Pima County sheriff releases a photo of an additional person sought for questioning in the Arizona shooting that killed 6 and wounded 13, including Rep. Gabrielle Giffords.
The Pima County sheriff's office released a photo of a man they described as a person of interest who was wanted in connection with Saturday's shooting, which left 13 wounded, including Democratic Rep. Giffords, 40. The unknown person was photographed by a surveillance camera near the shooting suspect, Jared Lee Loughner, 22.
The person appears to be white with dark hair and about 40 years old.
"We want to know if the person of interest is associated with" the suspect, Pima County Deputy Jason Ogan said in a telephone interview. "We released the photo to see if anyone knows him."
The suspect was in federal custody Sunday, Ogan said. On the orders of President Obama, FBI Director Robert Mueller traveled to Arizona to head the investigation.
Loughner was apprehended by people in the crowd after the midmorning shooting at a Tucson supermarket. Witnesses described how he sprayed the area with bullets, killing among others, Arizona's chief federal judge and a 9-year-old girl, who was later identified as the daughter of a Dodgers scout.
Officials wouldn't discuss the motive for the attack, but witnesses said it appeared focused.
"I feel like he knew what he came there to do and he done it," Joe Zamudio said Sunday morning on MSNBC.
Authorities identified the dead as U.S. District Judge John Roll, 63; Christina Taylor Green, 9; Giffords aide Gabe Zimmerman, 30; Dorothy Morris, 76; Dorwin Stoddard, 76; and Phyllis Scheck, 79. Roll had just stopped by to see his friend Giffords after attending Mass. (Continues...)
