According to a neighbor, the gunman shot and wounded his girlfriend, and killed her brother, following an argument. (All three lived together.) He then shot a neighbor who had come to investigate; and soon after that the neighbor's wife, son, granddaughter and a family friend. The neighbor, Kim Dietz, says she sheltered another victim:
Dietz knew all this because another of the man's sons arrived at her home after the shooter chased him through another neighbor's home and shot a child there. The son arrived safely at Dietz's home after wading through a swamp, she said.
The shooter was killed by police.
