FBI: Cellphone Records Linked Suspect to Robberies 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. Authorities didn't immediately release the suspect's name. 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 grey 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 gray 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. 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. 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. Associated Press writer Michael Kunzelman in New Orleans contributed to this report.
