Gabrielle Giffords Recovery; Second Man Over US Shooting Spree


Security camera image from video shows an individual the Pima County Arizona Sheriff's department is trying to identify that was seen at the location of the shooting of Rep. Gabrielle Giffords.

US police have released an image of a second suspect after a shooting spree that left six dead and a congresswoman seriously injured.

Doctors treating Arizona Rep. Gabrielle Giffords said Sunday that she is able to respond to simple commands.

""We are very encouraged by that,"" said Dr. Michael Lemole, Jr., chief of neurosurgery at the University Medical Center in Tuscon, Arizona. ""I am cautiously optimistic.""

Giffords, who was shot in the head at point blank range during a voter meet-and-greet remains in critical condition and is so far unable to speak.

Giffords and another 18 people were caught in the fusillade after a cold-blooded killer opened fire without warning outside a Tucson grocery store on a sunny weekend morning.

A 9-year-old girl, who was the granddaughter of former Yankees and Mets manger Dallas Green, a federal judge and a Giffords staffer were among those killed. Giffords and 12 others where wounded in a shooting that shook the nation.

""This is more than a tragedy for those involved,"" said President Obama. ""It is a tragedy for Arizona and a tragedy for our entire country.""

The suspect - identified as Jared Loughner, 22 - marched up to Giffords about 10 a.m. local time as she spoke to a couple, aimed his handgun and fired from just a few feet away.

Authorities are also searching for a second suspect and released a surveillance photo of a white man in his 40s or 50s with dark hair on Sunday.

Giffords, 40, had a bullet pass completely through her skull before she collapsed in front of her horrified constituents."
