A stabbing at the 24th Street Mission station left one person dead. The incident happened on the street-level plaza above the station.
BART says a surveillance camera shows two men arguing near the elevator at the station around 1:40 p.m. when one man stabbed the other. The victim tried to walk down to the station but collapsed on the platform.
The suspect fled the area, and authorities are now looking for them. No details were provided about a suspect description.
