(AP Photo/BancorpSouth via the Mississippi Department of Public Safety) (Newser) – A bank robber sought in two holdups and the murder of a police officer was shot dead yesterday after robbing a bank in Phoenix, according to the FBI. The subject of a nationwide manhunt, he entered a Compass Bank in Phoenix yesterday morning and walked out in a black ski mask, carrying a gun and a bag of money, the Arizona Republic reports. A police officer waiting outside warned him to stop, but the robber allegedly tossed the money in a car and opened fire. A robbery detective who happened to be passing by pulled up and fired on the robber, hitting him in the upper body. The robber died on the scene. "The detective did what he should have done," said a Phoenix police spokesman. "He responded, and because he responded, we have two officers that were involved in this ordeal and they’re both alive." Authorities haven't named the suspect, but say the first two robberies—in Mississippi and Atlanta—seemed similar to the one in Phoenix, the Atlanta Journal-Constitution reports. The suspect allegedly fired at police after robbing a bank in Tupelo, Mississippi, wounding one and killing the other.
