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.

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