Princeton student found dead in lake was diagnosed with bipolar disorder

The Princeton University junior found dead last week in a lake near the Ivy League campus suffered from bipolar disorder, according to his obituary.

Lauren Blackburn’s cause of death hasn’t been determined yet, a spokesperson for the medical examiner’s office told The Post.

His obituary said that he died “after a courageous battle with bipolar disorder.”

Blackburn, 23, was found in Lake Carnegie on April 25, five days after he was reported missing. He was last seen near the college’s Firestone Library at around 6 p.m. on April 19.

Officials pinged his phone in the area of the man-made reservoir on April 22, prompting a search in the water.

Lake Carnegie sits just south of campus — near the university’s athletic complex — but about a mile from the library where Blackburn was last seen.

A National Merit scholar and Gates Scholarship recipient, Blackburn was majoring in English and was set to graduate in 2026.

The Corydon, Indiana native was described in his obituary as a “compassionate, thoughtful, and playful” learner who loved “Wuthering Heights” as well as the works of Virginia Woolf.

Between 2020 and 2021, he served the California Santa Rosa mission of the Church of Jesus Christ of Latter-day Saints.

“He enjoyed K-pop and cheering for the Celtics, Chiefs, and [Tottenham] Hotspurs,” read his obituary.

Blackburn spent last summer in South Korea, learning more about his Korean roots.

A memorial service for Blackburn has been set for May 4 at 5 p.m. inside the Church of Jesus Christ of Latter-day Saints in Corydon.

Blackburn’s parents have asked that any gifts in their son’s name be made to the International Bipolar Foundation.
