DES MOINES, Iowa (AP) – The man who led police on a vehicle chase through Ames city streets to Iowa State University and was shot and killed by an officer has been identified.  Ames police say 19-year-old Tyler Comstock, of Boone, died at an Ames hospital Monday.

Police spokesman Geoff Huff says Comstock had become upset and took his father’s pickup. He ignored attempts by police to pull him over and led several officers on a chase sending pedestrians scrambling to get out of the way. The pickup ended up on the university campus and crashed into a tree. Police say Comstock continued to rev the pickup’s engine, ignoring officers’ commands to off the engine.

Officer Adam McPherson, an Ames officer for 8 1/2 years, fired six rounds at the pickup, striking Comstock at least once.
