A parolee pleaded not guilty today in the killing of a young man last month in Long Beach.

Quentin Eugene Anderson, 54, was charged Feb. 15 with one count each of murder, possession of a firearm by a felon and unlawful possession of ammunition prohibited by prior conviction.

The case stems from the shooting death of Christian Santillan, 22, of Long Beach, who was found with a gunshot wound to the upper body and was pronounced dead at the scene at about 5:40 a.m. Feb. 12 in the 5400 block of Long Beach Boulevard, according to Long Beach police.

“After examining the scene and contacting witnesses, detectives learned a male subject driving a silver van was involved in the murder,” police said in a statement. “Through their thorough investigation, detectives discovered evidence at the scene that enabled them to identify the shooter as 54-year-old Quentin Anderson.”

Detectives located the van registered to Anderson parked on the street in the 900 block of East 109th Street in South Los Angeles, according to police. Detectives said they saw him leave a residence near the van at about 6:45 a.m. Feb. 13, and he was taken into custody without incident.

Anderson has remained behind bars since then.

Police said last month that detectives were still trying to determine the motive for the shooting and the connection between Anderson and the victim.
