Mom shared chilling final post before allegedly being killed by son, 17, a year after he killed his father

A mother shared a haunting final social media post before she was allegedly killed by her son, a year after he killed his father.

Catherine “Cathy” Griffith, 39, was found dead in her Auburndale home on Sunday after her 17-year-old son, Collin, called police.

Authorities arrived to find Griffith with a fatal knife wound to her neck, while Collin, covered in blood, stood outside the home, as reported by the New York Post.

Police reported that Collin showed “zero emotion” after allegedly killing his mother.
