Timmothy Pitzen was just 6 years old when he disappeared in 2011. His mother, Amy, lied about a family emergency, took him out of school, and left. The two were spotted together at a zoo, a water park and a resort. But two days later, Amy checked into a hotel alone. She died by suicide, and the only clue she left behind was a note claiming Timmothy was safe and he would never be found. Eight years after Timmothy mysteriously vanished into thin air, an impostor told police he was Timmothy, and he had escaped kidnappers. Police doubted his story ... but if this wasn't him, where is the real Timmothy Pitzen? His father and Aunt speak out for the first time.
