Arizona Man Killed During Shootout With Phoenix Police, Officials Say Mario Garnett Involved in Two Previous Bank Robberies

The Arizona man who reportedly organized a Mississippi bank robbery that turned fatal and submitted threats to the president was killed on Saturday while holding up a bank in Phoenix.

Police officers shot and killed 40-year-old Mario Edward Garnett after the robber opened fire on law enforcement officials who'd been called to a Compass Bank location with reports of an armed theft in progress, according to the Associated Press.

Officials who searched Garnett's apartment in Oklahoma City reported they'd discovered information on his computer that indicated plans for an attack, including a list of pistols, ammunition, explosives and rifles to pick up.

Police first received word of a bank robbery on Saturday, when someone called to report they'd seen a man go into a Phoenix Compass Bank wearing a mask, AP reported.

Law enforcement spokesperson James Holmes said that about five people were at the bank at the time of the robbery. The officer who first arrived at the scene spied the assailant exiting the bank carrying a pistol and a bag. The suspected robber then opened fire on police, who shot back.

Garnett was declared dead after he was transported to a medical facility nearby.

The 40-year-old was previously accused of posting violent threats toward President Barack Obama and Israeli Prime Minister Benjamin Netanyahu on the White House's website three years ago. Garnett was also connected to three other crimes, including a Dec. 23 bank robbery attempt in Atlanta, a burglary later the same day in Tupelo, Miss. and the killing of a Tupelo officer.
