Police end search of Gilgo Beach murder suspect's home after seizing "massive amount of material"

Police have completed their search of Gilgo Beach murder suspect Rex Heuermann's Long Island home, said Suffolk County District Attorney Raymond A. Tierney in a news conference Tuesday afternoon. 

Tierney said police found "approximately 279 weapons" in the "cluttered" residence, including "quite a few long guns" and 92 handgun permits. In addition to the weapons, a "massive amount of material" was removed from the home, but Tierney declined to offer more details. 

Many of the guns were found inside a walk-in vault in Heuermann's basement, police said Tuesday. Suffolk Police Commissioner Rodney Harrison told CBS New York that the vault had a large iron door, but said it was "not a soundproof room."
