Katherine met Anthony Lowe on a dating website, but he was not the man he appeared to be online. Using a fake profile, he tricked her into a relationship which ended with her murder in her own home.

Simon Gilchrist was a hard-working young man from a loving family, but his life changed once he started a relationship with Caroline Mawhood.

But Caroline was prone to bouts of heavy drinking and violent behaviour – which, one day, went too far.
