Christian Medrano was last seen alive about 2 p.m. Dec. 5 at his home in the 4700 block of Hammel Avenue, according to the Los Angeles County Sheriff's Department, which circulated a missing person flyer during a search.
"It is our unfortunate duty to announce with great sadness that Christian Medrano has been located deceased," the agency confirmed on Monday.
Christian was pronounced dead at the scene beneath a Cesar Chavez Avenue overpass about 6:15 p.m. on the day he disappeared, according to coroner's officials. He had been shot multiple times.
No one was in custody in connection with the killing, and a description of the shooter was not available.
"What they did to him wasn't right," said Christian's brother, Juan. "God didn't take him away. They took him away from us. No family should go through what we've been going through. It's just really hard seeing my mom cry, my dad, my little brothers, my sister."
A GoFundMe page has been established to help the Medrano family with funeral expenses.
Anyone with information about the case is asked to contact LAPD's Hollenbeck Division.
