Diana Zalewski of 30 Rosemont Ave. was charged Thursday with first-degree sexual assault, fourth-degree sexual assault and four counts of risk of injury to a minor. Court officials said Zalewski is also known as Diana Pare and Diana Pinette.

Senior Assistant State’s Attorney Ronald Dearstyne did not reveal much information from the arrest warrant affidavit for Zalewski’s arrest, which is sealed by the court, but asked for a high bond for the defendant.

"These facts, if they are true, are some of the worst facts I’ve ever seen in this type of risk of injury case," Dearstyne said, adding that the state will seek "substantial incarceration" if Zalewski is found guilty.

Dearstyne described the activities that led to Zalewski’s arrest as "an ongoing situation in the home" and said there is medical evidence to support the charges.

Assistant public defender James Sward said Zalewski has not had contact with the two minors for the last year. He said the alleged incidents predated Zalewski’s convictions in 1999 for two counts of risk of injury to a minor and one count of carrying a dangerous weapon.

Court documents indicate the alleged incidents that led to the charges occurred between January and August 1999.

Court Intake Assessment Referral Specialist Charles Cyr said Zalewski received nine-month prison sentences for each of the convictions. In addition, she was convicted in 2001 of violation of probation and served a year in jail.

Judge James M. Bentivegna said he took the circumstances of the charges and Zalewski’s criminal record into account in setting the $200,000 bond, which was higher than Cyr’s recommendation of $50,000 and a bit lower than the $300,000 bond Dearstyne asked for.

Zalewski is scheduled to return to court on Feb. 5.
