Answer:
Back in April of 2016, two 14-year-old lovers became the youngest double murderers in England’s history. Kim Edwards and her bf, Lucas Markham, killed Edward’s mother, 49 year-old Elizabeth, and younger sister, 13-year-old Katie, in a brutal stabbing that took place in Edward’s home in Spalding, Lincolnshire. It was Markham who stabbed Edwards’ mother and daughter, however, a jury found Edwards equally culpable for the crime, plotting their deaths three days before with Markham at a McDonalds near her house.
