"Leo just happened to be in the wrong place at the wrong time" #ForensicsRealCSI #Forensics #TrueCrime #Crime When 12-year-old Leo Ross is found fatally stabbed in Birmingham’s Trittiford Mill Park on his way home from school, police suspect a 14-year-old but need forensics to prove he is the killer. There's little information about whether Leo was targeted, and finding a murder weapon in such a vast area is an immediate challenge. The 4km park has numerous pathways, a marshland and no CCTV coverage. Body cam footage from first responders proves to be crucial.
