MEDFORD - The children of a woman who was killed in the Medford pharmacy massacre filed a $20 million lawsuit this morning that names several defendants, including the Suffolk County Police Department. Jaime Tacetta was one of four people gunned down by David Laffer at Haven Drugs last June. The lawsuit filed on behalf of Tacetta's children names seven defendants, including drug manufacturer Abbott Laboratories. The suit claims the drug maker should have known its products were being abused. The suit also claims that police failed to properly investigate Laffer's gun license. It notes that while Laffer's guns were legally registered, a detective had warned the county's pistol licensing bureau about him months before the shooting. The doctor who provided Laffer with prescriptions and the owner of the pharmacy are also named in the suit. As News 12 Long Island has reported, Laffer is serving five consecutive life sentences for shooting four people at point-blank range and robbing the drugstore of thousands of pills.Laffer, wife get max sentences for roles in Medford massacreAccused Medford pharmacy killer, wife plead guiltyContinuing coverage: Medford pharmacy massacre
