Daniel LaPlante is an American murderer who was convicted of killing Priscilla Gustafson and her two children back in 1987 when he was only seventeen years old. LaPlante was a very troubled kid, having a history of breaking into people's homes and taking their possessions. He even broke into the house of an ex-love interest, lived in her walls for two months, and tormented her and her little sister with tapping sounds and mysterious writing on their walls. He is currently serving multiple life sentences for his crimes.
