U.S. Marshals were conducting surveillance on 24-year-old Hector Karaca on Thursday when he left a motel, went to a mall and stole a car at gunpoint, police said.
Police Sgt. Chris Widmer says Karaca drove off, causing several car accidents before he crashed the stolen Camaro, jumped at least one fence, went into an alley, pulled out a handgun and shot himself in the head.
A police helicopter had followed the stolen vehicle and guided police vehicles.
"It was like the movie "The Fast and the Furious", just hauling butt. The Camaro was at least four car lengths ahead of the cops," Eddie Escalante, the driver of a pickup which collided with the Camaro at the end of the chase, told KVOA-TV.
Karaca was sought in the Oct. 21 killings of 25-year-old Jose Alonso Villa and his 17-year-old girlfriend, Kristen Bianca Furgeri.
They were found dead in a small residence behind a home in midtown Phoenix.
Jordan Tefft, a spokesman for the Marshals Service in Tucson, declined comment on the case.
According to the state Department of Corrections' online profile for Karaca, he was released from the prison system in September after serving time for Pima County convictions for auto theft, attempted auto theft and hindering prosecution.
The profile for Karaca listed numerous violations of prison rules, including rioting, disobeying orders, disorderly conduct, disruptive behavior and smoking.
