Prosecutors Monday were set to arraign the Bronx teen accused of opening fire and shooting two skaters late Saturday at the Bryant Park ice rink over the coat one man was wearing.
Corey Dunton, 16, was expected to be charged in Manhattan Criminal Court with attempted murder, and will be tried as an adult, authorities said.
The teen grinned and swore at reporters as he was taken from the midtown South Precinct station to his arraignment.
Dunton was captured less than a day after the shooting, when investigators found his Facebook page, with his admissions that he went to the ice rink and shot two people, NYPD Commissioner Ray Kelly said.
Kelly said the shooting stemmed from an earlier attempt by Dunton to steal the coat off one of the ice skaters.
"The two individuals did not know each other," he told reporters at Madison Square Park.
Dunton first asked for the coat, a Marmot Mammoth, but the 20-year-old victim refused and possibly argued with the shooter, Kelly said.
The oversize jacket, known as a "biggie," has been at the center of numerous crimes this year, he said.
The teen left, then returned a short time later and called out the victim before firing eight shots into the crowd, striking the 20-year-old man and a 14-year-old boy who was in the crossfire, police said.
Both victims suffered serious, but nonlife-threatening injuries.
The teen, who was shot in the back, was left partially paralyzed, police sources said.
Kelly said other skaters ran away in panic but some cooperated with investigators and helped identify Dunton, who was picked up at his mother's home in the Bronx on Sunday night.
He didn't make statements to police during his questioning, Kelly said. The weapon used in the case has not been found, but the investigation as to how the teen acquired the gun is ongoing.
