A Portland-area man accused of stealing thousands of pairs of women's underwear from college dorms in three Oregon counties had nothing to do with the disappearance of a 19-year-old college student in May, his father insisted Tuesday.

Sung Koo Kim (search), 30, has "a strong alibi ... He is innocent, but it's not time to speak out," his father, Joo Kim, told The Associated Press in a telephone interview.

In a search of the suburban home Kim shares with his parents, police found more than 3,000 pairs of women's underwear marked with the date and the dorms they were taken from, according to an affidavit filed in Multnomah County court.

Police also found dryer lint labeled as being from the Corvallis apartment complex where 19-year-old Brooke Wilberger (search) was last seen, according to the affidavit by Portland police detective Bryan Steed.

In addition, a search of Kim's computer by police yielded 40,000 pictures of women being tortured and raped, according to the affidavit.

Police also found videos of two women doing laundry at Concordia University (search) in Portland — taped without their knowledge, the affidavit states.

Steed called Kim a suspect in the Wilberger case. But the affidavit says there is "not probable cause" to charge Kim in the disappearance of Wilberger, a Brigham Young University (search) student who was visiting her sister in Corvallis when she vanished May 24.

Corvallis police have said Kim is one of four persons "of significant interest" in their investigation of Wilberger's disappearance.

Kim's attorney, Janet Lee Hoffman, said there is evidence that places Kim away from Corvallis on the day that Wilberger vanished.

"We've provided substantial evidence that he was not involved with the disappearance in Corvallis," she said.

Kim has been arrested in three counties on charges of stealing women's underwear from college dorms. After the first two arrests, his parents posted bail.

After Kim was arrested in Multnomah County on Monday, bail was posted at an unusually high $10 million.

Kim was arraigned in Multnomah County court on new burglary and theft charges Tuesday afternoon. Hoffman, his lawyer, asked for extra time to negotiate his release from jail.

Lt. Ron Noble, a spokesman for the Corvallis Police Department, said Wilberger's family expressed concern at the contents of the police affidavit.

"Overall, it is disturbing information," Noble said. "It's not pleasing for anybody to hear the types of photos and documents that Mr. Kim (allegedly) had on his computer."
