At 1:17am a Commerce City PD unit attempted to stop a dully pickup pulling a flat bead trailer with a piece of heavy machinery on it pulling out of Reunion at 104th near Tower Rd. The vehicle failed to yield and headed W/B 104th. The watch commander then asked what the reason for the stop was. The officer advised that it was traffic and the fact that he was pulling out of a construction site in the middle of the night. The watch commander advised the officer to discontinue the pursuit. The officer then began to follow from a distance. The suspect was halted by a train at 104th and Hwy 85. The suspect pulled in to a business parking lot, blacked out, and went to turn around. When the suspect pulled out he attempted to ram the perusing officer. The pursuit was then re-initiated. The vehicle traveled at speeds no greater then 50 mph back to Hwy 2, then north to sable. At sable Blvd the suspect went eastbound on to I-76. Stops sticks were deployed along the way by the officers that went north on Hwy 85 to get around the train. At around 128th Ave the vehicle crossed over the median and continued eastbound in the westbound lanes. When the watch commander was finally able to get on the radio he ordered the pursuit terminated again. By this point the suspect vehicle was just west of 136th Ave. At that point the suspect went off to the left side of the highway. The next radio traffic was shots fired. Chopper go!! For some reason they had to extricate him out of the truck. Not sure what happened with the truck. It was still upright when it came to a stop. The guy had two warrants at the time.
