On Friday, April 15, 2016, the police showed up at a semi-detached house on Dawson Avenue in Spalding, Lincolnshire. It was the home of the Edwards family, 49-year-old Elizabeth and her two daughters, 13-year-old Katie and 14-year-old Kim, whom no one had seen for a couple of days.

After receiving no response, the officers forced their way inside the home, and uncovered a crime that sent chills down the spine of even the most seasoned detectives.
