@investigationdiscovery: When a UC Davis officer found Andrew Mockus beside the railroad tracks, his bicycle was still lying next to him and there was no one left to explain what happened. Investigators could not yet say whether the 14-year-old had been murdered, had an accident, or taken a dare. In a town where everyone knew everyone, names and rumors moved through Davis long before the facts did. Watch "A Killer Among Friends" Mondays on ID and stream on @HBO Max. #AKillerAmongFriends @therealjlhewitt
