Richard Allen is accused of killing 13-year-old Abigail Williams and 14-year-old Liberty German on an Indiana trail in 2017. Here are the key moments from the trial.

The man dubbed "Bridge Guy" has long been considered the suspect in the murders of the two teens. Prosecutors have claimed that Richard Allen, charged with murder, was the man seen on the trail.

Jurors saw the infamous "Bridge Guy" video and heard from eyewitnesses who claimed they saw the man on the Monon High Bridge trail.

Three witnesses who were on the Monon High Bridge trail the day Libby and Abby were killed, including one who said she was best friends with Libby's older sister, testified Tuesday that a man they saw on the trail is "Bridge Guy" — the primary suspect depicted in a grainy photo police later shared to aid their investigation.

Tuesday’s proceedings included an account of items found at the murder scene and testimony on the infamous “Bridge Guy” video.

The forensic pathologist who performed the autopsy for Delphi eighth-graders Abby Williams and Libby German the day after they were found dead in the woods near the Monon High Bridge Trail in February 2017 backtracked on the stand.

Day 5 of the Delphi Murders trial included testimony from a witness who claims to have seen "Bridge Guy," the day Abby Williams and Libby German went missing.
