CHICOPEE, Mass. (AP) — State police say a 20-year-old Springfield man fleeing a traffic stop has died after rolling his SUV on an Interstate 391 ramp in Chicopee.

Police say a trooper on routine patrol was passed by a speeding SUV on I-391 south just after midnight Wednesday.

The trooper turned on his flashing lights and pulled over the SUV at the bottom of a ramp. As the trooper approached, the driver took off, and got on I-391 north.

The trooper followed, saw a plume of smoke, and saw the SUV rolled over at the bottom of a ramp. The driver, Jackson Rosario, had been ejected. He was declared dead at a hospital at about 2 a.m.

Police found a replica handgun and a large amount of cash in the vehicle.
