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.

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

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

A state’s witness testified that she saw a man, who later came to be known as “Bridge Guy,” covered in blood and mud on the day of the Delphi murders, but became combative during a tense cross-examination as the defense pointed out discrepancies between her testimony and her previous statements to police.

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.

Witnesses testifying at the trial of the man accused of killing two teenage girls in Delphi, Ind., were questioned about the so-called "Bridge Guy," seen walking on the hiking trail where the girls were murdered.

A witness in the Delphi murders trial described seeing a bloody, muddy man on the trail the day the victims disappeared.

The State of Indiana called the witnesses for day four in the Delphi murders trial, but the prosecution’s plan may not have worked out how it was intended.

Due to a labeling mix-up, a tip that defendant Richard Allen was seen on the Monon High Bridge on the day of the murders of Abigail Williams, 13, and Liberty "Libby" German, 14, in 2017, was not reviewed after September 2022.
