Three people are accused of participating in a prostitution ring based in Maryland Heights and Crestwood.

Police said the three participated in prostitution both at Witter's home and at a building at 8970 Watson Road in Crestwood.

Maryland Heights Police said an investigation into prostitution rings marketed online, Witter's phone number appeared in several ads.

Witter was charged with second-degree promoting prostitution; Hughes and Garner were charged with third-degree promoting prostitution.

A detective called the number and made an appointment for March 22, and he went to Witter's address in Maryland Heights.

Garner met the undercover officer wearing only her underwear, and told him to get undressed, police reported. When she started stroking his genitals, the officer gave a signal and a raid team entered the home, according to a court document.
