A Zumba fitness instructor who pleaded guilty to using her Maine studio as a front for prostitution is due to be sentenced, bringing to an end a scandal featuring sex videos, exhibitionism and pornography. Under a plea agreement, Alexis Wright is due to be sentenced Friday to 10 months in jail for 20 counts including prostitution, conspiracy, tax evasion and theft by deception. The 30-year-old Wright was accused of conspiring with an insurance business owner to run a prostitution business in which she videotaped clients without their knowledge and kept detailed records over an 18-month period indicating she made $150,000 tax-free while collecting welfare. Under the agreement, prosecutors will seek restitution of $57,280. Prosecutors say Wright cooperated with them and spared the state an expensive trial.
