The trial of the former Lee, Massachusetts, police chief was delayed a day because of health concerns, but is on track to begin Tuesday. Joseph Buffis is accused of extortion, and also of raiding a charity toy fund for personal use.

On Friday, Buffis’ attorney Lori Levinson told the court her client was going in for an MRI. In open court on Monday morning, she offered no details of his health, other than to say, “Mr. Buffis is prepared to go forward tomorrow.”

And so a pool of 80 potential jurors will be interviewed, and narrowed down to 12, plus 3 alternates. District Court Judge Mark Mastroianni says he expects that to take more than 2 hours, before moving on to opening statements.

Before jury selection gets going, Mastroianni may rule on the government’s plans to introduce evidence of other thefts for which Buffis is not charged. Mastroianni has already said prosecutors can offer evidence showing Buffis stole from the Lee Police Association.

Now he’ll decide whether the jury can hear about alleged theft from the bingo fund at Saint Mary’s Catholic Church. Buffis’ lawyer objects to the prosecution’s request, writing that “…another set of allegations, exhibits and witnesses will further confuse and taint the jury.”
