A recent graduate of Yale University in New Haven, Conn. stabbed another student before committing suicide early Tuesday morning, police said, according to Yale Daily News.

Tyler Carlisle attacked 21-year-old Alexander Michaud around 5:30 a.m. at a building across the street from the campus. Carlisle then jumped from the ninth floor of the Taft Apartments and landed on a terrace on the third floor, where he was found dead. As of 5 p.m. EDT, Michaud was reportedly in stable condition at Yale-New Haven hospital, according to the New Haven Register.

Carlisle graduated with a B.A. in philosophy last Monday, according to Yale Daily News. Michaud and Carlisle were close friends, students told Yale Daily News, and members of the Party of the Right, a constituent party of the Yale Political Union. Both were from Manchester, N.H.

"You could find Tyler Carlisle every Tuesday night at our debates standing up for what he believed in," Yale Political Union President Simon Brewer said in a statement, according to WTNH. "He was a principled, honorable man and widely respected across the Union."

What led up to the stabbing is unclear.

Yale issued the following statement after the incident, according to Inquistr and other sources:

"The New Haven Police Department has informed the University that Tyler Carlisle, who graduated from Yale College this year, died earlier today after falling from an apartment building window, and Alexander Michaud, a member of the Yale College Class of 2017, sustained stab wounds in the same apartment, and has been hospitalized.

"The University extends its deepest sympathy to the families and friends of these two members of the Yale community, and joins everyone in hoping for Alexander's full recovery.

"Yale's mental health counselors and staff of the Chaplain's Office are available to provide support to anyone from Yale on campus or in New Haven who is affected by this tragedy.

"The New Haven Police Department is investigating and Yale remains in contact with the department to provide any cooperation needed."
