Joel David Leach, a 28-year-old man from Los Angeles, was shot to death on May 1, 2010, in the early morning at an apartment on North Alexandria Street in East Hollywood. The Los Angeles County coroner’s records list a fatal gunshot wound to the face; Leach was pronounced dead at the scene.

A 45-year-old man, Ronald Henderson, called police about 2:05 a.m., reporting he had shot a friend at his apartment. Henderson admitted to the shooting and was arrested on suspicion of murder; he was held at Men’s Central Jail with bail set at $1 million. The district attorney sent the case back for further investigation and delayed filing charges, and Henderson was released on May 4, 2010, while detectives continued evidence collection. Investigators said they believed a third person had been present and were searching for that witness to corroborate or refute Henderson’s claim of self-defense.
