Walter Conwell, 41, has been sentenced to seven years in federal prison for sex trafficking crimes involving two victims, according to the United States Attorney’s Office for the District of Colorado. The sentence also includes eight years of supervised release after his prison term.

Prosecutors said Conwell recruited two individuals to work as prostitutes and transported them across state lines. He advertised the victims online and made promises such as providing housing, cars, health insurance, and clothing—none of which were delivered. One victim was coerced through harassment and by withholding her money and property. The other victim was under 18 at the time of the offense. Authorities stated that Conwell traveled to Texas, picked up the minor, drove her to Colorado, engaged in sex acts with her, and then promoted her for prostitution.

“Federal prison is the appropriate place for a man who somehow convinced himself it was okay to take everything from these young women and sell them for sex,” said United States Attorney Peter McNeilly. “This case demonstrates our unwavering commitment to pursuing justice for survivors of human trafficking.”

“Like all sex traffickers, this man preyed on people who were vulnerable.  The lack of respect he showed for basic human values is appalling,” said FBI Denver Special Agent in Charge Mark Michalek.  “His survivors face a difficult recovery process, but they are now on that path and their abuser is in prison, where he belongs. Combatting human trafficking continues to be an FBI priority as we work to keep communities safe.”

Senior United States District Judge Christine M. Arguello handed down the sentence on August 21, 2025. The Federal Bureau of Investigation conducted the investigation, while Assistant United States Attorneys Melissa Hindman and Alecia L. Riewerts prosecuted the case.

Case Number: 1:21-cr-00364-CMA
