Christopher Ian Vandebrooke, 48

Christopher Ian Vandebrooke, a 48-year-old white man, died of stab wounds Friday, Dec. 16, in the 3000 block of Riverside Drive near Griffith Park, according to Los Angeles County coroner’s records.

About 7 a.m., police were called to a small homeless encampment after a person witnessed a stabbing, Los Angeles Police Det. Lewis Lenchuk said.

The witness awoke to the victim screaming, Lenchuk said.

Vandebrooke was taken to a hospital where he was pronounced dead at 8:22 a.m., according to coroner’s records.

Michael Ernest Chacon, a 65-year-old Latino, was arrested on suspicion of murder Dec. 19, according to L.A. County Sheriff’s Department online records.

What led to the stabbing is unknown, Lenchuk said.

Chacon was charged Dec. 21 with one count of murder with an allegation that he used a knife, Ricardo Santiago, a spokesman with the Los Angeles County district attorney’s office, said in an email.

Before Chacon could be arraigned, a “doubt was declared” about his ability to defend himself, so he was sent to the mental health court.

Chacon is due back in court March 2 for an update on the mental health proceedings, Santiago said.

Anyone with information can call Lenchuk at (323) 561-3421. Those who wish to remain anonymous can call Crime Stoppers at (800) 222-8477.
