Larry Medina was 20 years old when he was fatally stabbed at a residence in the Los Serranos neighborhood of Chino Hills, California, on February 6, 2006. The San Bernardino County Sheriff’s Homicide Detail investigated the killing, but the case remains unsolved and is listed as a cold case.

Los Serranos has a history of gang-related activity and incidents in the area have been linked to local gangs and larger organized crime affiliations such as the Mexican Mafia and regional street gangs.

Anyone with information is asked to contact the San Bernardino County Sheriff’s Department, which has established anonymous tip lines to assist in bringing justice for Medina and closure for his family. Did anyone in the Los Serranos area at the time see or hear anything that could help this investigation?
