A Florida teenager has been charged with murder in the fatal stabbing of his mother, less than two years after he was arrested for fatally shooting his father but never charged, authorities said.
Polk County Sheriff Grady Judd said during a Wednesday press briefing that the teen had previously allegedly threatened to kill his mother before Sunday’s “cold-blooded murder.”
The stabbing occurred after the teen, 17-year-old Collin Griffith, and his mother, 39-year-old Catherine Griffith, were seen having an altercation outside a mobile home in Auburndale, according to Judd.
“There were witnesses outside the mobile home that actually saw Collin drag his mother into the house by the hair on her head,” the sheriff said.
Griffith called 911 Sunday evening to report that his mother “fell on a knife” and was bleeding from the neck, Judd said. The teen reportedly said his mother had lunged at him with the knife when she fell on it during a prolonged fight inside the home, according to Judd.
