This undated photo provided by the Florida Department of Children and Families shows Gabriel Myers. Myers, a 7-year-old foster child in Florida, hanged himself in 2009. Post-mortem investigations determined that he had been a victim of sex abuse perpetrated by an older boy, had touched some of his classmates in sexually inappropriate ways, and was on several powerful psychotropic medications. Recent high-profile cases of child sex abuse have roused national revulsion against the adults who perpetrated them. Rarely mentioned is the sobering statistic that more than one-third of the sexual abuse of America's children is committed by other minors. (AP Photo/Florida Department of Children and Families)
