AUBURN – Lewiston Mayor Lionel Guay on Monday sat in court as six women and six men, plus two alternates, were picked to serve as the jury in his upcoming trial on charges of sexual touching and assault.

Guay was in Androscoggin County Superior Court for nearly 4 hours Monday afternoon, dressed in a dark, pinstriped suit. Justice Ellen Gorman set Guay’s trial for Sept. 25. It’s expected to last three days, she said.

Guay conferred throughout the process with his Lewiston lawyer, Jennifer Ferguson. He sat through jury selection for three other defendants before it was his turn at 3:15 p.m. He was excused an hour and a half later.

His case stems from allegations by a teenager. She claimed Guay touched her breasts on Feb. 11, 2005, touched her buttocks a month later, then kissed her on the mouth on Sept. 26.

Guay is charged with three counts of unlawful sexual touching and four counts of assault. Each of the charges is a class D misdemeanor, which carries up to a year in jail and a fine of up to $2,000.

State prosecutors in Augusta lodged the charges one week before Guay’s re-election last November to a second two-year term as mayor.

Pre-trial motions in the case included a request by prosecutors that Guay’s lawyer share information about his defense, including office time cards. An appeal by the defense climbed to the Maine Supreme Judicial Court, which was turned away on the grounds that it was premature.

Assistant Attorney General Leanne Robbin said she has received the documents she requested but declined to explain their significance.

Before Guay’s jury was selected Monday, Justice Gorman quizzed prospective jurors about whether they had any personal or professional relationships with Guay, any of the lawyers or potential witnesses. Before jury selection, each person in the pool of more than 60 jurors was asked to fill out a questionnaire dealing with sexual abuse.

When asked whether they had heard or read news coverage about the case, about three dozen of the would-be jurors stood to show they had. Eight said they already had formed opinions about the case.

Five members of the jury pool said they were concerned about whether they could be fair and impartial. Gorman called more than a dozen of the pool members into her chambers, along with the lawyers, to further probe them about their ability to sit on a jury.

The final jury was selected by 4:45 p.m.
