Police say a Metromover car rolled over and killed a station supervisor as he inspected the tracks.
The accident happened Saturday. The computerized vehicle, which is not driven by a conductor, was stopped, but moved forward for an unknown reason.
Police found the body about 100 feet from the platform; the identity of the supervisor wasn't released.
This is the second public transit worker death in the last week. On Sunday night, a 60-year-old Metrorail security officer was shot and killed by two men in a station garage.
