Leon Deandre Simpson, 39, was shot while driving west on East 50th Street near South San Pedro Street in South Park, Los Angeles, on September 3, 2015. The gunfire caused him to lose control of his SUV; the vehicle hit two parked cars and a home and caught fire. More than 30 firefighters and two LAPD officers pulled him from the burning vehicle, but he was pronounced dead at the hospital at 3:39 p.m.

Simpson was a father of four and the president of a local motorcycle club called Hogg Life. Friends and family described him as a family man who spoke out against violence and was planning to start a youth softball team to give local youngsters positive activities. The Newton Division of the Los Angeles Police Department led the investigation and asked anyone with information to come forward; the motive remained unclear and no arrests or suspects had been identified in the immediate aftermath.

Does anyone who knew Leon or who was in the South Park area that afternoon have information that could help the investigation?
