A University of Arizona student who fell to his death last month climbing a rooftop tower was drunk at the time of the accident, the autopsy report states.

Toxicology results show Michael Evan Anderson, 19, had a blood-alcohol level more than twice the legal limit (allowed for drivers) when he died April 4. There also was evidence that he had smoked marijuana, but tests did not determine when he used the drug.

“Clearly he was intoxicated and that one (alcohol) is going to have the largest effect on his behavior, more so than marijuana would,” said Dr. Gregory Hess, chief medical examiner for Pima County. “The bottom line for us is this is a young man under the influence, primarily of alcohol, and was climbing that structure for whatever reason and fell.”

At about 4 a.m. April 4, Anderson, a freshman from Mission Viejo, California, was with another student when they gained access to the roof of the three-story Colonia de la Paz residence hall.

Anderson had climbed about halfway up a 20-foot tall ventilation tower when he fell onto the rooftop.

The death was ruled an accident.
