Two men face federal sex trafficking charges after being arrested during an undercover operation at an Independence hotel.

Calvin Anthony Miller, also known as “Serious,” 34, and his cousin, Henry Dailey, 36, were charged with conspiracy to commit sex trafficking against three victims Tuesday in U.S. District Court in Kansas City.

The arrest was part of Operation Cross Country X, an international FBI investigation of sex trafficking in partnership with local law enforcement agencies, including the Independence Police Department.

According to court documents, a federal undercover agent assisting the Independence Police Department, posed as a customer attempting to hire a prostitute. On Friday, the agent located a listing online for a woman and arranged a meeting with her at a hotel.

At the meeting, the woman victim provided information on Miller, saying he was her pimp, and on Dailey. She told the law enforcement officials that both had been exploiting commercial sex workers and that Miller had been violent and abusive.

According to the court documents, the first victim showed police two more victims in online advertisements. One was described as “a very young baby-faced girl” who had recently arrived in the Kansas City area on a bus with Dailey.

An Independence police detective located the young victim with Dailey at an Independence hotel. They were detained, and the victim told the detective that she wanted away from the group and wanted to go home.

Law enforcement officers also found a third victim at the hotel. According to the court documents, she told police, “If I tell you anything he will kill me,” and started crying. That victim said she did not believe that police could provide enough security to protect her from the men and that she also wanted to leave and get away from Miller.

While at the hotel, agents determined that Miller had rented two rooms on the third floor and a room on the first floor. They found him on the third floor and when he refused to comply, he was taken to the ground and handcuffed by officers.

Each of the three victims told law enforcement officers that Miller and Dailey required them to work as prostitutes, threatening them with violence and death if they tried to leave, and took all of their money. Court documents also said the victims told police that Miller and Dailey forced them to use drugs to keep them addicted and dependent on them.

The third victim showed federal agents a ledger of the approximately $13,000 she allegedly paid Miller for various acts over the last month. She told police that Miller had brought her from St. Louis to work in Kansas City, Las Vegas and as far away as Washington state to perform as a commercial sex worker, despite a broken hip.

That victim told agents she wanted to leave but that Miller had a Google voice account that allowed him to view and hear all text messages and verbal conversations on her phone.

Miller and Dailey remain in federal custody pending a detention hearing on Oct. 20.
