Reno police said that there was no initial indication that Denison had been drinking heavily or using drugs Saturday night, and that none of the roommates who live in the house reported any altercations at the casino party. The house was not locked during the night, so there is no evidence of a forced entry.
Reno police also urged caution regarding two reports about Denison's disappearance -- one about text messages that may have indicated a breakup between Denison and her boyfriend and the other about possible connections between Denison's disappearance and two unsolved assaults of young women near the university.
"There was some texting going on back and forth, but I don't have any more information than that," Frady said.
As for a link between Denison's disappearance and the pair of assaults, police said in a statement that "there does not appear to be a connection," and that the two assaults remain under investigation.
Denison is described as 5 feet tall, weighing 98 pounds, with long dark brown hair and blue eyes. Detectives say Denison may be wearing light-blue or pink sweat pants and a white tank top.
