Forensic Files - Purebread Murder - Collection 1 - Episode 32 - Netflix, Season 14 - Episode 1 - In the series - A not so typical perp is identified by a footprint in a hamburger bun. Yes. I said a hamburger bun. With our victim's ex-boyfriend being the most probable killer, a couple of Big-Mac hamburger buns give investigators what they need to get the right guy. "Can I have extra cheesy, lettuce, tomato, jalapenos and could you please hold the foot impressions please Sir? Thank you!" Matt also hits y'all with a little serious talk about addiction. Make somebody smile today. Thanks!
