The former chair of the Tisbury select board has received six months of pre-trial probation connected to allegations of trespassing and assault late last year.

Christina Colarusso was arraigned in Edgartown District Court Friday with Judge Benjamin C. Barnes presiding over the case. As long as there are no new charges against Ms. Colarusso during her probation, her case will automatically be dismissed in October, Judge Barnes said.

Police issued a criminal complaint against Ms. Colarusso in December after she allegedly trespassed on a Steamship Authority ferry docked in Vineyard Haven on Nov. 25

She was subsequently issued a second summons for allegedly assaulting a police officer who was trying to serve her with the trespassing citation.

On the morning of Nov. 25, Ms. Colarusso allegedly left Martha’s Vineyard Hospital, where she was sectioned, and broke onto the M/V Aquinnah steamship vessel, according to court documents.

Later that day, Ms. Colarusso allegedly flagged down a police officer driving down Main street, at which point the officer told her she’d be served with a trespass notice, Tisbury police wrote in their report.

Police said Ms. Colarusso appeared to be “having a mental episode of some kind” and appeared “not in control of all her faculties.” The report alleges that she made a series of vulgar, nonsensical statements before striking the officer on the buttocks with an open hand. The officer then transported her back to the hospital, according to the report.

Ms. Colarusso was elected to the Tisbury select board in 2023, edging out incumbent Abbe Burt by just three votes. She stepped down in January after being absent from meetings since September.
