Juan Marquez, 39, was shot and killed in Bloomington, California, in the early morning hours of March 5, 2017. Deputies from the Fontana Sheriff’s Station responded about 1:07 a.m. to reports of gunfire in the 18100 block of Santa Ana Avenue and found Marquez in a driveway with a gunshot wound; he was pronounced dead at the scene despite emergency medical efforts.

The San Bernardino County Sheriff’s Department opened a homicide investigation and assigned detectives from the Specialized Investigations Division, Homicide Detail. Investigators processed the scene, interviewed potential witnesses and sought tips, but the case produced no immediate leads and remained unsolved. Detectives have periodically revisited the investigation and have been asking the community for information, offering anonymity through the We-Tip Hotline.

Friends and family remember Marquez as a beloved person who had a positive impact on those around him. Does anyone who lived in or near the 18100 block of Santa Ana Avenue on March 5, 2017, or who may have information, have anything to share with investigators?
