Fifteen-year-old Sean Walsh paces in a robotic loop around the lower level of his family’s Camelot Drive, Howell, home.
He circles the table in the family’s great room, pauses by his sister Shannon, then punches her in the head.
“I can’t fight back,” she says later. “How are you going to punch an autistic kid in the nose?”
Only minutes later, Sean hugs his mother, Michelle, and his 17- year-old sister. He tussles with his father, Howell Mayor Robert F. Walsh, and laughs.
