This week on Florida's Fourth Estate we take a deep dive into DNA. News 6 investigator Mike Deforest tells us about a fascinating case in which an accused killer was found because his cousin put his DNA online. It took a clandestine mission to find the suspect and gather his DNA. The question is, do cases like this open Pandora's box? Also, we break down the video of a 6-year-old's arrest. The police officer has been fired for using Zip Ties to subdue the little girl and put her in his patrol car. Floridians also showed love this week. A man jumps into a canal to save a stranger. a woman was having a seizure when she crashed into the water. Her car was sinking as one man jumped in to rescue her. All of this and more on this week's Florida's Fourth Estate.
