K-9 Dolly and SACH O’Sullivan recently responded to assist the ATF Pittsburgh Field Office with a search warrant at a residence for alleged unlawful possession of explosives. Dolly alerted to a bag in one of the upstairs bedrooms, which contained grenade fuzes, grenade bodies, and rifle powder. K-9 Dolly also searched the exterior property and surrounding woods where she located a large storage container buried in the ground with only the top of the container showing. The container was removed from the hole in the ground and when opened revealed it contained numerous grenade fuzes and flash bangs that had been reported stolen from a business licensed by ATF to acquire and store explosives. The suspect worked at this business.
SACH O’Sullivan and K-9 Dolly also worked the Boston Marathon bombing investigation.
