Former Drug Task Force Detective Sergeant Convicted of Misconduct in Public Office


MADISON — Attorney General J.B. Van Hollen has announced that Timothy Madson, a former Jefferson County Detective Sergeant and former supervisor of the Jefferson County Drug Task Force, was found guilty Friday, July 25, 2014, of Misconduct in Public Office after a four-day jury trial in Jefferson County.


Madson served as the supervisor of the Jefferson County Drug Task Force from 2003 until late 2011.  During that time, Madson wrote more than $20,000 in checks to himself from the Task Force undercover buy fund, which was permissible; however, Madson converted funds to his own use and hid his actions by manipulating the expense reporting system by reporting hundreds of fabricated expenses and attributing most of those expenses to cases worked by task force investigators. Madson, by virtue of his position, had control over this account and was responsible for approving the disbursement of these funds, and the jury found his actions to be beyond his lawful authority.


Waukesha County Judge Lloyd Carter presided over the Jefferson County trial.  The case will be set for sentencing at a future date.


Assistant Attorney General David W. Maas is representing the State.  This investigation was conducted by the Wisconsin Department of Justice Division of Criminal Investigation (DCI) at the request of the Jefferson County Sheriff’s Department.
