AUSTIN, Texas — Two teenage suspects are in custody Sunday evening after at least 12 shootings across Austin that left four people injured, authorities said. A third person who fled the scene remains at large in the Manor area.

Austin Police Chief Lisa Davis identified the two suspects in custody as a 15-year-old and a 17-year-old.

The 17-year-old had an existing warrant for the theft of a firearm from the same store where the 15-year-old had stolen a gun from Saturday. Davis said both firearms used in the shootings were stolen.

The suspects are being taken to juvenile detention, and Davis said investigators are not yet interviewing them.

A third person ran from the vehicle when Manor police and Travis County Sheriff’s Office deputies stopped the white Kia Optima, but Davis said investigators believe the two suspects already in custody are the individuals captured on surveillance video.

Manor Police Chief Ryan Phipps said his officers spotted the suspect vehicle traveling in the opposite direction.

Officers pursued the vehicle through Old Town Manor before moving onto northbound FM 973, where the suspects attempted to cut through a field where the vehicle crashed.

All three suspects fled on foot. Two were quickly apprehended and the third remains at large.

Phipps said the search area is large, spanning multiple neighborhoods, and authorities are deploying helicopters and drones to locate the third individual. The shelter-in-place order remains in effect for areas around Ralph Ritchie Road and Suncrest Road, North FM 973 near Suncrest Road and Tower Road, and the Presidential Meadows, Greenbury and Stonewater subdivisions.

Mayor Kirk Watson and Chief Davis addressed reporters at an evening press conference, where Watson praised the multi-agency response. Watson said he had also been in contact with Manor Mayor Christopher Harvey and Governor Greg Abbott, who extended his support to the city.

The spree began late Saturday afternoon, with the first calls coming in around 3:45 p.m. Saturday, Davis said. The first shooting happened in the 6700 block of Wentworth Drive in east Austin, where the suspect fired toward Fire Station 26.

The shootings paused overnight before resuming Sunday morning at 8:47 a.m., when a man walking his dog was shot in the back near the intersection of Janes Ranch Road and Ballydawn Drive in southeast Austin. Police then began connecting the incidents.

Another shooting happened in the 2800 block of Montebello Road in southwest Austin near Rollingwood, where the suspect fired toward Fire Station 32.

An additional shooting near the intersection of Burton Drive and Oltorf Street is also under investigation. One person was shot and transported to South Austin Hospital, where they were in surgery as of Sunday.

Across the 12 incidents, the suspects fired at two separate fire stations. At one of those stations, a fire truck was struck while firefighters were standing directly behind it.

The suspects also fired into multiple apartment buildings, prompting officers to go door to door to check on residents. A pole camera captured one of the shootings on video, showing the suspects firing from a vehicle at a woman standing outside a store.

The suspects stole at least four vehicles during the spree. Davis said the constantly changing vehicles, combined with the spread of the incidents across South Austin, made it difficult in the early hours to connect the calls. She acknowledged that license plate reader technology could have aided the investigation, and both she and Mayor Watson said they are open to revisiting the city’s policies on that technology going forward.

In total, four people were shot. Austin Travis County EMS Chief Rob Luckridge said three victims sustained non-life-threatening injuries and one was critically injured and received whole blood treatment on scene before being transported to a local trauma center. All four were taken to local trauma centers.

Davis said she had no clear motive for the shootings.

“I don’t know what motive would drive anybody to come and drive around senselessly in this city and shoot,” she said.
