GREELEY, Colo. -- The Greeley Police Department believes road rage is to blame for a deadly crash Tuesday morning. The victim was identified Wednesday night as 33-year-old Alberto Ruiz Jr. of Greeley.
Witnesses said a driver was forced into a concrete wall in the 3000 block of West 29th Street about 11 a.m. Officers are searching for a suspect.
Pictures from the crime scene showed detectives removing bloody evidence from the victim's pickup truck.
"He had injuries that were consistent with the traffic accident," Lt. Adam Turk said.
Employees at nearby businesses in the south Greeley neighborhood said they heard a loud bang before the truck hit a wall.
"We have witnesses that have reported some type of road rage incident between another vehicle," Turk said.
How the deadly rage started is unclear. Witnesses said another pickup truck sped away after the collision.
Police have released a picture of what they said is the suspect's truck -- described as a tan or gold Chevrolet.
"We're canvassing businesses in the area with possible surveillance footage," Turk said.
Police, early in the investigation, won't say if the victim was shot or ran off the road.
Witnesses said an off-duty EMT, working at the Harley Davidson dealership across the street, was the first responder to the scene. Co-workers said the EMT returned to work covered in blood.
The victim's identity has not been released, but a witness said he appeared to be a Hispanic man in his 30s.
