Spacey is accused of groping an 18-year-old man in 2016 at the Club Car Restaurant and Bar on the island. The young man is the son of former Boston news anchor Heather Unruh.

Last week a judge denied Spacey’s request to not attend the arraignment.

Legal analyst Jennifer Roman, a former Middlesex County assistant district attorney, told WBZ-TV she doesn’t believe Spacey’s case will reach a trial.

“I think Kevin Spacey is going to plead to a lesser charge,” Roman said. “I think ultimately he’s going to plead it down. He won’t plead to a felony. He’ll plead to some misdemeanor and the case will be resolved that way. I don’t see the case going to trial.”
