MOSCOW, Idaho (AP) — Officials at the University of Idaho say they're reviewing the school's substance abuse policies and its relationships with fraternities and sororities in the wake of a freshman's alcohol-related death.

Eighteen-year-old Joseph Wiederrick froze to death under a bridge last month after he apparently got drunk at a fraternity party and became disoriented while walking home.

Police said his blood-alcohol level was 0.17 at the time of his death, more than twice the legal limit to drive in Idaho. Several students at UI and neighboring Washington State University have suffered alcohol-influenced injuries in recent month, and one WSU student died from alcohol poisoning last year.

UI Dean of Students Bruce Pitman says the school has been focusing on education and intervention but they're looking for ways to do more.
