NEW HAVEN, Conn. (PIX11) – A Yale student who recently graduated stabbed another student before jumping to his death early Tuesday morning, according to police.

The graduate, identified in a statement from the school as Tyler Carlisle, attacked 21-year-old Alexander Michaud around 5:30 a.m. at a building across the street from the campus, police said.

Carlisle then leaped from the ninth floor of the Taft Apartments, landing on a terrace three stories below, officials said.

Michaud is in stable condition at Yale-New Haven hospital.

Both men are from Manchester, New Hampshire, according to their Facebook pages, but police would only say that they were acquaintances.

It’s still not clear what happened before the stabbing.

Yale issued the following statement after the incident:

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.
