The daughter of a top Lawrence Police supervisor on Tuesday admitted helping launder money her boyfriend made dealing crack cocaine.

Erin Harmon, 25, pleaded guilty to one count of misprision of money laundering, admitting she helped Lawrence resident Darren D. Wilburn by letting him use her checking account and by hiding $11,000 cash in a desk drawer at her office.

Misprision of money laundering means she had knowledge of the crime but failed to report it.

She will be sentenced May 15 and faces a maximum sentence of three years in prison.

Her plea came during an afternoon hearing in U.S. District Court in Kansas City, Kan.

The case, investigated by the joint city-county Drug Enforcement Unit, caused friction within LPD. Harmon’s father, Kevin Harmon, is one of six LPD captains who are second in command only to Chief Ron Olin.

Kevin Harmon testified as a defense witness at a suppression hearing, where he questioned whether detectives’ warrantless search of his daughter’s workplace at the Kansas Department of Social and Rehabilitation Services was legally proper. But a judge ultimately sided with detectives and found that evidence from the search could be used in court.

Wilburn, 30, has pleaded guilty to money laundering and conspiracy to distribute crack cocaine and will be sentenced March 20. Three other co-defendants, Evann A. Hardy, 22, Lamar Johnson, 30, and Robert “Cowboy” Johnson, 52, also have entered pleas.
