Charles Oliver Craigslist Rapist: Man Suspected Of Raping As Many As 25 Women Gets $3 Million Bond

A Woodstock, Ill. man accused of raping potentially as many as 25 women he met through Craigslist was held on $3 million bond after a Tuesday hearing.

Charles Oliver, 54, has been charged in five attacks so far as police look for more potential victims, reports ABC Chicago. Prosecutors say Oliver solicited hundreds of escorts through the online classified service and videotaped many of the encounters.

According to WGN, prosecutors say Oliver carried out his crimes because he was "never popular with women" and called the area where some were allegedly tied up, taunted, photographed and brutalized his "playroom."

Oliver is accused of soliciting women for sex, filming many of the acts, only some of which were consensual. Prosecutors say he threatened to kill some of his victims if they went to the police, according to CBS Chicago.

Oliver allegedly kept some personal items from some of the victims to prevent them from contacting authorities, Fox Chicago reports. Investigators are now using cell phones, ID cards and photos of driver's licenses they found in Oliver's home to track down other possible victims.

"Now that I know where you live, you can't call the police, or I'll come after you," Oliver allegedly told one woman, according to Assistant State's Attorney Sharyl Eisenstein.

Jody Raphael, a DePaul University law professor who researches and writes about the sex industry, told the Tribune some men "falsely believe that if they're paying for sex, they are entitled to 'do whatever they want' to the woman."

"They view the woman as a commodity, not a person," Raphael said. "It's a license to be violent."

Next-door neighbor Julie Randecker, who knows one of the victims told ABC, "She thought she was going to a modeling shoot. He got her into the car, put a plastic bag over her head and then brought her [to his home.]"

Court records indicate Oliver met his alleged victims between November of 2011 and early this year.

Oliver faces charges of criminal sexual assault and unlawful restraint, and is set to appear in court next on April 12.
