Ronnie Oneal III committed a brutal double murder in Riverview, Florida, in 2018. He fatally killed his ex-girlfriend Kenyatta Barron and their 9-year-old daughter Ron'Niveya O'Neal with a hatchet. He also stabbed their 8-year-old son and set their house on fire. The son survived and testified against him in court. Ronnie Oneal was found guilty of two counts of first-degree murder, attempted first-degree murder, arson, and aggravated child abuse. He was sentenced to three consecutive life sentences without the possibility of parole, plus 90 years. The case and trial, in which he acted as his own attorney, received significant media attention due to its tragic nature and his unusual defense strategy.

This is different from Ron O'Neal (often confused due to similar names), who was an actor and director known for his role in the film "Super Fly".
