St. Louis County police have identified the man fatally shot at a MetroLink light rail station. Police on Thursday identified the victim as 23-year-old Omar Martin. The search continues for the shooter. Police Sgt. Benjamin Granda says the shooting happened Wednesday in Pagedale. Granda says the gunman and Martin were involved in a dispute on a train. Once the train stopped at the St. Charles Rock Road station, Martin was shot and the gunman ran. In August, 48-year-old Craig LeFebvre was hit and killed by a stray bullet near a MetroLink station. Earlier this month, 12 people were indicted for a series of violent crimes at MetroLink stations, including the killing of LeFebvre.
