A Winslow man charged in May with allegedly sexually assaulting a student at the Waldo County Technical Center will face another charge of gross sexual assault stemming from the same incident, according to police.

Michael Gagnon, 47, of Smiley Drive, issued a summons Monday charging him with another count of gross sexual assault after police said he assaulted a 17-year-old girl at his home in Winslow. Gagnon, who was an automotive technology instructor at the technical center in Waldo, was charged in May for the same crime after he allegedly would leave class to take the girl on “test-drives” of the vehicle they were working on in class and sexually assault her in the vehicle.

Gagnon was put on leave from his position at Waldo Tech and as softball coach at Mount View High School in Thorndike following the arrest.

Gagnon pleaded not guilty in May to the first charge.

“It was revealed in the investigation that one of the incidents occurred at his residence in Winslow, and because of that, another charge was brought against Gagnon,” said Winslow Det. Ronald McGowen.

Under Maine law, it’s a class C crime for someone employed by a school district who has “instructional, supervisory or disciplinary authority over” a student under 18 years old to have sexual contact with the student. Gross Sexual Assault is a Class C felony that carries a penalty of up to five years in jail or a $5,000 fine.
