New digital data was provided Tuesday by Stacy Eldridge, a digital forensic examiner. She claims she used data pulled by Indiana State Police years ago from Libby German's cellphone to determine someone inserted a headphone jack into the phone on the evening the girls went missing. It was then pulled out about five hours later. That's the first time ever we've heard the possibility of someone else tampering with Libby's phone that night. We also heard about two hours of testimony from a forensic scientist about the "cycled, unfired round" found at the crime scene between the girls' bodies. Dr. Eric Warren on Tuesday was critical of how state police handled the examination of the cartridge, essentially saying the findings were inconclusive. Also on Tuesday, a psychiatrist who specializes in solitary confinement shared what he calls "common symptoms" of people who are confined for too long, including confusion and delirium. After watching videos and listening to phone calls of Richard Allen in solitary confinement, the doctor concluded he was "absolutely" showing signs of delirium, supporting the defense's argument that Allen's mental health had deteriorated when he confessed to killing Abby Williams and Libby German in February 2017.
