SAN TAN VALLEY, Ariz. -- The Pinal County Sheriff's Office is searching for the driver in a hit-and-run collision that seriously injured two people Saturday.
The sheriff's office said that about 3:15 p.m., a 2004 Dodge pickup truck traveling south on Gary Road ran the red light at Hunt Highway and caused a chain-reaction crash.
The pickup truck reportedly struck the passenger side of a 2007 Infinity sedan traveling west on Hunt Highway, which then collided with a 2007 Toyota SUV.
The sheriff's office said the 43-year-old male driver and 48-year-old female passenger in the Infinity sedan, both Coolidge residents, were taken to a hospital with serious injuries. The man was transported by ground ambulance and the woman was airlifted.
The occupants of the Toyota SUV did not report injuries.
The driver of the truck reportedly fled on foot.
The sheriff's office said there were open cans of beer in the center console of the pickup truck and open cases in the cab.
"There is little doubt this collision was alcohol-related," Pinal County Sheriff Paul Babeu said in a statement. "Through fingerprints and other evidence left at the scene, there is little doubt the driver will soon be identified and then arrested. The driver may have felt he would avoid criminal charges by running but instead he will now face additional charges."
Detectives from the sheriff's Vehicular Crimes Unit are investigating and following up on possible leads.
Anyone with information is asked to call 520-866-5111.
