Jurors returned the verdicts Wednesday against Mark Strong Sr., who was accused of helping a fitness instructor use her studio as a front for prostitution.
Prosecutors say he was a business partner who controlled, supervised and managed the prostitution business.
The 57-year-old Strong is a married businessman. He has acknowledged having an affair with Alexis Wright and helping her open the studio but contends he didn't profit from her activities. His attorneys say he was a smitten lover who wanted to help the single mother.
Wright is awaiting trial and has pleaded not guilty.
