Small said someone rifled through drawers in a second bedroom and there was fresh damage to a closet door.

“It definitely appears that at least one of the rooms was ransacked and the fact that this victim was shot in the head is suspicious enough for this to be investigated as a homicide at this time,” he said.

Police aren’t sure if anything was taken. They also towed a red Camaro from the scene.
