A newly minted Yale University alumnus allegedly stabbed a younger classmate before killing himself Tuesday morning at an off-campus apartment complex in New Haven, Connecticut. Tyler Carlisle, who graduated from Yale last week, attacked 21-year-old Alexander Michaud, Yale class of 2017, early Tuesday, the New York Daily News reported. Carlisle died on scene, while Michaud was in stable condition.

The New Haven Police Department was called to Taft Apartments near campus at about 5:30 a.m. Tuesday, the Yale Daily News reported. Carlisle stabbed Michaud, then jumped from the building's ninth floor. He landed on a third-floor terrace and died. Michaud was taken to Yale-New Haven Hospital to be treated for his injuries.

Carlisle and Michaud were acquaintances, and both participated in Yale's Party of the Right, a conservative group in the school's political union, the New Haven Register reported. It was unclear what caused the early-morning confrontation, which the New Haven Police Department was investigating Tuesday afternoon.

Carlisle had graduated with a degree in philosophy May 18 after entering Yale in 2011. He worked on Rick Santorum's 2012 campaign for president, as well as Joseph Bentivegna's bid for Congress, according to his LinkedIn page. Carlisle wrote that he planned to explore "a number of options in the private and public sector" after graduation.

Michaud's LinkedIn profile lists him as an order administrator for the Life is Good company. He enrolled at Yale in 2012, where he's also publisher of the right-wing Yale Free Press, the Associated Press reported.

Yale administrators released a statement Tuesday offering mental health services to students. The university's summer term starts June 1, according to its website. "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," the statement said.
