An Ames nurse practitioner and business owner, Carl Dale Markley, has been sentenced to life in federal prison on fifteen counts of sex trafficking by fraud and coercion. Markley, 45, was found guilty of using his professional position to exploit dozens of teenage boys, young men, and a few young women from at least 2001 to April 2023.
Markley's actions involved deceitful claims that sexual acts were necessary for research or other false pretenses. He recorded the abuse with hidden cameras. The investigation began in December 2022 when the Ames Police Department received a complaint about unauthorized physicals on minors. A joint effort by local and federal agencies led to hundreds of interviews and numerous search warrants.
Despite pleading guilty to the charges in November 2024, Markley continued to deny responsibility at sentencing. Chief District Judge Stephanie M. Rose described his justifications as "delusional."
"This case is a stark reminder that those who abuse positions of trust for personal gain will be held accountable," said Ames Police Department Police Chief Geoff Huff.
FBI Omaha Special Agent in Charge Eugene Kowel emphasized the commitment to justice for victims: "Carl Markley used trust and manipulation... The FBI and our local, state, and federal partners are committed to bringing sexual predators to justice."
DCI Assistant Director Don Schnitker remarked on the significance of this outcome: "Today marks a significant victory in Iowa’s ongoing fight against human trafficking."
United States Attorney Richard Westphal commented on the necessity of Markley's sentence: "Markley’s life sentence was absolutely warranted... Our gratitude to the courage of the victims..."
The case was investigated by multiple agencies including the Ames Police Department and prosecuted by Assistant United States Attorneys Kyle J. Essley and Amy L. Jennings.
Human trafficking involves exploitation through force or deceit without requiring transportation across state lines. Signs include excessive work hours or unexplained gifts. Suspicions should be reported via hotlines provided by law enforcement agencies.
