A man, now identified as Garrett Foster, was shot and killed in Austin Saturday (July 25) evening after a motorist plowed through a crowd of protestors, ABC7 reports.

According to police, the incident occurred at about 9:50 p.m. on Fourth Street and Congress Avenue blocks away from the Texas state capitol. Witnesses say the driver honked, turned down Congress, and then bulldozed through the crowd.

Foster, who was licensed to carry, was reportedly carrying an AK-47 when he approached the vehicle. The man driving the vehicle then allegedly fired multiple shots with three of the bullets striking the victim.

There were other protesters on the scene with rifles who fired shots at the man’s car as he sped off. One witness on the scene, Hiram Gilberto, caught everything on his Facebook live stream. In the video, the march appears to be relatively peaceful until loud honking is heard followed by a succession of shots and curdled screams.

CPR was performed on Foster by EMS. He later passed away at Dell Seton Medical Center.

Police have taken the alleged shooter into custody and are investigating the occurrence as a homicide. Authorities say the suspect is cooperating.

Foster’s mother, Sheila Foster, made an appearance on “Good Morning America” on Sunday (July 26) and says her son was a regular at these protests along with his fiancée Whitney Mitchell, who he’d have to push in a wheelchair because she is a quadruple amputee.

His mom claims her son was pushing Mitchell’s wheelchair moments before he was shot. Mitchell was not injured during the shooting.

“He was doing it because he feels really strongly about justice and he’s very heavily against police brutality, and he wanted to support his fiancée,” Mrs. Foster told “GMA.”

On Sunday (July 26) morning, around 50 protesters gathered around Austin Police Department headquarters in protest.

A GoFundMe page has been set up to help raise money for Mr. Foster’s funeral expenses. So far, over $50,000 has been donated from supporters.
