Brianna Denison was last seen around 4 a.m. Sunday when she went to sleep on her friend’s couch after a night of partying. She slept near an unlocked glass door and used a 2-foot-tall teddy bear as an extra pillow, police said.
When the friend awoke, Denison and the teddy bear were gone. Her purse, cell phone and clothes, including two pairs of shoes, were undisturbed, police said.
“We have not come up with any other clues, any of the items or anything that would lead us to Brianna at this time,” police Lt. Ron Holladay.
Detectives were awaiting test results on whether a stain on the pillow she was using was blood.
The FBI and two investigators from the National Center for Missing and Exploited Children joined the search Tuesday. Police aided by helicopters and dogs scoured the neighborhoods near the home.
The search teams planned to concentrate on a park near the home before a snowstorm later Tuesday, police spokesman Steve Frady said.
Family members Monday night pleaded for help and her safe return. They described Denison as caring and responsible.
“It gives us a little bit of fear because that is the type of person Brianna is; she would be contacting us if she could,” her aunt, Lauren Denison, told reporters Monday night.
Denison is a psychology student at Santa Barbara City College in Santa Barbara, Calif., and was back in her hometown of Reno for winter break.
In the hours before her disappearance, Denison had been party-hopping at venues associated with a weekend snowboarding event, including attending a rap concert at the Sands Hotel and Casino.
Investigators want to talk to a man who dropped off a friend of Denison’s at the home that night, police Lt. Robert McDonald said.
The friend had approached the man at the casino for a ride after the concert, but the man did not go inside the home, he said. The man is not a suspect but is being sought for questioning.
Denison’s friend, K.T. Hunter, told the Reno Gazette-Journal that the couch is against the wall of the bedroom where she was sleeping with her dog. She said that she never heard a noise and that the dog never barked.
Hunter said Denison was sober the night she vanished and had planned to pack Monday to go back to Santa Barbara.
Reno police Tuesday also said there doesn’t appear to be a connection between Denison’s disappearance and separate attacks late last year on two female students near the University of Nevada, Reno.
