State troopers have arrested a man in a hit-and-run accident that killed a construction worker on Interstate 215 on Sunday.

Michael Brinkman, 49, was booked on suspicion of driving the pickup that hit and killed Brayden F. Beddoes, 20, on Sunday in the construction zone in West Valley City.

A witness who claimed to have seen the crash came forward Monday morning, said Utah Highway Patrol Sgt. Jeff Nigbur. The witness said he followed the truck from the scene and wrote down a license plate number, Nigbur said.

Troopers traced the plate number to Brinkman, who lives in Salt Lake County, Nigbur said. An investigator spoke to Brinkman on the phone.

"He did admit to being in Salt Lake area and in the construction zone and he hit something," Nigbur said.

Troopers found Brinkman and his truck in Roosevelt, where he had traveled on Monday for work and took him into custody.

Nigbur said some evidence was found on the truck, but he would not discuss the evidence or whether the truck is damaged.

Beddoes was working for A-Core Construction on I-215 West at 3300 South in West Valley City when he was struck by a southbound truck that went behind a barricade of construction barrels and into the work area, UHP reported.

UHP spokesman Cameron Roden said Beddoes was wearing a reflective vest and was in the far right lane of two lanes that had been closed.

"He had a full lane between him and the active

Beddoes and another worker were sweeping the area after crews had cut concrete, Roden said. The other man was not injured.

After hitting Beddoes, the truck driver hit a concrete barrier and drove about 200 yards before stopping. A construction worker began running toward the truck, and that is when the driver sped away south, Roden said. The witness who called authorities said the truck took a nearby off-ramp and then an on-ramp back to the freeway.

Beddoes was alive when UHP troopers arrived but died before a helicopter could fly him to a hospital.

Brinkman's attorney Jerome Mooney said the details of the incident aren't yet clear.

"Michael is a good guy with no prior record," Mooney said. "We're not sure exactly what happened at this point."
