FORT COLLINS, COLO. ? Police suspect drinking contributed to the death of a Colorado State University student whose body was discovered over the weekend in a fraternity house.

It’s not clear what Samantha Spady, 19, a sophomore business major from Beatrice, Neb., was doing in the Sigma Pi fraternity. Her body was discovered Sunday evening in a lounge by a fraternity member giving a tour of the house to his mother.

Police estimated that she died Sunday morning so she may have been there about 12 hours before they were called.

An autopsy revealed that alcohol may have been a factor in the death. There was no sign of trauma and Spady was not sexually assaulted. Toxicology tests were also planned.

Citing an unnamed police source, the Rocky Mountain News reported Tuesday that Spady had a blood-alcohol concentration more than five times the legal limit for driving in Colorado.

Police were also reportedly investigating whether Spady and a friend were involved in a one-car accident over the weekend and whether she was drunk and called a fraternity member for a ride.

It’s not clear whether Spady drank at the fraternity house on Saturday night but police believe members of the fraternity checked on her and thought she had passed out.

Fraternity President Darren Pettapiece said there was no party at the house that night and no one he had spoken with had admitted drinking with Spady.

Adam Tatro, 23, and Chase Bruhn, 22, students at the University of Northern Colorado who had attended high school with Spady, said they don’t understand why no one took her to the hospital.

“This just doesn’t seem like her at all,” said Tatro, who drove with Bruhn from Greeley to Fort Collins after learning of Spady’s death. “Sam, she was a smart girl. If you knew her at all through high school, she wasn’t getting in trouble. She wasn’t out doing stupid things. She was an all-around nice girl. This was out of character.”

Spady was head varsity cheerleader, homecoming queen, a National Honor Society member and president of her class in Beatrice, a town of about 13,000 about 40 miles south of Lincoln. Her father, Rick Spady, owns several businesses, including Spady-Runcie, a car dealership in Beatrice.

“She was a pretty upstanding girl,” said Laura Tiedt, who graduated from Beatrice High School with Spady. “Sam was real popular and hung out with the popular kids, but she was always nice to everybody.”
