Sheriff Hires Ex-Prostitutes, Closes Mother-Daughter Brothel

The Cook County sheriff's office has added two former prostitutes to the payroll as part of its efforts to combat the world's oldest profession, STNG Wire reports.

Sheriff Tom Dart hopes to use the women to glean inside information that will help his department target pimps and human traffickers.

"We were trying to use our brains" to fight prostitution, Dart said.

Dart's office also announced Wednesday the arrests of a west suburban mother and daughter on prostitution charges following a three month investigation.

Kimberly "Big Kim" Miniea, 49, and her 19-year-old daughter, Kimberly Petersen, 19, were charged with felony pandering and keeping a house of prostitution after authorities executed a search warrant on their Berkeley home, STNG Wire reports.

A March lawsuit Dart filed against Craigslist accusing the site of creating "the largest source of prostitution in America" contributed to the site's removal of its "erotic services" section in May.
