The man charged with killing a Virginia State trooper told investigators that God made him do it, according to media reports that cited court documents.

Russell Brown, 28, is accused of shooting and killing Master Trooper Junius Walker in Dinwiddie County last week and exchanging gunfire with another trooper who responded to the incident. He is charged with capital murder, attempted capital murder and two counts of using a firearm during a felony.

Brown's grandmother told police that in the weeks leading up to the shooting, Brown uncharacteristically talked about the Bible. The Richmond Times-Dispatch reported that the manager at the apartment complex where Brown lived told investigators that Brown hadn't been acting like himself recently.

When police interviewed Brown after his arrest, he told them that he knew the trooper's killing would happen because he was instructed to do it by God. He also said that a Virginia State Police special agent who was interviewing him would be the next to be killed.
