This just happened: I heard a crash at 15th Ave NW and NW Market. A white pickup truck with a canopy sped away northbound on 15th with it's horn stuck on. A few seconds later a police car followed after him.
A minute or two later I hear on the scanner that police have witnessed a truck roll over at 65th and 15th. I can hear the same horn blaring in the background.
Fire is on the way to both accidents. The suspect driver will be tested to see if he or she was driving impaired and will be cited for hit and run.
