The chairwoman of the House Oversight Committee says she's concerned by the situation at the Rhode Island Training School.  State Representative Patricia Serpa says it's troubling that children are at serious risk due to the inadequacies of a state agency.  In the aftermath of recent serious incidents, Department of Children, Youth and Families Director Trista Piccola says issues including security, personnel and youth services will be addressed.  Serpa says the committee will give DCYF the opportunity to put solutions into practice.
