TX: Retired Man Shoots Neighbor who was Tresspassing, exhibiting "Unusual Behavior"

Investigators say the two men had been arguing, though it's not clear over what. There was a physical altercation and, ultimately, the retired officer shot the neighbor.

The victim was shot in the stomach. He was taken to a hospital. The father of the man shot said his son underwent a three-and-a-half hour surgery on Sunday and then had a second surgery on Monday.

Prior to the incident, one neighbor told ABC13, the adult son rang her door bell and later exhibited unusual behavior.
