Paris Bennett had an IQ of 141 - the mind of a genius, the actions of a monster. He was 13 years old when he stabbed his 4-year-old sister Ella 17 times while she slept. He had planned to kill his mother first. Then decided death was too quick. He wanted her to suffer for the rest of her life. So he took the one thing she loved most. Under Texas law in 2007, a 13-year-old couldn't receive life imprisonment or the death penalty. He got the maximum possible: 40 years. In all the years since, he has never once apologized. In the video below, Paris sits across from Piers Morgan in prison and admits everything - including that he still loves his sister in the present tense. After it was over he called a friend and talked casually for 10 minutes about nothing in particular. Then he called emergency services, simulated panic, and pretended to perform CPR on his sister's body. When the police officer walked into the bedroom he muttered "oh my god." Paris heard it from the hallway. Said he felt like he was drowning in shame. Psychologists who evaluated him found a textbook psychopath. Zero empathy. Zero remorse. In all the years since, he has never once apologized to his mother for what he did. His mother sat beside him during the interview. Said his entire childhood revolved around him. Said he was loved by everyone. Said she still couldn't understand where the feeling of abandonment had come from. Paris said he spent his whole childhood feeling completely alone. A genius who calculated exactly how much pain he could cause and chose accordingly. Is Paris Bennett a product of something that broke inside a child, or was the monster always there waiting for the right moment?
