Sung Koo Kim, 30, was arrested following a court appearance in Yamhill County and is being held at the Multnomah County jail on $10 million bail.

In a court affidavit, detectives outlined their case against Kim and described what they found when they searched his Tigard home.

Among the items found on his computer were 40,000 violent pictures of tortured, raped and mutilated women and 4,000 pornographic and violent videos.

Detectives also discovered videos of two women doing laundry at Concordia University.

The arrest comes just four days after Kim pleaded innocent to charges of stealing women's underwear on May 2 from a dorm room at Oregon State University in Corvallis.

In addition to suspected of being a panty thief, Kim is also a person of interest in the disappearance of 19-year-old Brooke Wilberger, who has been missing for several weeks.

However, despite the unusual items Kim had stored on his computer, he still remains only a person of interest in the missing woman's case.

Kim's arrest comes just four days after he pleaded innocent to charges of stealing women's underwear on May 2 from a dorm room at Oregon State University in Corvallis.

Kim is scheduled to be arraigned on Tuesday.
