Alvaro Castro, 41, of Paramount, California, was shot dead while riding his bicycle along the Los Angeles River Bike Route near the 6500 block of San Juan Street on May 9, 2018. The shooting occurred about 5:15 p.m.; he was pronounced dead at the scene at 5:39 p.m. The Los Angeles County Sheriff’s Department found him lying by the bike path.

Investigators say no witnesses have come forward with a clear account. Some people were seen fleeing the area, but it is unclear whether they were running out of fear or were involved. No suspects have been identified or arrested. Castro’s death was one of two homicides in Paramount within a 24-hour period, but investigators report no evidence linking the cases; the other victim, Jorge Alberto Esteban, was shot in a gang-related incident about a mile away.

Castro’s family, who live nearby, have been left devastated. Anyone with information is asked to contact the Sheriff’s Homicide Bureau or Crime Stoppers. Did anyone in the area see or hear anything that evening?
