Sergeant Patrick Riley was struck and killed while directing traffic in a construction zone at N 64th Street and E University Drive. He was standing in the middle of the intersection with four-way flashing red lights. After waving through a double tractor-trailer to turn left around him, he turned his attention to a car approaching the intersection. His shirt became caught on the fender of the tractor-trailer, dragging him under the dual tires. Sergeant Riley had served with the Maricopa County Sheriff's Office for 12 years.
Survivors
