A Fruitless Search

Following Wilberger's disappearance, hundreds of volunteers helped search for her and held several prayer vigils for her safe return. The story generated national headlines, as the case was featured on "America's Most Wanted." The family of Elizabeth Smart, the Utah girl who was kidnapped in 2002 and safely recovered nearly a year later, contacted the Wilbergers to give them support and advice.

The National Center for Missing and Exploited Children sent retired investigators to help local authorities with the search and released four computer-generated photos showing how Wilberger might look with various hair lengths and styles. A "Find Brooke" Web site (www.findbrooke.com) was set up to help in the search, and the Wilbergers had pink bracelets made with the Web site address and the national hot-line tip number to increase awareness of the case.

Another man was initially the focus of the investigation. Police investigated a man accused of stealing women's underwear from three different Portland-area college dormitories or laundry rooms, including an April 2004 burglary at Oregon State University's Sacket Hall, which is near the site where Wilberger was last seen. But last February, Corvallis police said they had found no evidence that linked the alleged panty thief, Sung Koo Kim, to Wilberger's disappearance.

"It was nothing earth-shattering. We just finished following all the leads and tips we had on Kim. He's a pretty complex man," Lt. Ron Noble, a spokesman for the Corvallis police department, said at the time. "We wanted to be as thorough as we could. With as much notoriety as Kim has received, we would hate for people to think that we were at a dead end, that this is a cold case. That would be far from the truth."
