UPDATED at 9:30 p.m. with identification of victim

A student who was struck by a MetroLink train at a station at the University of Missouri-St. Louis late this afternoon has died of her injuries, officials said.

She was identified by police as Veronica Muo, 27, of the 5800 block of Birchmont Drive in University City.

The accident happened at 5:23 p.m.

The woman was conscious but critically injured as she was airlifted from the UMSL North station, police and Metro spokeswoman Patti Beck said. She was later pronounced dead at a hospital, police said.

Beck said it was unclear why the woman was on the tracks.

St. Louis County Police spokesman Officer Brian Schellman said the woman was crossing the tracks at a crosswalk when she slipped and was struck. The eastbound train was slowing to a stop at the time, he said.
