The office has filed a lawsuit against the Newtown schools and John R. Reed, the interim school superintendent, Courthouse News Service reported Tuesday. In court papers, state officials say Newtown has not responded to a subpoena in March requesting Lanza's records from the public schools he attended.
Lanza attended Newtown public schools. On Dec. 14, 2012, the 20-year-old shot and killed his mother, Nancy, at their home in Newtown and then drove to the school, where he gunned down 20 children and six adult staffers before taking his own life.
In court papers, the Child Advocate said it is required to investigate "the death of a child in out-of-home care or whose death was due to unexpected or unexplained causes." The Child Fatality Review Panel investigation's aim is to find ways to identify children at risk of violence, officials said.
