Search on for Woman Who Disappeared From Nevada Home

A 19-year-old college student mysteriously vanished from a Reno, Nev., home early Sunday morning, and cops fear she may have been kidnapped.

Brianna Denison, a student at Santa Barbara City College who is from Reno, was staying with friends near the University of Nevada, Reno. She was last seen at about 4 a.m. Sunday, when she returned home from a party and went to sleep on the couch wearing sweat pants and a T-shirt.

"We're treating this as an abduction case right now," Lt. Robert McDonald of the Reno Police Department told FOX News. "A small amount of blood on her pillow is of interest to us."

Cops are looking for a tan-colored, later-model GMC or Chevy Suburban and a white male, about 45 years old, who might be of Latin descent.

"He's certainly a person of interest. We're treating him as a person of interest, not a suspect," McDonald said.

The man driving the vehicle had picked up a friend of Denison's earlier that evening from the party both were attending when the friend was trying to hail a cab and dropped her off without incident at Mackay Court, the residence where she lived and Denison was staying, McDonald told

"We don't know who he is," McDonald said. "We know he was outside the residence, but he could have come back. ... Maybe he saw something or knows something that might be of interest."

Denison, who is from Reno, is described as white, 5-feet tall, 98 pounds, with long dark brown hair and blue eyes.

Investigators say she may have been wearing light blue or pink sweat pants, a T-shirt and no socks or shoes when she disappeared. Her purse and cell phone were found in the house, but a brown stuffed bear that belonged to Denison is also missing, police said.
