Two teenagers, 13-year-old Cade Poulos and 15-year-old Triston Stephens, recently committed suicide in their school hallways. People have been searching for answers in the aftermath but there are no definite explanations for why teenagers commit suicide, according to Kimberly Parker, director of children's services at a counseling center. The setting of a suicide could be related to concerns about the environment, an attempt to avoid intervention, or an impulsive act.
