(CNN) A man who beat a transgender woman for using the women's restroom was found guilty of a hate crime.

Fred Constanza was convicted in an Oregon court for first-degree bias crime, second-degree assault and harassment for the August attack on Lauren Jackson, a transgender woman.

Jackson was visiting Agate State Beach Park near Newport, Oregon, on the day of the attack. She stopped to use the women's restroom -- and that's when Costanza walked over 100 yards across the park to confront her, multiple witnesses told Newport police.

Lauren Jackson, a transgender woman, told police a man beat her for using the women's restroom. Her attacker was found guilty of a hate crime this week.

Costanza hit Jackson 10 times, police said. She told them he was holding her hair back to prevent her from escaping.

Newport police found Jackson bleeding from her face with a broken jaw after Constanza had fled the scene. He was arrested later that day.
