NEW WINDSOR, N.Y. (CBSNewYork/AP)– Police have arrested a suspect following a fatal stabbing inside an upstate New York supermarket.

New Windsor Town Police Sgt. Stephen Sager says in a release that 35-year-old Andrew Goodenough was arrested inside a Shoprite supermarket on Saturday morning.

He is facing a second-degree murder charge. The name of an attorney to comment was not immediately available.

Police say they found a 35-year-old man stabbed and unconscious inside the store at about 9:40 a.m. The victim was taken to a hospital, where he was pronounced dead.

Police said Goodenough quietly walked behind the victim in the produce aisle and sliced his neck with a box-cutter, then walked away, CBS2’s Brian Conybeare reported. Officials said there was no altercation, no arguing, and no apparent connection between the two men.

Police quickly sealed the store with some 250 people inside and after 45 minutes they found the suspect trying to blend in like a regular shopper.

“We can confirm that an unfortunate incident took place this morning at our store. The store will remain closed for the rest of the day while police conduct a thorough investigation. While we can’t discuss the ongoing investigation, we are working with the police and reaching out to all of our associates. Our thoughts and prayers go out to all those involved,” Shoprite told customers in a statement.

Police did not immediately release the victim’s name, pending notification of kin.

Nobody answered the door at the suspect’s apartment, just a short walk from the crime scene. Neighbors described him as a troubled man.

“I stopped hanging out with him because he does flip, he does like a 180,” one neighbor told CBS2.

He said his unstable temper and strange threats of violence were too much.

“He’s definitely unstable,” the neighbor said.

New Windsor is about 65 miles north of New York City.
