A man was killed on Monday afternoon after he was struck by an inbound Braintree train at JFK-UMass station. An eyewitness at the scene told the Reporter that he saw an adult male jump in front of the train. MBTA Transit Police say that foul play "is not suspected."

Boston firefighters were called to the MBTA station at 2:38 p.m., according to Boston Firefighter Steve MacDonald. The chief who responded to the scene quickly determined that a "recovery operation" was needed— an early indication that the person was deceased.

MBTA Transit Police interviewed apparent witnesses inside the station. One man, who was himself taken away from the scene in an ambulance, told the Reporter he saw the man jump in front of the train.

"He crossed his hands over his chest and just jumped in front of the train, and then you couldn’t see him," he said.”

As police and fire officials teemed through the station, hundreds of commuters— many of them students— crowded downstairs to board shuttle buses that replaced trains on the Braintree line. Service continued on the Ashmont side of the tracks for most of the operation and yellow police tape prevented commuters from walking to the Braintree side of the station. However, the station's turnstile concourse was completely sealed off for about ten minutes when the man's body was removed by firefighters at 3:40 p.m.

Access to the commuter rail platform was also sealed off to commuters for about one hour as the recovery work went on behind a white sheet that firefighters attached to a fence next to the scene.
