The widow of a Metro employee who used the transit system to kill himself is suing the agency, saying it did not stop him from jumping in front of a train after he made an earlier attempt the same day.

Yvette Thomas is seeking $1.5 million in her lawsuit transferred to U.S. District Court for the District of Columbia, charging that Metro was negligent in preventing the suicide of her husband Kurtland Johnson — and by extension others — on its property.
