An East Texan is recovering from a shooting incident at a Dallas railway station. A witness, also from East Texas, says there was little warning before gunfire erupted aboard an Amtrak train preparing to depart Union Station.

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

A Dallas police statement identified the wounded officer as Sr. Cpl. Samuel Hussey, a 22-year veteran of the force assigned to the Dallas Police Department’s Narcotics Division. James Rainey says the innocent bystander, who was shot in the shoulder, was his 29-year-old brother, Paul. The brothers were taking the train to Longview, where they both live. “I’m just very upset and scared, just in fear for my brother, and everything like that, just very shaken up,” said James Rainey. Dallas police believe both Hussey and Rainey will make full recoveries.

Witness Jonathan Beaubien was taking the train home to Mineola. He tells 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 the station resumed after about an hour’s interruption.
