The father of the gunman in the Sandy Hook Elementary School killings has met with a Connecticut official and agreed to help find missing school and medical records that could shed more light on the tragedy.
Peter Lanza met for about an hour on Thursday with the leader of a state panel that is investigating the massacre of 20 first-graders and six educators in Newtown in December 2012 by Lanza's son, Adam.
Hamden Mayor Scott Jackson, chairman of the Sandy Hook Advisory Commission, told the Connecticut Post that he met with Lanza in Stamford. The commission is meeting Friday.
A spokesman for Peter Lanza said he had no comment.
Commission members have said they need more information about Adam Lanza's mental state before making recommendations to change mental health policy.
