The former manager of Lawrence’s Club Magic pleaded guilty Monday to conspiring to operate a sex-trafficking business.

Sean Hall, 46, of Topeka, pleaded guilty to a single count of conspiracy, admitting he worked with others to operate a prostitution business out of Topeka, according to Tom Beall, U.S. Attorney for the District of Kansas.

Hall and six others were indicted in October 2015.

In 2012, Hall began working for Frank Boswell, who was a part-owner of Club Magic. The club, which is now closed, was located at 804 W. 24th St.

Alongside Boswell and others, Hall transported prostitutes between meetings with clients, the release said. He also posted advertisement pictures of prostitutes online and posted reviews of prostitutes online.

As many as 20 prostitutes were working for the organization at any given time, the release said.

The prostitution business spanned from Kansas to Missouri, Nebraska, Iowa, Arkansas, Tennessee and Texas.

Hall is scheduled to be sentenced on Oct. 3, the release said. Depending on his criminal history, Hall could face as long as five years in prison and a fine of up to $250,000.

Boswell, 42, of Topeka, still awaits trial.
