Nickalas Kedrowitz was 13 years old when he killed two children. Now, he’s sentenced to 100 years in prison for the crime. Kedrowitz confessed to killing his siblings in 2018, and was found guilty in 2021 on two counts of murder for their deaths. Prior to sentencing, the teen received treatment at a mental hospital, according to his mother. He was evaluated to determine if he was competent to stand trial and if he could be tried as an adult, according to prosecutor Ric Hertel.
