Ernesto Cervantes was 19 when he was shot and killed in East Los Angeles on July 31, 2016. Around 3:28 a.m. on the 200 block of North Alma Avenue, he was walking south when he passed a house where a party was underway and exchanged brief words with people in the front yard. Shortly afterward at least two people in the yard opened fire; Cervantes was struck multiple times, attempted to run, collapsed in the street and was pronounced dead at about 4 a.m.

Investigators say some vehicles on the street were struck by stray bullets and there was speculation Cervantes might have returned fire, but no weapon was found on him and the house did not appear to have been hit. Witnesses described the shooters only as Latino. The Los Angeles County Sheriff’s Department reports that reluctance among partygoers and other witnesses has hampered the inquiry, and the Homicide Bureau is asking anyone with information to contact them or submit anonymous tips to Crime Stoppers.

Was anyone in the neighborhood that night who remembers what happened or saw people leaving the party?
