The man arrested Wednesday in the shooting of 10 people on a Brooklyn subway was charged with a federal terrorism offense, a day after the attack on a crowded rush-hour train.
That key led investigators to James, a New York City-area native who had more recent addresses in Philadelphia and Wisconsin.
Investigators believe James drove up from Philadelphia on Monday and have reviewed surveillance video showing a man matching his physical description coming out of the van early Tuesday morning, the official said. Other video shows James entering a subway station in Brooklyn with a large bag, the official said.
In one video, posted a day before the attack, James, who is Black, criticizes crime against Black people and says drastic action is needed. Police Commissioner Keechant Sewell called the posts “concerning" and officials tightened security for Adams, who was already isolating following a positive COVID-19 test Sunday.
