anybody in that residence? >> sublet's former boss is reached on his cell phone. in a stroke of luck, he and his family are not at home, but he warns agents of an extensive gun collection in his basement, now at sublet's disposal. >> i think there were over 20 firearms that he had access to. they included handguns, they included shotguns, they included high-powered rifles. >> if we had tried to storm the place, somebody was going to get hurt. so the decision was made to wait him out. >> special agent in charge, carl stankovich, joins more than 120 units on the scene. that residence was located on 15 acres of property that was pretty much wide open. >> using his vantage point, sublet opens fire on law enforcement. >> i could hear rounds hitting light poles. we could hear things pinging off every time that he would fire. you could hear at different points rounds hitting different places. >> power and water to the home are cut.
