An Army Reserve officer killed Tuesday night at a Chesterfield, Virginia, Wawa convenience store was about to celebrate his retirement, his father told the Richmond Times-Dispatch on Wednesday.

Maj. Robert Gooch IV, 34, who had been assigned to Fort Belvoir, was picking up popcorn before a movie night with his teenage daughter when someone opened fire in the Wawa parking lot, his father said.

Gooch’s teenager daughter was unharmed, but the officer died of his wounds at a local hospital, according to a Tuesday release from the Chesterfield Police Department.

Later that night, authorities arrested George Thomas Buschmann after he was stopped for speeding, in a vehicle that matched the description of a silver 2007 Toyota seen driving away from the Wawa after Gooch was shot.

After a chase, authorities found a shotgun and rifle in the car, which had been reported stolen, the Times-Dispatch reported.

Authorities believe Buschmann and Gooch did not exchange words in the parking lot before the shooting. In a jailhouse interview with local news station WTVR, Buschmann said he fired the weapon out of fear for his life.

“Yeah, I feel bad for the situation, but I was trying to protect myself,” he said.

In an interview with WTVR, Buschmann’s sister said that her brother suffered from untreated schizophrenia.
