People That Helped Solve Their Own Murders: #3 Physics Student Mattew Pyke

Mattew Pyke was a modest and easy-going physics student.

In 2008, 20 year old Mattew and his girlfriend, 21 year old Joanna Wilton, were living in Nottingham, United Kingdom. They were gamers and ran a online forum for the game boy series "Advance Wars". On September 9th, Joanna came home from work to find Mattew, stabbed to death. She called the police and when they arrived that discovered "D A V", written in blood on the side of Mattew's computer. Despite Mattew being stabbed over 80 times, he had wrote the name of his killer, David Heiss. 

21 year old German office worker David Heiss met Joanna in 2007 through their forum. He would spent up to 8 hours a day chatting on the forum. David became obsessed with Joanna and sent her emails declaring his infatuation with her. 3 months before the murder, Joanna and Mattew had come home from a vacation to find David waiting for them. David returned a month later, this time the couple was annoyed and sent him on his way and blocked him from the forum. Before he left, David told the couple that they would never be together.

In May of 2009, David was found guilty of Mattew's murder and sentenced to life in prison. He will have to serve at least 18 years for the savage murder.
