Dozens of people were injured, including 10 by gunfire, in a mass shooting on a rush-hour subway train in Brooklyn on Tuesday morning that triggered a manhunt for the gunman.
More than 24 hours later, authorities announced they had apprehended a suspect in the shooting -- 62-year-old Frank James of Philadelphia -- and that federal prosecutors had charged him with a terror-related offense.
In the hours since the incident, hundreds of New York Police Department detectives have been on the case, scouring surveillance footage, interviewing witnesses and tracking leads from evidence left behind at the scene to plot out how the attack unfolded.

Around 2 p.m., James rented a U-Haul in Philadelphia that was later recovered near a subway station in Brooklyn, according to a criminal complaint filed by the Department of Justice. The key to the van and a credit card, which law enforcement sources told ABC News was used to rent the U-Haul, were among the gunman's possessions recovered from the scene of the shooting.

Around 6:17 p.m., James visited a storage facility in Philadelphia, according to the complaint. A receipt for the unit was found in a jacket that James discarded on the subway platform, authorities said.
While executing a search warrant on the unit on April 12, law enforcement agents recovered gun parts and ammo, including "9mm ammunition, a threaded 9mm pistol barrel that allows for a silencer or suppresser to be attached, targets and .223 caliber ammunition, which is used with an AR-15 semi-automatic rifle," the complaint stated.
Agents found more gun parts during a search of James' apartment, on April 12, according to the complaint, including "an empty magazine for a Glock handgun, a taser, a high-capacity rifle magazine and a blue smoke canister."

The U-Haul was captured by surveillance footage driving over the Verrazzano-Narrows Bridge into Brooklyn just after 4 a.m., after crossing state lines from Pennsylvania to New Jersey and then to New York, according to the complaint.

In this still from surveillance video footage which was included in the criminal complaint against Brooklyn subway shooting suspect Frank James, the U-Haul vehicle is shown driving over the Verrazzano-Narrows Bridge into Brooklyn, in the early morning hours of April 12, 2022.
Security cameras captured an individual wearing a yellow hard hat and "orange working jacket" toting a backpack and rolling bag leaving the U-Haul at approximately 6:12 a.m. at West Seventh Street and Kings Highway in Brooklyn, according to the complaint. Police ultimately found the U-Haul nearby on Kings Highway, about three blocks from an N subway stop where James entered the subway system, authorities said.

The shooting unfolded shortly before 8:30 a.m., just as a Manhattan-bound N train approached the 36th Street station in Sunset Park. A man mumbling to himself on the train donned a gas mask and detonated a smoke canister before pulling out a handgun and firing 33 bullets, police said. Ten people, including three teenagers, were shot, authorities said. The hard hat and orange jacket were found at the scene, police said.

James eluded law enforcement by boarding an R train that pulled into the station and traveled one stop before exiting at the 25th Street station, according to NYPD Chief of Detectives James Essig. A surveillance camera recorded a man matching James' driver's license photograph exiting the 25th Street station at approximately 8:40 a.m., according to the complaint.
James was seen again that day at a Park Slope subway stop at 9:15 a.m., Essig said.
Police named James as a person of interest in the investigation later that day.
