Two men face up to life in prison when they are sentenced in April for trafficking teenage prostitutes across the D.C. area.

Ivan Williams, 28, and Dennis Davis, 26, were found guilty by a jury in Alexandria federal court Wednesday evening. Prosecutors said the men used the proceeds from prostitution to fund their dreams of rap stardom.

Several former prostitutes testified against the two men, including two women who pleaded guilty to helping traffic minors. One, Davis's ex-girlfriend, had worked for him as a prostitute when she was underage. When he went to prison for that crime, she had his name tattooed on her hip. She testified against him in this case, she said, because he had attacked her younger brother.

Defense attorneys emphasized that the evidence came largely from co-conspirators who were likely to receive reduced sentences for their testimony and had lied to law enforcement in the past.
