Road rage might have led to a deadly hit-and-run Saturday in Southeast Austin, police said.

Eric Walz, 33, was driving at the intersection of South Pleasant Valley Road and Stassney Lane when he exited his vehicle at 10:40 a.m. and approached another driver, police said. Police did not say why Walz stepped out of his car.

The other driver then struck Walz and accelerated, launching Walz over the hood of the car, police said. The driver — who did not call police — left the scene, leaving Walz on the ground, police said.

Walz was hospitalized, and he was declared brain dead at 7:02 a.m. Sunday, police said.

At 6 p.m. Tuesday, police said they tracked down the suspect, but did not release further details.

"The investigation continues, and detectives will consult with the district attorney's office," Austin police said in a statement.
