Miguel De Jesus Castro, a 20-year-old Latino, was shot on the evening of September 26, 2016, in the 13500 block of Lakeland Road in South Whittier. Coroner’s records list the cause of death as a gunshot wound. Castro was visiting a friend at that address when an argument broke out at about 10:50 p.m.; during the altercation, Jorge Nicolas Arellano Lopez allegedly pulled out a gun and shot Castro in the driveway. Castro was transported to UC Irvine Medical Center in Orange and was pronounced dead the next morning at 3:23 a.m.

Jorge Nicolas Arellano Lopez, 23, was arrested the same evening. He was charged with murder and assault with a semiautomatic firearm on September 28, 2016, and pleaded not guilty. The Los Angeles County Sheriff’s Department Homicide Bureau handled the investigation and asked anyone with information to contact Crime Stoppers.
