A Florida teenager, Collin Griffith, has been charged with the first-degree murder of his mother, Catherine Griffith, after allegedly stabbing her to death. This incident follows his previous arrest in Oklahoma for fatally shooting his father in 2023, a case that was dropped due to self-defense claims. Polk County Sheriff Grady Judd described the teen as a 'psychopath' and emphasized the cold-blooded nature of the crimes, noting Griffith's lack of remorse and calm demeanor during both incidents. Witnesses saw Griffith dragging his mother by her hair before the stabbing, and inconsistencies were found between his account and the forensic evidence. Authorities are pushing to try Griffith as an adult, and efforts are underway to reopen the investigation into his father's death.
