39-year-old Katherine Griffith was found the day before with a stab wound to her neck. Police in Hamptons, Florida, suspect her son, 17-year-old Colin Griffith, of the crime.
The teen called 911 himself: he stated that he had an argument with his mother, after which she "fell on the knife". Police arrived and saw the woman's body, as well as her son's - he was calm, cold-blooded and covered in blood.
Criminalists immediately said that the story described by the guy is not believable. Griffith himself, police say, showed no sympathy for his dead mother, only stating, "I know my rights. I need a lawyer."
It turns out that the teen shot and killed his father last year. Griffith claimed at the time that the man had come at him with a knife and that he acted in self-defense.
In 2023, the charges against the teen were dropped because they couldn't prove murder, not self-defense. Griffith now faces life in prison on the charges.
