A 19-year-old University of Michigan student who went missing amid dangerously cold weather conditions has been found dead following an extensive overnight search, authorities said.
Lucas Mattson, an engineering sophomore at the university, was discovered unresponsive at around 12:05 p.m. on Saturday in the 1900 block of Cambridge Road, nearly 20 hours after he was last seen, according to the Ann Arbor Police Department (AAPD).
