David Laffer Pharmacy Shooting: Gun Bureau Was Warned Before NY Killings

HAUPPAUGE, N.Y. -- Police reports indicate a New York detective warned a licensing bureau to take a suspect's guns five months before he killed four people during a pharmacy drug robbery.

Commissioner Richard Dormer says in a statement that "any information of acts of violence or illegal drug use" brought to Suffolk County police's attention would have been forwarded to the Pistol License Bureau.

Dormer says that would have prompted an immediate investigation and gun license suspension.

Dormer and pistol bureau officials declined interviews.

Laffer pleaded guilty to first-degree murder for the June bloodbath.

Newsday recently spoke to the killer, who said that he didn't expect to kill anyone during the robbery. "I did not know I'd use the gun. Absolutely not," Laffer said. The plan was to steal pills his sick wife could no longer afford, and the gun was to ensure the couple didn't get jumped in the process. The first shot that went off was an accident, Laffer claims.

Suffolk County District Attorney Thomas Spota doesn't buy that story.

"The video clearly shows he deliberately raises his backpack, aims and shoots," Spota said. "He doesn't flinch, he doesn't jump or move in any way as anyone would if a weapon fired accidentally." Head over to Newsday for more.
