When 17-year-old Thomas Griffiths’ girlfriend ended their relationship, what happened next shocked an entire community. In this episode of Murder at My Door, we examine the chilling case of a teenage killer who murdered his girlfriend and staged the scene to look like a suicide. What first appeared to be a tragic death quickly unravelled into something far more sinister. Monster Among Us explores manipulation, deception, and the disturbing reality that sometimes the most dangerous person isn’t a stranger — but someone trusted, someone known, someone right at the door.
