An unknown gunman shot and killed a reporter and videographer for a CBS affiliate in Virginia in a shooting that was being broadcast live this morning. Police are still looking for the suspect, and trying to determine the motive.

Alison Parker, 24, and Adam Ward, 27, a reporter and cameraman respectively for WDBJ-TV, died shortly after 6:45 a.m., said the station’s general manager, Jeff Marks. “We heard screaming and then we heard nothing,” Marks said.

Parker was interviewing Vicki Gardner, executive director of the Smith Mountain Lake Regional Chamber of Commerce, at Bridgewater Plaza in Moneta, Virginia, when the shots were fired. Gardner was shot in the back during the shooting and is in surgery.
