Lavena says her 17-year-old son, Trevor’s, anger is out of control, and despite seeing mental health professionals for years, his behavior is growing more aggressive and defiant. She says Trevor screams, curses and breaks things during his rages and has even threatened to shoot people -- and never shows remorse for his actions. She says she fears he could snap and kill her, her husband, her 5-year-old twins -- or become the next school gunman.
