(WXYZ) - Bonnie Steele is on a mission to prevent another teen from taking his or her life.
Her son Brandon killed himself last month. She found him in his bedroom.
There were no outward signs of trouble. Nothing unusual on his Facebook page. Bonnie and her family learned too late that Brandon had posted dark messages on his Twitter account.
Bullying at school may have been a factor, but it is not an excuse in this tragedy.
Students at Howell High School where Brandon was a student have made suicide prevention their cause, in his name.
