MILWAUKEE, Wis. (WTAQ) - A Milwaukee man has been sentenced to 25 years in prison for running a child prostitution ring involving a half-dozen girls in 4 Midwest states.

40-year-old Todd “King Tut” Carter was the first in Wisconsin to be convicted under a federal law that cracks down on child sex trafficking. Authorities said Carter had his teenage son recruit the girls in Wisconsin, Illinois, Iowa, and Minnesota. He then posted their nude photos on Craigslist.

Carter pleaded guilty in February to sex trafficking and conspiracy. Federal Judge Charles Clevert said the plea spared the victims families from, “details that would perhaps make them shudder.”

The judge told Carter that he adversely affected the minds and ambitions of the teenage girls. Clevert also noted that Carter owes child support to over 16 kids born to different women – and he fathered a child with one of the victims in the prostitution case. Carter’s 20-year-old Nicholas earlier pleaded guilty. He’ll be sentenced later this month.
