Bloody and battered after an elite patrol teamed up with state police to take him down. They used thermal technology to track his movements, and then unleashed a canine in the morning to sniff out and subdue the brutal killer. State Police Officers revealing what they believe was the key to his capture. They were able to move in quietly, they had the element of surprise, cavalcante did not realize he was surrounded until that had occurred. That did not stop him from trying to escape. He began to crawl through thick underbrush, taking his rifle with him as he went. One of the customs and Border Control teams had a dog with them. They released the dog. Dana the community that was locked down for two weeks can finally rest easy. Local residents saying how relieved they are, they wont have to worry about a killer on the loose. I flipped the lights on and off when he flipped the lights back, that was the moment my wife was already on 911 but i was like, he is downstairs, call 911 right now.
