Knoxville student killed after firing at officers

The gunfire, which erupted at about 3:15 p.m. at Austin-East Magnet High School on the east side of Knoxville, marked the latest in a rash of shootings in the United States since mid-March.

The wounded police officer was struck by a round in the upper leg and was in serious condition following surgery at the University of Tennessee Medical Center, Knoxville police officials said. He was expected to survive.

"He is conscious and in good spirits. ... He's going to be OK. I thanked him for putting his life on the line to protect students and staff at the school. He said he'd rather be hurt than anybody else," Mayor Indya Kincannon told CBS News.

Knoxville police said they responded to Austin-East after getting reports of a gunman at the school and found the suspect in a bathroom.
