The medical examiner said Wednesday that an autopsy reveals an OU senior was drunk when she fell to her death from the campus administration building.
Casey Cooke had been applying to medical school.
Witnesses said Cooke was drinking at a bar near campus before she ignored warning signs and climbed a campus building's fire escape.
She was on the phone with a friend when she slipped and fell three stories to her death.
Her blood alcohol level was two times the legal limit.
The fire escapes on that building have since been removed.
