Colorado's governor asked the nation Sunday for prayers for Claire Davis, 17, who was critically wounded by a classmate at her suburban Denver high school.

Gov. John Hickenlooper, on CBS's Face the Nation, also credited security procedures adopted after the 1999 massacre at nearby Columbine High School for helping put a quick end to the Arapahoe High shooting by Karl Pierson, 18, who killed himself.

Davis is in critical condition and stable, but she is in a coma, her family said in a statement issued on the hospital's Facebook page Sunday. "The first responders got Claire to the right place, at the right time," the family said. They also praised the care she was receiving and expressed thanks for the outpouring of prayers and support. - AP
