The trial of Richard Allen for the Delphi murders resumed Wednesday with testimony from an eyewitness, a forensic pathologist and a police technician.

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.

Tuesday was the first time prosecutors revealed a portion of the video that shows a man who they allege is Richard Allen.

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

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.

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.
