Two Roxbury men convicted of human trafficking were sentenced to lengthy prison terms Monday, authorities said. Tyshaun McGhee, 33, and Sidney McGee, 29, were convicted Feb. 3 in Suffolk Superior Court on three counts of trafficking a person for sexual servitude, said Suffolk District Attorney Daniel F. Conley’s office. McGhee was convicted on two additional counts of deriving support from prostitution. McGhee was sentenced to 10 to 15 years in prison, and McGee to 10 to 12 years, prosecutors said. In September 2012, the defendants coerced three drug-addicted women into prostitution, marketing them online through photos and charging customers for sexual acts, said Conley’s office.Jennifer Smith can be reached at firstname.lastname@example.org.
