Marcus Donté Reed believed that three brothers had stolen his Xbox 360. So he went to their house with an "assault weapon" and shot them all dead.
Donté Reed, aged 33, drove to the Caddo, Louisiana home of the three Adams brothers on Monday night, hid in the woods near their home then gunned them down in their car when they arrived home. He believed that the brothers - 20 year-old Jerimiah, 18 year-old Jarquis and 13 year-old Jean - had broken into the home of his girlfriend earlier that day and stolen his Xbox 360, though he did not report the crime and there is no evidence (as of yet) to suggest the three were involved.
Donté Reed has been charged with three counts of first-degree murder.
