Nineteen-year-old college student Brianna Denison is missing according to her family and authorities.  She was staying in Reno, Nevada when she went missing Sunday morning.  Police believe she was abducted via an unlocked sliding glass door she was sleeping next to.

Brianna Denison, a student at Santa Barbara City College, 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 sweatpants and a T-shirt.

A spot of what appeared to be blood was found on her pillow. Police have sent it to the lab for testing. The couch where Denison was sleeping was in front of an unlocked glass door. Investigators believe she may have been abducted.

Two University of Nevada students last year were grabbed and sexually assaulted from behind during the early morning hours.

If you have any knowledge of Brianna’s whereabouts then please report them to the police.
