HARTFORD, Conn. (AP) - Former educators in the Connecticut town where 20 children and six adults were shot to death in an elementary school are pushing back against a state report that was critical of how the shooter's education was handled.

The former Newtown officials gave state senators Thursday a 22-page rebuttal to the 2014 report by the state child advocate's office on the upbringing and education of Adam Lanza.

The 20-year-old Lanza, who grew up in Newtown, killed 26 people and himself at Sandy Hook Elementary School in December 2012.

The former Newtown officials cited the school system's efforts to help Lanza with his mental problems when he was in school and called his mother a "tremendous obstacle" to those efforts.

The child advocate's office is defending its report.
