A homeowner in the San Antonio neighborhood of Knights Cross was shot and killed after an apparent altercation with a door-to-door home security salesman.

According to news reports, 53-year-old homeowner Kerry O’Toole argued with a man who was apparently trying to sell him a home security system before the suspect retrieved a gun from his vehicle and allegedly fired several shots, one of which struck O’Toole in the chest.

The suspect walked to a rec center where he called 911. Police took 35-year-old Richard Luis Amezquita into custody Saturday night and booked him on murder charges. He was released after posting $150,000 bail, according the San Antonio Express-News.

O’Toole died at the scene; no one else was hurt.

A spokesperson said Vivint is still trying to determine the circumstances leading up to the incident, and their thoughts and prayers are with O'Toole's family and neighbors.
