Phoenix police fatally shoot suspected cop-killer

(CNN) -- The nationwide manhunt for a suspected bank robber and cop killer may have ended in Phoenix after an officer shot and killed a man following a new bank robbery.

The latest heist took place Saturday morning in Phoenix. After leaving the bank with a bag and gun, the suspect shot at two officers before one of the officers fatally shot him, Phoenix police said. Neither of the officers was injured.

The name of the suspect has not been released.

Authorities believe the suspect's crime spree started across the country nearly a week ago. The FBI said a man tried to rob a bank Monday in Atlanta but failed and ended up robbing a customer at the bank's ATM.

Hours later, authorities believe, the same man robbed a bank about 300 miles away in Tupelo, Mississippi. That robbery escalated to a gunfight with police and the shooting of two officers.

One of those officers, Gale Stauffer, died. Tupelo Police Chief Bart Aguirre said Stauffer's death may be the first in the department's history.

The second officer shot, Joseph Maher, is recovering in a Tupelo hospital.
