Once at the residence, police found four victims suffering from gunshot wounds. Jan Jackson, 61, Melissa Jackson, 68, and Sabrina Jackson, 19, were located in different rooms of the home and all pronounced dead at the scene.
The fourth victim, Alexander Jackson, was transported to a local hospital for a gunshot wound to his foot.
Alexander initially called police and said an intruder broke into their home and opened fire. He said this woke him up and he tried to fight off the intruder and was shot in the process.
During the investigation at the home, investigators found no evidence of forced entry and there was no intruder on security camera footage.
