former police officer, school board member sentenced to 10 years
in prison for attempted sex with a minor

May 14, 2012

KANSAS CITY, Mo. -- David M. Ketchmark, Acting United States Attorney for the Western District of Missouri, announced that a former Lansing, Kan., police officer and school board member was sentenced in federal court today for attempting to entice a minor for illicit sex.

William Brian Duncan, 41, of Leavenworth, Kan., was sentenced by U.S. District Judge Howard F. Sachs to 10 years in federal prison without parole. The court also ordered that, following his incarceration, Duncan will be on supervised release for the rest of his life.

On Oct. 24, 2011, Duncan pleaded “no contest” to using the Internet to attempt to entice a minor to engage in sexual activity, and to crossing the state line to attempt to engage in a sexual act with a minor. Duncan was an officer with the Lansing, Kan., Police Department until November 2010. He had been a DARE officer and coordinator of the Safe Kids program and was named Officer of the Year in 2008. Duncan resigned from the Lansing School Board in November 2010.

Duncan had numerous online conversations with a person he believed to be 14 years old. In reality, Duncan was communicating with an undercover law enforcement officer. Duncan corresponded with the undercover officer on multiple occasions in December 2010; many of the conversations were sexual in nature. Duncan made several statements indicative of his criminal intent and desire to engage in sexual activity with the minor.

Duncan began making arrangements to meet with the minor in person during an online chat on Tuesday, Dec. 28, 2010. Duncan drove from his residence in Kansas to the meeting location in Missouri the next day with the intent to engage in sex with the 14-year-old minor. When Duncan approached the location, he was pulled over by a Kansas City, Mo., police officer and arrested.

This case was prosecuted by Assistant U.S. Attorney Teresa Moore and Senior Litigation Counsel Gregg R. Coonrod. It was investigated by the FBI Cyber Crimes Task Force.
