Authorities say a Fort Atkinson massage business was at the center of a prostitution sting that has now landed its owner in felony trouble. Investigators allege the spa was being run as a house of prostitution and that a search warrant turned up items tied to the suspected operation.

According to Daily Dodge, 50-year-old Guiyuan Liu was charged Monday in Jefferson County Circuit Court. The case stems from a law enforcement sting earlier in April that targeted the business, and Liu is scheduled for a preliminary hearing on May 21.

Where investigators say it happened

Court filings identify the business as Lilian Spa, a storefront massage parlor in Fort Atkinson. A listing on Find The Seven places Lilian Spa at 1550 Madison Ave., Suite 102 in Fort Atkinson and shows a local phone number and posted operating hours.

What investigators say

Police reported running an undercover operation at the spa earlier in April in which, according to the case file, an informant was allegedly offered sexual services for an additional fee. After that sting, officers executed a search warrant at the business and say they seized evidence connected to the suspected prostitution activity. Those details are laid out in the charging notice filed in the case.

Legal implications

Wisconsin law treats prostitution and related conduct as criminal offenses and includes a specific crime for keeping or allowing a place of prostitution to operate. The Wisconsin State Law Library notes that Wis. Stat. §944.34, which addresses “keeping a place of prostitution,” is typically charged as a Class H felony, while prostitution offenses more broadly fall under Wis. Stat. §944.30 and carry their own penalties. Wisconsin State Law Library

What’s next

The case is still in its early stages. Liu’s preliminary hearing is set for May 21 in Jefferson County Circuit Court, where a judge will decide whether there is enough evidence for the case to move forward. Future court filings will outline any additional charges or formal statements from prosecutors. As of publication, there was no separate press release on county public pages announcing the investigation, and official records and hearing calendars are being maintained by the Jefferson County Clerk of Courts.
