UPDATED at 1:40 p.m. Thursday with identity of victim.

PAGEDALE — A man was shot and killed on a MetroLink train during a dispute at the St. Charles Rock Road train station in Pagedale.

The man was shot just before noon Wednesday, said Metro Transit communications director Patti Beck. The victim was taken to a hospital, where he was later pronounced dead, according to St. Louis County police.

He was identified Thursday as Omar Martin, 23. Police said he lived in the 1600 block of Castle Park Drive in Normandy.

Metro President and CEO Taulby Roach, six months into the job, said on Wednesday afternoon that he was driving out to the shooting himself.

“We need to be accountable for working on these issues as quickly as we can,” Roach said. “I’m, of course, disappointed. I’d prefer we not even have the incident. But I’d ask that the public judge us on our response.”
