Family of man shot, killed by Gilbert police say he had PTSD

Gilbert police said Brett Shanahan was wearing a ballistic vest and had a handgun and a rifle when he was shot.

GILBERT, Ariz. — The family of the man who was shot and killed by Gilbert police after allegedly making threats toward them with guns said he had PTSD.

40-year-old Brett Shanahan was "a great father and friend," a family member told 12News. 

The Gilbert Police Department said the shooting happened on Sunday at around 2 p.m. when officers were responding to a report of a person with a gun.

When officers arrived, they did not initially find the suspect — later identified as Shanahan. 

“It all kind of happened really, really fast," Lorelei Barker, a neighbor, said. “One of the officers came to ask us some questions and then the next thing we knew there was a flurry of activity."

Shanahan drove into the neighborhood near Greenfield and Knox roads, just east of Crossroads District Park. Shanahan got out of his vehicle wearing a ballistic vest while carrying both a handgun and a rifle, police said.

"I saw the truck pull up in the middle of the road and I saw about 4 police officers open fire," Ryan Bartman, a neighbor, said.

Shanahan was shot as he approached the responding police officers and made threats toward them, according to police. Officers ordered Shanahan to stop but he ignored the commands issued by officers, police said.

“You can tell that the way that he drove up that he was aggressive," Bartman said. "I heard it skid out, and you can tell by the way it’s parked that it’s like you know sideways in the middle of the street.”

There were no injuries to members of the public or officers during the incident, according to police.

Witnesses told 12News they heard between 10 to 15 gunshots.

“Real quick, like almost like lighting off firecrackers. I mean it was quick," Clay Crohn said.
