A St. John's University lacrosse team co-captain from Suffolk County Long Island was arrested on Tuesday, October 22nd and is facing assault charges after he allegedly stabbed ex-teammate/roommate, nearly disemboweling him, during a fracas over loud music.

Matthew Stockfeder, 21, of Melville, who played lacrosse at Walt Whitman High School and is the current co-captain for the SJU lacrosse team, was arrested on Tuesday, October 22, after stabbing his roommate, Justin Corpolongo, 23, of Somers NY, the NYPD said.

The argument began late on Monday, October 21st, when Corpolongo got home to their off-campus apartment in Queens, complaining that Stockfelder's music was too loud. After exchanging words around midnight, Stockfelder headed to the "unofficial frat house" at 73-20 172nd Street, a few blocks away from the campus.

While Stockfelder was at the "frat house," he repeatedly texted his roommate so many times that it provoked Corpologno to show up at the house to confront him, and then the two began having words but eventually escalated to a physical fight.

During the fight, when Corpologno was holding Stockfelder's head down, he then "felt a sharp pain to his abdomen," the complaint states. Stockfelder allegedly pulled out a knife and stabbed Corpologno. The Daily News reports that the victim [Corpologno] did not know he was stabbed, not until he saw that he was bleeding profusely and realized that his “intestines were coming out."

After the incident, Corpologno was immediately rushed to Booth Memorial Medical Center at New York-Presbyterian Queens. The doctors found a 5-inch puncture to his small intestine, and he was rushed to surgery, the Post reported. Corpolgno underwent surgery and is expected to survive.

Matthew Stockfeder reportedly turned himself in to police on Wednesday and has been charged with 2 counts of felony assault; one count of felony assault with intent to cause injury with a weapon and one count of felony assault with intent to cause serious physical injury.

The University is aware of an incident involving a student and an alum that occurred at an off-campus location, not owned by the University, and is fully cooperating with the investigation by law enforcement officials,” St. John’s University spokesman Brian Browne said to Daily News.
