The Las Vegas Review-Journal reports that Emily McCaughan died early Monday after falling from the 27th floor at the Circus Circus hotel to a roof on the third floor.
Family spokeswoman Mignonne Walstad says McCaughan panicked after taking the drug and went back to the hotel without her friends.
The Review-Journal says a Clark County medical examiner confirmed McCaughan’s death on Friday but hadn’t announced an official cause of death. Police on Saturday were still investigating the circumstances of her fall.
McCaughan was a student at the University of Arizona. Her family held a memorial service for her in Scottsdale on Saturday.
