ALFRED (AP) — The Maine woman convicted of running a prostitution business out of a Zumba fitness studio is headed back to court, this time to fight having to testify at the trial of one of her alleged clients.

Alexis Wright, sentenced in May to 10 months in jail, has been subpoenaed by prosecutors to testify at the trial of Donald Hill. Hill, a former high school hockey coach, is charged with engaging Wright for prostitution in 2011. He has pleaded not guilty.

He is the first of 68 people charged with paying Wright for sex to go to trial. At least 58 others have pleaded guilty or no contest.

Thursday’s hearing comes four days before the 53-year-old Hill is scheduled to go on trial.
