Metro Police are investigating a fatal crash involving an off-duty IMPD officer on the city's near northwest side Friday afternoon.

Listen:

Officers were called to the intersection of W. 29th St. and N. Harding St. on a report of a crash with possible entrapment. When they arrived, they found a white Lincoln which had suffered extensive damage. Its driver, 78-year-old William Wilkins of Greenwood, was transported to IU Health Methodist Hospital where he later died. Wilkins' wife, who was a passenger in the car, was also taken to the hospital with non-life-threatening injuries.

Investigators believe Wilkins was traveling northbound on Harding when he ran a stop sign and collided with a red jeep driven by 38-year-old IMPD officer Scott Aurs. Aurs and his young son were not seriously injured in the crash. IMPD Officer Kendale Adams says there was only a stop sign for traffic on Harding Street and the intersection had a working traffic signal with flashing red and yellow lights.

A voluntary blood draw was taken from Aurs which is standard procedure for a fatal crash. Aurs is a 13-year veteran of IMPD.
