TEMPE, Ariz. (AP) -- Authorities say a suspect has been arrested in a fatal hit-and-run accident in Tempe last week.
Tempe police say 23-year-old Keenan Williams is being held on suspicion of leaving the scene of a fatal accident, aggravated assault and two counts of endangerment.
He's been booked into Tempe City Jail but police didn't immediately know Monday if Williams has an attorney.
Police say the U-Haul pickup truck Williams allegedly was driving Thursday rear-ended a vehicle in which 60-year-old Ruben Montalbo was a front-seat passenger.
That started a chain-reaction crash that left Montalbo with serious injuries. He was taken to a hospital and later died.
"It's a very difficult situation...The injuries were pretty serious right off the bat," said Sgt. Steven Carbajal with the Phoenix Police Department. "They were waiting for some family and friends to get into town to say their final goodbyes but unfortunately they didn't' have that opportunity because he passed away before that."
Police say Williams fled the accident scene on foot and was located Saturday by Tempe police detectives and taken into custody.
According to court documents, police were able to find Williams because the truck was rented by his sister. She was using it to move into a new apartment.
