Man kills mother’s friend for making pass at his imaginary girlfriend

A mentally ill man in Florida who died after a gunfight with police had just gunned down his mother’s friend for making a move on his imaginary girlfriend, authorities said.

Brian Desario, 30, walked into the garage of a home where his mother, her boyfriend, and another friend were hanging out and accused a man, identified as 56-year-old David Armstrong, of flirting with his girlfriend. He then fatally shot Armstrong, went inside the home and came back out to shoot Armstrong again.

Pasco County Sheriff Chris Nocco said that Desario suffered from mental illness.

“The suspect believed that the mom’s friend; who is the victim in this case, was trying to pick up Brian’s girlfriend and hit on Brian’s girlfriend,” Nocco said. “Please note, Brian does not have a girlfriend. In his mind he did. But, in reality, he didn’t.”

DiSario’s mother and her boyfriend fled to a neighbor’s house and DiSario headed to Gulf Island Drive, where cops found him standing in the middle of the street.

Following the shooting, Desario began walking toward the nearby Gulf Highlands Elementary School, pointing his gun at the building. The school was immediately put on lockdown, and no children were harmed. When police arrived, Desario opened fire on two deputies, initiating a 10-minute shootout, during which he was killed.

A sheriff’s office robot later found DiSario’s body, WTSP reports. It was not clear if he killed himself or died of shots fired by police, none of whom were injured during the gunfight.

Armstrong’s body was found inside the garage. He pronounced dead at the scene.

Police said Desario had a stockpile of guns and ammo and they are investigating to determine where he got the weapons.
