A suspect killed by Phoenix police in a bank robbery attempt is believed to be the same man accused in the shooting death of a Mississippi police officer and the wounding of another, the FBI said Sunday.
The statement came hours after Phoenix police shot and killed a suspect after Saturday's bank robbery attempt. Investigators believe the same suspect also tried to rob a bank in Atlanta on Monday, hours before he allegedly shot the two officers in Tupelo, Miss.
Phoenix police spokesman James Holmes said Sunday that it was unclear when Mario Edward Garnett arrived in the state. He said Garnett was from the Midwest, had served for four years in the U.S. Army and appeared to have no connections to Arizona.
"We have no connection of this young man here in the city of Phoenix or in Arizona," Holmes said at a news conference.
Daniel McMullen, special agent in charge of the FBI's office in Jackson, Miss., said records showed the suspect's cellphone was in Atlanta, Phoenix and Tupelo at the time of each incident.
McMullen also said there were "numerous similarities" between the three bank robberies, including the clothing worn by the suspect, statements he made during the incidents and his "overall modus operandi."
"This investigation is not over," McMullen said at a news conference in Tupelo. "There are numerous leads which we must continue to follow and questions which we must answer."
On Monday afternoon, the suspect stole an undisclosed amount of money from the BancorpSouth in Tupelo before fleeing in a gray sedan, according to McMullen.
Officers Gale Stauffer and Joseph Maher were responding to a bank alarm and a report that the suspect had fled in a white SUV when they spotted such a vehicle stalled in traffic, McMullen said. The officers were confronting the SUV's driver when the suspect exited the sedan, which was stopped behind the SUV, and ambushed the officers, according to McMullen.
Stauffer died and was buried Friday after a funeral attended by as many as 1,000 people. Dozens of uniformed officers from Mississippi, Alabama, Tennessee and elsewhere attended the service.
Stauffer's wife, Beth, said her family was grateful for investigators' work and for the support they've received.
"We can truly begin the healing process, and that could not have happened without the hard work of so very many," she told reporters Sunday. "Gale would be so proud."
Tupelo police Chief Bart Aguirre told the Northeast Mississippi Daily Journal that Maher's condition has improved and he was able to walk some with assistance Friday. Maher moved out of the intensive care unit at North Mississippi Medical Center and into a private room.
The Phoenix shooting happened Saturday morning at a Compass Bank branch in the near-northwest part of the city after someone called 911 to report seeing a man run into the bank while wearing a mask.
There were five people inside the bank during the robbery, Holmes said. A customer who ran outside when Garnett turned his attention to the bank manager also called 911.
The first officer to arrive saw the man leave the bank with a bag and a handgun.
"The officer drew his service weapon and began giving the suspect commands at which time the suspect raised his weapon and began firing at the officer," Holmes said in an earlier statement.
A detective who had just arrived at the scene shot the suspect, who was pronounced dead after being taken to a Phoenix hospital. No officers or bank employees were injured.
Surveillance photos from the attempted bank robbery in Atlanta showed a man wearing a black-and-white patterned jacket tried to rob a Bank of America branch on Piedmont Road around 9:30 a.m. Monday. He was wearing a black ski mask and black gloves and carrying a handgun.
After failing to get any money from a teller, the man demanded and received an undisclosed amount of money from someone who was using an ATM in the bank's lobby. The man was seen leaving in a light gray car with no license plate, possibly a Chrysler 200. Tupelo police believe the man was driving the same car there.
The FBI had offered a reward for information in the case of $100,000, which raised the total reward over $200,000.
Holmes said Garnett drove a rental car to the Phoenix bank. It was unclear where Garnett had been and what he had been doing while in the state.
"We have no idea what he did between the 23rd of December and the 28th of December," he said.
