Texas Amtrak shooting leaves 1 dead

DALLAS - A witness says there was little warning before gunfire erupted aboard an Amtrak train preparing to depart Union Station in Dallas.

A gunman is dead and an off-duty police officer and bystander were wounded after a 3:40 p.m. Monday exchange of gunfire aboard the Texas Eagle heading from San Antonio to Chicago.

Witness Jonathan Beaubien was taking the train home to the East Texas town of Mineola. He tells CBS affiliate KTVT-TV of Dallas and Fort Worth that he was about five rows behind the shooting. He said it happened quickly, and he saw few signs of an altercation or confrontation before the shooting started.

Dallas Area Rapid Transit train service through to and front the station has resumed after about an hour's interruption.
