Court documents say criminal charges against the Vermont son of a New York prison worker who helped two convicted killers escape have been dismissed.

The Burlington Free Press reports (http://bfpne.ws/2gwOZXN ) 23-year-old Tobey Mitchell of Shelburne was cleared Friday of charges that included aggravated first-degree domestic assault. He had been accused last November of choking his wife.

Chittenden County Deputy State's Attorney Susan Hardin said Monday that her office dropped the charges after Mitchell successfully completed all required counseling.

Attempts to reach Mitchell's lawyer on Monday were unsuccessful.

Tobey's mother, Joyce Mitchell, helped Richard Matt and David Sweat break out of New York's maximum security Clinton Correctional Facility last year. Matt was later shot dead by police; Sweat was wounded.

She is serving an up to seven-year prison sentence.
