Barnard College students expressed a measure of relief Sunday at the arrest of Tessa Majors’ alleged killer — but remained on edge over her senseless slaying during a botched robbery in nearby Morningside Park.

“I’m glad they caught him,” said sophomore Ellen Baker, 19.

“I’ve definitely felt less safe since the murder … I’m glad he’s off the street, for sure.”

Rashaun Weaver, 14, was ordered held without bail Saturday on charges including second-degree murder and first-degree robbery in the fatal stabbing of Majors, 18, on Dec. 11.

Sophomore Parker Cohen, 20, said she was upset it took cops more than two months to bust Weaver on Friday night in the lobby of his home in the Taft Houses in East Harlem, but added, “I’m glad they did.”

“The fact that he was basically a few blocks away when they [arrested] him is crazy to me,” she said.

“He’s been around this whole time.”

Freshman Katie Ludlum, 19, said Majors’ killing “shows that this kind of thing … can just happen to anyone.”

“You come to New York and everyone’s like ‘Oh, it’s so safe now,’ ” she said.

“I’m not afraid to walk down the street, but I would be lying if I said I wasn’t a bit more careful.”

Senior Marina Knowles, 21, said that “I feel better knowing he’s not out there, but I still get a little nervous every time I go into that park.”

“I’ve walked through that park a million times and I’ve never had a problem,” she said.

“Now it’s completely different even though, rationally, I know I’m probably not going to get attacked.”

At the Taft Houses, neighbors described Weaver as a bad kid, with one woman saying, “I knew he would hurt somebody.”

“You get a feeling, that look he gave, like, ‘I don’t give a f–k and I will hurt you,’ ” she said.

A male neighbor said the teen “would ride his bike in circles in the lobby.”

“A few months ago, he picked up his bike to go in the elevator and missed an old woman’s head by a inch, less maybe,” he said.

“I said, ‘Yo! Young man! Be more careful, you could kill someone, swinging that thing like that here … He just gave me a look. It was like, cold, you know. Like, ‘So what?'”

Meanwhile, an aunt, Sheila Weaver, identified Weaver’s father as Clifford Weaver, who’s in custody on a parole violation.

Clifford, 36, was initially imprisoned in January 2017 for drug possession in Brooklyn, then locked up again in September 2019 for violating his parole, records show.

He could be released next month.

No one would answer the door at Rashaun’s apartment, but his paternal grandfather, also named Clifford, said Rashaun phoned him before his arraignment, denied the charges against him and said he was OK.

The grandfather, a widower and retired doorman, also said Rashaun enjoyed playing basketball with his father before he went to prison.

Majors’ family “doesn’t have a statement at this time,” a spokeswoman said.
