Devian Luevanos, 20

Devian Luevanos, 20, a young black man, was shot in the 700 block of Greenleaf in Compton at about 7:10 p.m. Wednesday, July 11, and died at a local hospital.

He was not a gang member, said Sgt. Steve Katz of the sheriff's homicide bureau. He was simply standing outside with friends when a young Latino man walked up and issued a gang challenge of some kind, provoking an argument. The Latino pulled a gun, shot Luevanos and fled. Luevanos died at Harbor-UCLA Medical Center.

Investigators have released this composite sketch of the killer and are asking for the public's help in identifying and finding him. Anyone with information is asked to call (323) 890-5581 or (323) 890-5578.

Luevanos was shot just a short distance from where Yetunde Price, the older sister of tennis stars Venus and Serena Williams, was killed in 2003, also on Greenleaf.
