"It's a shocking, sickening tragedy of a child who was completely dependent on adults and the community and public system to protect him," Eagan said. "Our role at the [Office of the Child Advocate] and the child fatality review panel is to examine how such a tragedy could have occurred and how a child of his age can be found in such a devastating and shocking condition. All children are vulnerable but a child with significant disabilities, who is unable to advocate on his own behalf, is particularly vulnerable to abuse."
