@abc7chicago: Testimony went late into the evening on Tuesday in the double murder trial of Richard Allen. Prison staff testified about Allen's multiple confessions and behavior while behind bars. Libby, 14, and her best friend Abby Williams 13, were walking along a hiking trail in rural Delphi when their throats were cut and they were left in the woods on Feb. 13, 2017. Their bodies were found the next day. Allen was arrested in 2022 and has pleaded not guilty to murder. John Galipeau, a former warden of the Westville Correctional Facility, took the stand on Tuesday.
