AUSTIN (KXAN) – Austin Police are investigating a pedestrian fatality on the I-35 service road near Slaughter Lane early Sunday Morning.

A passerby called 9-1-1 after they saw a body on the road. Police responded and found a deceased female.

The driver of the car came back to the scene according to police. APD is investigating the crash.
