Authorities said Sunday that a man who was fatally shot by a Phoenix detective during a bank robbery had been the subject of a massive manhunt after killing one Mississippi police officer and wounding another following a bank robbery last week, reports azcentral.com.

The crime spree Mario Edward Garnett, 40, is suspected of committing began the morning of Dec. 23 in Atlanta, where police said he attempted to rob a bank, failed, and instead robbed a customer at an ATM outside the building.

It continued on the afternoon of Dec. 23, when he robbed a BancorpSouth in Tupelo, Miss., and ambushed two Tupelo officers, killing Officer Kevin "Gale" Stauffer and wounding another officer to make his getaway, authorities said.

It ended just after 10 a.m. Saturday in Phoenix outside the Compass Bank near 34th Avenue and Thomas Road, when a police detective fatally shot Garnett as Garnett was firing at a Phoenix police officer, police said. No officers or bystanders were injured, police said.
