Rodney Burke, 48, was found in his Trenton, New Jersey, apartment in the early morning of November 4, 2014, suffering multiple gunshot wounds. He was taken to a local hospital but died of his injuries. Diagnosed with schizophrenia at 18, Burke had been repeatedly targeted by local criminals who stole his disability checks, and investigators say a robbery plot against him escalated into violence.

Authorities determined four people conspired to rob Burke; one of the assailants shot him. In the weeks and months after the killing, three suspects were arrested and later pleaded guilty: Jaquan Dallas, identified as the shooter, to aggravated manslaughter; Alexandria Gomez, to aggravated manslaughter; and Kenneth Hines, to armed robbery. A fourth person believed to have taken part in the plot has not been identified or captured.

Does anyone have information about the unidentified fourth person or memories of Burke in Trenton that could help fill gaps in the case?
