The Connecticut Post found that the gun shop where the mother of the Sandy Hook shooter, Adam Lanza, had purchased the firearms used by Lanza in the Newtown, CT, elementary-school murders had a history of deficient compliance with gun-shop rules and regulations. FOIA records showed that the deficiencies mainly related to poor record-keeping. The newspaper cited one instance in which the gun shop was unaware that a gun had been stolen from its premises.
