There was a struggle, and one of the attackers pulled out a knife and stabbed Ms. Majors several times, he said.

The attackers fled and Ms. Majors staggered up a flight of stairs, out of the park and onto the street, where a school security guard found her and called 911.

Earlier this year, several people reported that they had been approached from behind in the park and punched by young people.

As of Dec. 8, there had been 20 robberies inside Morningside Park or on its perimeter this year, compared to seven in the same period last year.

Since June, five people reported being robbed on or near the staircase at 116th Street and Morningside Drive, near the spot where Ms. Majors was killed.
