The young Somali-American from Portland stepped off the Green Line trolley at Park Street Over, looking like another of the tens of thousands of students who went through that T station every morning. There were over twenty colleges and universities within two miles of that subway stop, in both Boston and Cambridge. There were a quarter of a million college students in the metropolitan area and it seemed like half of them were on the T headed out for Thanksgiving break.
He wore a backpack over his hoodie, had on a Patriots cap, and kept playing with his iPhone. He moved with the crowd toward Park Street Under and the Red Line trains to Harvard and Braintree. He took the stair that led to the middle platform, where he could get a train in either direction. He started walking behind the staircase to the end of the platform, where there were almost no people waiting. His mission for today was simple. Slip down into the tunnel and check it out for a place where, next time, he could leave his parcel.
A man from South Boston who had just turned eighty-two said to the young Portland man in the hoodie, “Trains don’t stop that far down the platform. Only four-car trains this time a day.”
“Fuck off, granddad,” the young man replied and kept walking, disappearing behind the staircase.
The old man walked in the other direction, to the MBTA police officer who had just stepped out of the train from Ashmont. “The poster says ‘If you see something, say something,’” he said to the officer and then he told him about the student.
As the officer walked around the staircase, he saw the young man holding a video camera and approaching the gate at the top of the ladder down from the platform to the tunnel. “Hey, hold up there,” the officer called out.
The young man in the hoodie started to run toward the ladder. The officer bolted toward him. The student was over the gate and on the ladder before the officer could reach him. The old man, who had slowly followed them, saw both the student and then the officer jump over the gate and climb down into the dark subway tunnel.
In the tunnel, the officer moved quickly on the gravel path by the side of the track, on the opposite side of the railbed from the lethal third rail. As he approached the man in the hoodie, the officer reached out and grabbed the backpack, which came off in his hand. The officer lost his balance, staggering forward. The young man put his hands together and brought them swiftly down on the back of the officer’s neck. The officer fell, hitting his head on the track. He did not get up.
Minutes later the old man saw the lights coming down the tunnel, the Red Line train from Harvard. As the lights grew close, the student climbed back over the gate onto the platform. His backpack was gone, as was his Patriots cap. His hood was hanging behind him. Once over the gate, he began to run up the platform.
“Hey, stop, where’s the cop?” the old man yelled, grabbing onto the student.
The younger man pushed with both hands, knocking the old man down onto the hard concrete platform. “I told you to fuck off,” the young man said as he ran off.
The driver on the Red Line train hit the horn and the brakes when he saw the body on the tracks in the tunnel, just a few meters outside of Park Street Station. When the alarm went off in the MBTA Operations Center at Arborway, the image from the surveillance camera on the platform showed the front car of the train stopped where the emergency brake had brought it to a halt, just inside the entrance to the station.
