A 13-year-old boy has been arrested after confessing in the stabbing murder of Barnard College freshman Tessa Majors in Morningside Park, a high-ranking source confirmed to The Post on Friday.
The teen had a knife on him when he was picked up Thursday night in the lobby of a building close to the park, the source said. He was taken to the precinct on trespassing and weapons charges — and then confessed to the murder, telling investigators that he and two friends tried to rob Majors, 18, before stabbing her, the source added.
The suspect’s exact role in the early evening attack is unclear, another source said.
Police said Majors was stabbed several times at the base of stairs in Morningside Park near West 116th Street and Morningside Drive around 5:30 p.m. Wednesday. She managed to climb up the stairs but collapsed in the view of a school security guard.
Majors was rushed to Mount Sinai St. Luke’s Hospital, where she died.
