They didn't realise he couldn't be trusted until it was too late - #DEAD2ME

Described as one of the most brutal murders in Cardiff's history, the death of Katherine Smith at the hands of her boyfriend Tony Lowe is etched into the memories of all who knew her. The mum of one first met Tony on an online dating site. Nearly twenty years her senior, Lowe manipulated and belittled Smith before killing her in a jealous rage. With testimony from those closest to each case, #DEAD2ME will explore the stories of ten couples from all over Britain whose relationships were borne out of the digital age. While these relationships started promisingly enough, they would all take a turn for the tragic, and in each case a running commentary provided by their digital dialogue and postings reveals how and why.
