MADISON, Wis. -

Prosecutors have charged the owners of a downtown Madison massage parlor with running a brothel.

Rising Sun massage parlor owners Charles Prindiville and his ex-wife, Catherine Prindiville, were charged Monday with conspiring to keep a place of prostitution, the Wisconsin State Journal reported. The Rising Sun's accountant, Donald Goodweiler, also was charged.

The complaint said Rising Sun workers told police that refusing to have sex with clients would get them fired.

Police have been investigating the Rising Sun since October 2010. Charles Prindiville's attorney, Charles Giesen, said he'll ask that the charges be dismissed due to prosecutorial delay, noting the earliest crime alleged in the complaint occurred in 2003.

Goodweiler told the State Journal he wasn't aware of the charges. No contact information could be found for Catherine Prindiville.

The Dane County Jail did not have booking photos for Catherine Prindiville or Donald Goodweiler Wednesday morning.
