Two men who ran a brothel in Columbia have been sentenced to federal prison.

The Columbia Missourian reports Barry Manthe was sentenced Monday to 18 months in prison and Ronald Clark was sentenced to 30 months. Both men pleaded guilty to using the internet to promote a prostitution business.

Another man, Kenneth Jones, was sentenced in December to 15 years in federal prison for the sex trafficking of a minor.

The FBI learned in June 2016 that Jones was forcing a 17-year-old runaway from Wisconsin into prostitution. She was found at a Columbia residence that Manthe and Clark operated as a brothel. The girl told investigators that Manthe placed ads in on the website Backpage, Clark collected a fee from the prostitutes and Jones got the rest of the money.
