Ann Arbor, Michigan — The University of Michigan community is mourning the unexpected death of Lucas Mattson, a 19-year-old engineering student who was found dead after a lengthy search in extreme winter conditions. His body was discovered on Saturday afternoon following his disappearance from a fraternity party the previous night.
Mattson, who hailed from Juneau, Alaska, was last seen around 1 a.m. on Friday, January 23, 2026. He had reportedly left the Delta Chi fraternity party and was walking alone on Hill Street. At the time, he was wearing only a light T-shirt, jeans, and sneakers, leaving him vulnerable to the zero-degree temperatures that gripped the area.
Authorities received a missing persons report about 15 hours later, which prompted multiple agencies, including the Ann Arbor Police Department and the University of Michigan’s Public Safety and Security team, to mobilize a search effort. The hazardous weather made the search particularly perilous, with temperatures plunging far below freezing.
The search culminated tragically at approximately 12:05 p.m. on Saturday, when Mattson’s body was located on Cambridge Road, just a couple of blocks from where he had been last seen. Preliminary assessments by the Ann Arbor Police indicated no signs of trauma, and an autopsy will be conducted to determine the exact cause of death.
In a statement, Police Chief Andre Anderson extended condolences to Mattson’s family and the university community. Officials noted that investigations are ongoing, and they urge the public to refrain from speculation as they work to understand the circumstances surrounding Mattson’s death.
University Interim President Domenico Grasso expressed profound sorrow while highlighting the importance of careful reflection during this trying time. He acknowledged that while fatalities among students are not uncommon at large universities, the circumstances of Mattson’s passing have prompted significant concern and conversation within the community.
In light of this tragedy, the University of Michigan has initiated a review to assess safety protocols during social events and has made counseling services available to support students, faculty, and staff impacted by this loss.
Safety concerns raised by this incident have reignited discussions among students about the importance of vigilance, particularly in severe weather conditions. The university encourages the implementation of safety practices such as traveling in groups and utilizing campus resources designed to promote student security.
Additionally, a GoFundMe campaign has been set up to assist with expenses for Mattson’s family during this difficult time, garnering substantial support from the university community and beyond.
As the University of Michigan grapples with this heartbreaking loss, the incident has shed light on the hazards posed by winter weather, even to those familiar with cold climates. Students and faculty alike are reflecting on the responsibilities of both individuals and event organizers to prioritize safety in challenging conditions.
In the aftermath of Mattson’s untimely passing, the community is coming together to honor his memory and to foster a renewed commitment to safety and care among peers.
