2nd Suspect Sought in Arizona Shooting (New York Times):
Representative Gabrielle Giffords, an Arizona Democrat, and 18 others were shot Saturday morning when a gunman opened fire outside a supermarket where Ms. Giffords was meeting with constituents.
A 22-year-old suspect was in custody, law enforcement officials said. But at a Saturday evening news conference, investigators said they were looking for an accomplice who may have helped the gunman.
Six of the victims died. The Pima County sheriff, Clarence W. Dupnik, said among those killed were John M. Roll, the chief judge for the United States District Court for the District of Arizona, and a 9-year-old girl.
At a news conference Saturday evening, Sheriff Dupnik said there was “some reason to believe” that the suspect in custody did not act alone. Officials said they were seeking a second suspect: a 50-year-old, white male.

Another suspect is being sought in the deadly shooting outside a Tucson grocery store Saturday that killed six people and critically wounded a U.S. congresswoman, whom officials say was the target of the attack.
Sheriff Clarence Dupnik said they are not convinced the alleged gunman, who was tackled by “two brave individuals” acted alone in the shooting. U.S. Representative Gabrielle Giffords of Arizona, who was shot in the head, was among at least 19 people shot.
“There’s some reason to believe he came to this location with another individual,” Dupnik said in a news conference Saturday night, adding they have pictures of a second suspect.

The authorities were seen entering the house of someone by that name about 5 miles from the shooting scene, an unincorporated area north of Tucson. The shootings raised questions about potential political motives, though officials did not speculate about what might have provoked the attack. Nevertheless, there were immediate reverberations as Democrats decried the fierce partisan atmosphere in Gifford’s district and top Republicans quickly condemned any outbreaks of violence.
Mark Kimble, an aide to Giffords, said the shooting occurred about 10 a.m., in a small area between an American flag and an Arizona flag. He said he went into the store for coffee, and as he came out the gunman was walking up and started firing.
“Everyone hit the ground,” Kimble said. “It was so shocking. I still can’t believe this happened.”
The gunman wore sunglasses and perhaps a hood of some sort, he said.
The U.S. Capitol Police, which is investigating the shooting, cautioned lawmakers “to take reasonable and prudent precautions regarding their personal security.”
Because of the shootings, House Republicans said they would postpone all legislation that was to be considered on the floor next week, including a vote to repeal the big health care law. Rep. Eric Cantor, Republican of Virginia, and the House majority leader said lawmakers need to “take whatever actions may be necessary in light of today’s tragedy.”
Speaking of Giffords’ condition, Rhee said at a news conference, “I can tell you at this time, I am very optimistic about her recovery.” He added, “We cannot tell what kind of recovery but I’m as optimistic as it can get in this kind of situation.”
At a news conference Saturday evening, Dupnik said there was “some reason to believe” that the suspect in custody did not act alone. Officials said they were seeking a second suspect, a 50-year-old, white male.
The sheriff said the suspected shooter “has kind of a troubled past” and had come to the attention of law enforcement before.
Update: The Pima County Sheriff’s Department has released a surveillance camera photo of the suspect.
