Prosecutors and the defense have concluded their first round of settlement discussions in the case of a Zumba fitness instructor facing charges of prostitution and tax and welfare violations. Wednesday’s closed-door settlement conference focusing on Alexis Wright lasted nearly five hours at the Cumberland County Courthouse. Assistant District Attorney Patrick Gordon of York County said that the meeting ended without a plea agreement, but that the parties hope to resume talks at a later date. Wright, 30, is accused of conspiring with insurance agent Mark Strong Sr. to run a prostitution business in Kennebunk in which she kept detailed records and secretly recorded the sexual acts.
