TUCSON, Ariz. -- University of Arizona police are trying to learn what a 19-year-old student was doing in the hours before he fell to his death while climbing a cooling tower atop a dorm.
Freshman Michael Evan Anderson of Mission Viejo, Calif., died Friday morning on the roof of the three-story dorm.
The Arizona Daily Star reported the investigation included analyzing security video at a fraternity house to determine where there was a party there and interviewing students and a cab driver.
Court documents indicated that detectives also searched Anderson's room in the dorm.
Police Sgt. Filbert Barrera said toxicology test results which could confirm whether Anderson was impaired by drugs or alcohol won't be available for several weeks.
