He was identified as Andre Gordon.

“He’s in custody. No one else was injured,” Trenton, New Jersey, police director, Steve Wilson, told CNN.

The 26-year-old suspect allegedly killed three people in two different homes before carjacking a driver and heading for New Jersey, media reports said.

Wilson said authorities who were looking to apprehend Gordon initially thought he was barricaded inside a home which prompted setting up of a perimeter of an area.

“Apparently, before the perimeter was completed, the suspect was able to get out of the location unseen. However, our information was that he was still in there,” Wilson told CNN.

“The suspect was actually walking on New York Avenue,” Wilson said. “He was stopped and identified and taken into custody.”

The FBI office in Philadelphia told CNN they are “aware and tracking the incident” and are “working closely with our local partners.”

According to reports, the Bucks County St. Patrick's Day Parade was cancelled following the shootings in Falls Township.
