Image of 2nd Shooting Suspect Released

Arizona Authorities Seek Help in Identifying Man Seen at Shooting Rampage

(CBS/AP) TUCSON - Authorities have released an image of a second man possibly involved in the shooting rampage that left 19 people wounded, 6 fatally.

The Pima County Sheriff's Department early Sunday morning released an image of a man seen at the location, possibly associated with the suspect. He is described as a Caucasian male, approximately 40-50 years old, dark hair and was last seen wearing blue jeans and a dark blue jacket

Authorities were investigating the possibility that the suspect who killed six people and wounded 13 more outside a Tucson grocery story, including U.S. Rep. Gabrielle Giffords, did not act alone.

Anyone who knows the identity of this individual is asked to contact 911, 88-CRIME or the Federal Bureau of Investigation at (520) 791-6974.

Earlier at a press conference Saturday night,Pima County Sheriff Clarence Dupnik said a 22-year-old was in custody after the shooting rampage. He would not identify the suspect, but people familiar with the investigation said he was Jared Loughner.

Officials say he has claimed sole responsibility for the attack, but said authorities were "not convinced he acted alone," Dupnik said.

Dupnik said authorities had "some reason to believe he came to the event with another individual," and said investigators had pictures of the other "person of interest." Dupnik would say the person appeared to be around 50 years old.

Giffords, D-Ariz., was shot in the head in an area where the lawmaker was meeting with constituents. Sheriff Dupnik said authorities believe she was the target and that there was no security at the event.

The shooting rampage claimed six lives, including a 9-year-old child and U.S. District Judge John Roll, officials said. Thirteen more were wounded at the scene, including Giffords. Five were listed in critical condition and five were in serious condition. All had come out of surgery by Saturday evening.
