ROANOKE, Va. — A day after two journalists were slain on live television, their colleagues at a Virginia morning newscast returned to the air with memories, tears and a determination to carry on the victims’ dedication to the news.

The emotional crescendo of WDBJ-TV’s “Mornin’” show on Thursday came when two anchors and a weatherman joined hands to mark a moment of silence at 6:45 a.m., 24 hours after the shooting.

“We are approaching a moment that none of us will ever forget,” said anchor Kim McBroom, her voice faltering. Pictures of reporter Alison Parker and cameraman Adam Ward were displayed while the show went silent.

On-camera, the team kept their composure through tears.

“I don’t know how to do the weather on a day like this,” weatherman Leo Hirsbrunner said.

McBroom told him: “Good job, partner. We’re going to get through this together.”

Their struggle was even more visible inside the studio during commercial breaks. Hirsbrunner dabbed his eyes, tried to wave away tears and at one point bent down with his hands on his knees to gather himself off-camera.
