Antwain Elisha Henderson was 34 when he was shot to death in the early morning hours of August 31, 2011, in the 5800 block of Field Place NE in Washington, D.C. After the shooting his body was placed in the trunk of his own car, which was driven to the 800 block of Balsamtree Place in Fairmount Heights, Maryland, and set on fire. Firefighters found his badly burned remains; the medical examiner ruled the cause of death a gunshot wound to the head.

Investigators arrested several people in connection with the killing. Sean Donnelle Hawkins told police an argument happened before Henderson was shot and said another man fired the fatal shot; Hawkins also admitted taking a handgun from Henderson’s waistband after the shooting and described moving the body into a nearby residence with two other men before placing Henderson in trash bags and putting him in the car.

Prosecutors later failed to disclose that a witness had heard Henderson threaten to kill Campbell and that Henderson had been angry with Campbell for acting as a government witness in an earlier case. That Brady disclosure failure affected the defense’s ability to argue self-defense and led to Campbell’s release to a halfway house after more than five years in custody. Does anyone have information about Henderson’s final hours or the movements of his car on August 31, 2011?
