On day five of Richard Allen’s murder trial, jurors heard testimony from the forensic pathologist who performed the autopsies of Abby Williams and Libby German, as well as from a witness who saw the ‘Bridge Guy’ on the day of the murders.

Dr. Ronald Kohr, who previously reported that he believed two knives were used in the killings, testified that he now believes the ‘serration’ seen in some of Libby’s wounds was likely caused by an element on the handle of the blade.

Using photos of the injuries displayed on a large projection screen, Kohr suggested that a box cutter with an extra thumb grip could have been the sole murder weapon.

This testimony surprised Allen’s defense team and directly contradicted Andrew Baldwin’s opening statement, aligning instead with the state’s claim that Allen used a box cutter to slash the girls’ necks. Family members wept as the photos were shown in court, and many jurors briefly averted their eyes to maintain composure.

Allen and his defense team closely followed Dr. Kohr’s testimony.

Sarah Carbaugh, a lifelong Delphi resident who was walking her dogs on the afternoon of February 13, 2017, also testified about her sighting of the ‘Bridge Guy.’ She said she saw a man walking west on Country Road 300, covered in blood and mud, as if he had fallen on the trail.

Carbaugh later recognized him from the video clip released from Libby’s phone, but waited three weeks to report the sighting due to anxiety.

Allen’s defense questioned Carbaugh about discrepancies in her description during cross-examination, noting that her recorded interview mentioned blood only once. Baldwin also pointed out unusual details in her description, including her remark about the man’s “effeminate eyes.” Carbaugh pushed back, reminding Baldwin that over an hour of her interview video had been accidentally destroyed.
