From the article:

"It all started when a suspect speeding away from police in a pickup truck on a local highway smashed head-on into a truck driver, as local media reported. Medics sedated the truck driver, who was severely burned, and took him to the University of Utah Hospital. He arrived in a comatose state, according to the Deseret News. The suspect died in the crash."

In other words the truck driver was the victim, the suspect, who was fleeing police and slammed head on into the truck driver, died in the crash.
