With few leads and little evidence, frustration is mounting in the search for Brianna Denison four days after the 19-year-old college student mysteriously vanished from Reno.

Police questioned a man who gave a ride home to Denison’s friend the night Denison disappeared from the home near the UNR campus.

But investigators said today he is not a suspect in the apparent abduction.

UNR Police Chief Adam Garcia says at this point, they don’t have any credible leads. He told a Reno radio station tonight, that, in his words:

“Basically, Brianna has disappeared. She has fallen off the face of the Earth.”

Denison was last seen at 4 a.m. Sunday. Police said she was sleeping on a couch near an unlocked glass door after a night of partying. When her friends awoke later that morning, she was gone — but her clothes, purse and cell phone were left behind.

Police with search dogs have canvassed the neighborhood a half-mile north of the downtown casino district since Monday but have found no sign of the young woman, no footprints, no tire tracks that would aid in the investigation.

Reno police commander Ron Holladay says abductions by strangers are extremely rare anywhere, and even rarer in Reno. He says it’s very frustrating to have absolutely no clues, no evidence, no witnesses.
