Affidavit: Drive-by shooting led to lockdown at Dell Seton

AUSTIN (KXAN) — At least two people, including a teenager, were charged with a Friday night drive-by shooting that led to a lockdown at Dell Seton Medical Center after the suspects rushed into the hospital.

Mario Suaste, 20, is charged with evasion of arrest, a third-degree felony, a court document said. He was booked into the Travis County Jail Friday night, online jail records showed. No attorney was listed for him at the time this article was published.

According to Suaste’s affidavit, police believe he was driving a black car involved in the drive-by shooting and ran away from police.

There were two other passengers in the car with Suaste, including a 17-year-old charged with aggravated assault with a deadly weapon, according to a separate affidavit. Police believe the 17-year-old pointed a gun at another car and fired shots.

The affidavits said two people in a white car told police that the black car followed them “a very short distance” from a gas station near Interstate 35 and US 290 to I-35 service road and then to East 53rd. 1/2 st. The black car pulled up to the left of the white car, and as the cars lined up side by side, both sides rolled down their windows.

Words were exchanged between the white car and the black car. Then shots were fired, the affidavits said. A victim in the white car told police that at least six shots were heard to the head, and the second victim said they saw the front passenger of the black car point a gun at their car, the affidavit said.

Several police cars turned on their lights and began following the black car as it pulled away from the white car, according to the affidavit.

An officer in an unmarked police SUV chased the black car, which made its way to Airport Boulevard, the affidavit said. During the chase, the black car reached speeds of over 90 miles per hour and ran a red light. That officer eventually lost sight of the black car after coming into an I-35 driveway.

The APD Air Unit monitored the black car and the three suspects from above. According to the affidavit, the unit saw the three suspects run out of their car near the Frank Erwin Center and into Red River Street.

The same officer in the SUV arrived at the scene and saw the suspects enter the east entrance of the Dell Seton Medical Center. The affidavit said more APD officers responded to the hospital and hospital security was alerted. Video surveillance was used to keep an eye on the suspects while the hospital was closed.

According to the affidavit, officers found the three suspects, including Suaste and the 17-year-old, hiding under a stairwell on the ground floor. One of the suspects told police that Suaste was driving the black car, and he initially drew the gun. The firearm was found hidden in the fire suppression system in a stairwell of the hospital.

Video surveillance from the gas station and hospital identified the 17-year-old as the one who sat in the front passenger seat of the black car, and Suaste as the one who took the driver’s seat.

KXAN has reached out to APD to ask if the third suspect will be charged. We will update this story as more details are released.
