Lawyers for a Maine man accused of helping a Zumba instructor run a prostitution business are getting one more shot at convincing a judge to dismiss most of the remaining counts. The defense on Tuesday will argue in favor of a motion to toss 12 promotion-of-prostitution counts against Mark Strong based on “broadness and vagueness” of the original indictment. Strong also faces a 13th count, which is conspiracy to promote prostitution. The 57-year-old Strong from Thomaston stands accused of helping Zumba instructor Alexis Wright use her Kennebunk fitness studio as a front for prostitution. The insurance agent has acknowledged having an affair with Wright and helping her launch the studio but contends he never profited from her activities.
