The bodies of Liberty German and Abigail Williams were found on Feb. 14, 2017, after the two teens from Delphi, Ind. failed to return from an afternoon on the Monon high bridge.
The haunting images and video from their final moments caught on the cell phone of 14-year-old Libby, and the twists and turns of the highly-scrutinized investigation drew national attention.
Police released two completely different suspect sketches years apart, held several intense and slightly mysterious press conferences and released few details in the case over the course of a five-year investigation.
On Oct. 31, 2022, police announced they arrested and charged 50-year-old Delphi resident Richard Allen with two counts of murder in the deaths of Libby and Abby.
