Keith Wayne Needle Matthews was 43 when he was found shot to death on Erie Street in Baton Rouge on January 5, 2013. The killing was investigated as a homicide and produced an early arrest later that year of a suspect named Shingo Edwards.

Prosecutors relied heavily on a single witness, Shaun Hartley, whose testimony was said to be central to the case against Edwards. Before the matter reached trial, Hartley — who had told authorities he feared for his life and was placed in a witness protection program — was found beaten to death in an abandoned house. The loss of the sole witness led to dismissal of the murder charges against Edwards for Matthews’ death.

The two deaths became linked when another person, Jeremy Brown, was later charged with the second-degree murder of Shaun Hartley. Does anyone have information about Matthews, Hartley, or events on Erie Street that night?
