Timothy J. Stenovec Detectives at the scene of the stabbing Monday morning. Jairo Pastoressa, 25, a resident of the East Seventh Street tenement where the stabbing occurred, faces murder charges.

A 25-year-old East Village man was charged with murder last night in the fatal stabbing of another man early yesterday morning, the authorities said.

The suspect, Jairo Pastoressa, lived in a tenement at 272 East Seventh Street where the police said that Christopher Jusko, 21, was stabbed around 5:30 a.m. Monday. The authorities said that Mr. Pastoressa surrendered to the police shortly after the attack.

While detectives did not immediately provide details about a possible motive, Mr. Pastoressa’s neighbors said that the killing occurred after a dispute over a woman in whom both had a romantic interest.

The arrest of Mr. Pastroressa was confirmed by The Local this morning. It has also been reported by other news organizations.

One of Mr. Pastoressa’s neighbors, John Bonilla, said that a friend of Mr. Pastoressa’s family indicated that Mr. Pastoressa told investigators that he was acting in self-defense.

Mr. Bonilla described Mr. Pastoressa, his neighbor of about four years, as a “personable young man” and said that he “generally kept to himself.”

“We’d exchange hello and goodbye when he’d go out and walk his dog,” said Mr. Bonilla.

Mr. Bonilla said that neighbors along the stretch of East Seventh Street where the stabbing occurred were jolted by the crime.

“It’s very unnerving,” said Mr. Bonilla. “It doesn’t give you a good sense of security, and makes me wonder about staying in New York.”
