Two people have been charged in connection with the death of a McDonough man who was shot in the head Sunday.

Joseph Franklin Norris, 49, and Tonia Lynn Gantt, 44, planned to rob Michael Raymond Patton, 45, according to police, but something went wrong and Patton ended up getting shot, Henry County police say. Norris and Gantt have been arrested on charges of murder and are being held in the Henry County jail, according to Sgt. Joey Smith, county police spokesman.

Police say certain details cannot be released to preserve the integrity of the case, but they do know Patton and Gantt lived together in the 100 block of Highland Drive in McDonough. An emergency call directing officers to their residence was received about 2 a.m. Sunday, according to a news release. At the residence, police found Gantt with a head wound and Patton dead.

It is believed that Gantt conspired with Norris to rob Patton, Smith said. At some point, there was gunfire, which resulted in Patton's death, he said.

The incident was investigated by law enforcement from Henry and Butts counties, Smith said.

In addition to facing murder charges, Gantt was also charged with possession of methamphetamine with the intent to distribute.
