The trial of a key figure in a prostitution scandal at a Zumba studio in Maine has gone through four days without a jury being selected. And it’s unclear if the process will resume Monday. A pair of appeals to the state supreme court delayed the trial of Mark Strong Sr. in Superior Court in Alfred. The defense is worried that the lengthy delays could cause potential jurors to turn against Strong even before jury selection is completed and the trial begins in earnest with opening statements and testimony. Jury expert Valerie Hans from Cornell University Law School says surveys show jurors hate delays. But she says there’s no research showing that they’d punish a defendant.
