Law enforcement officials said they were searching for 62-year-old Frank R. James, of Philadelphia, Pennsylvania.
10 people were shot and another 13 were injured on the subway in Brooklyn Tuesday morning when a gunman set off smoke bombs and began shooting at about 8:24 a.m. Numerous graphic videos from the moments after the shooting were posted to social media.
"The train at that time began to fill with smoke. He then opened fire, striking multiple people on the subway and on the platform," said NYPD Commissioner Keechant Sewell.
Police said that he fired off at least 33 rounds from a Glock 17 9mm handgun before a magazine jammed in the gun.
Sewell said that none of the injuries appeared to be life-threatening. Five of the victims are listed in critical, but stable, condition.
CNN reported that the suspect was identified from a credit card that was left at the crime scene and was used to rent the U-Haul cargo van.
Police were also able to recover a bag at the crime scene with several alarming items inside including smoke bombs, a hatchet, hobby fuse, gasoline, and a key to the U-Haul van.
"We are asking for anyone's help with information: cellphone video, witness information, or if they can identify the perpetrator, or the renter of this vehicle, to call Crime-Stoppers at 1-800-577-TIPS," said New York's Chief of Detectives, James W. Essig, to reporters.
Witnesses said that they saw the shooter mumbling to himself before putting on his gas mask and starting his attack.
There is a $50,000 reward for information leading to the apprehension of James.
