Police Seek Second Man in Deadly Arizona Shootings

Following the shootings outside a Safeway in Tuscon, Arizona on Saturday that killed six and left a US Congresswoman fighting for her life, police investigating the incident have released a photo of a second suspect that they seek to question.

The man, who is described as being white and in his 40s or 50s, was "in the vicinity" of prime suspect Jared Loughner, 22, who was also in the store prior to the shooting. The Pima County Sheriff's Department released the image from Safeway security cameras. Sheriff Clarence Dupnik said at a press conference on Saturday that the man may have been an accomplice.

The man was last seen wearing blue jeans and a dark blue jacket. Police are hoping that Tuscon residents will recognize him and come forward with information.

During the shootings, Congresswoman Gabrielle Giffords was shot in the head. The bullet entered her head near the temple, passing through her brain before exiting through her forehead. She was lucky to have survived the shooting, but is in critical condition and is fight for her life. It is believed to have been the first assassination attempt on a female politician in the US.

In all, six people were killed, including a nine-year-old girl and a federal judge. 12 others were injured.

The suspect, Jared Loughner, is said to have walked calmly up to Giffords and fired at point blank range. He then fired 15 to 20 rounds into the ground before being tackled by two men. He was arrested and is in police custody.

Police say that Loughner had more rounds and believe that the men who tackled him may have saved the lives of even more people. Police said that they were aware of Loughner because he had made death threats in the past, although it was not revealed who he made the threats against.

Giffords, 40, is married to an astronaut, Captain Mark Kelly, who flew to be at her bedside last night.
