A 13-year-old has been arrested and charged in the stabbing death of Barnard College freshman Tessa Majors in a New York City park, according to multiple senior law enforcement officials.

The teen faces charges of second-degree murder, robbery and a weapons-related charge, the officials said. His specific role in the death was not immediately clear.

The juvenile was apprehended at about 11 p.m. Thursday, and as of Friday was not being charged as an adult.

Investigators are seeking two other people whom they believe had a role in the attack.

"I am absolutely confident that any individuals involved in this terrible, heinous attack will be brought to justice and will be brought to justice quickly," New York City Mayor Bill de Blasio said Friday during a radio interview.

Majors, 18, was stabbed repeatedly in Morningside Park, not far from Barnard's campus, before 7 p.m. Wednesday, according to the New York Police
"During the struggle, one of the individuals pulled out a knife and stabbed her several times," NYPD Chief of Detectives Rodney Harrison said Thursday. "She staggered her way up the street. One of the security guards saw her and called 911."

She was pronounced dead at a nearby hospital.

Police were questioning two teens, with their guardians present, Thursday, but they were later released, according to the NYPD.

Investigators believed there were between one and three suspects, one of whom stabbed Majors, in what Barnard officials said was an attempted robbery.

A law enforcement source told NBC New York that a witness saw a group of people running from where Majors was found by a security guard. A text alert sent to Barnard students said one male suspect was wearing a green jacket and a hat.

A $2,500 reward is offered for anyone who provides helpful information in the case.
