There may be a plea deal in the works for the business partner of a Zumba dance instructor charged with running a prostitution business from her Kennebunk studio. A lawyer for Mark Strong Sr. confirmed Wednesday that a conference with prosecutors is scheduled for Friday, where a settlement may be discussed. The 57-year-old Strong is scheduled to go on trial Tuesday in York County Superior Court on 59 misdemeanor charges of conspiring with Zumba instructor Alexis Wright to run a prostitution business. Strong’s attorney, Daniel Lilley, tells The Portland Press Herald, his client wants a deal in which he gets a small fine but avoids jail. Lilley says he’s removing himself from the case because Strong can no longer afford to pay him. Strong and Wright have pleaded not guilty.
