose testimony was effectively challenged by the prosecution. Tony Brueski and Coffindaffer agreed that the health data application was less reliable than cellular phone data, and they believed it was a mistake for the prosecution to continue pushing the narrative that O'Keefe entered the house, as the data did not support it.
