WEBSTER (AP) -- Federal agents say they've traced the buyer and seller of weapons used in the ambush shooting of four western New York firefighters, but they can't release those details because the investigation is ongoing.
Special Agent Mike Campbell of the Bureau of Alcohol, Tobacco, Firearms and Explosives says Wednesday agents have turned over the information to state police. Troopers are investigating how ex-convict William Spengler Jr. got the firearms used in Monday's pre-dawn attack that killed two firefighters and severely injured two others near Rochester.
Spengler spent 17 years in prison for the 1980 hammer slaying of his grandmother. Convicted felons are prohibited from owning firearms.
Police say Spengler had a semiautomatic rifle, shotgun and revolver. He killed himself with a shot to the head after trading fire with a town of Webster police officer.
