18. BTK

BTK was the sadistic self-selected pseudonym of Dennis Rader, a serial killer who slaughtered ten people in Kansas between 1974 and 1991. The letters denote “Bind, Torture, Kill”, and Rader used the grisly acronym to sign off his correspondence to the media and the police. Eventually, however, his attention-seeking behavior was his downfall. In 2005, he sent a floppy disk to a news station containing a Word document he had edited.  Hidden data in that document contained vital clues that ultimately led investigators to Rader.

17. The murder of Krystal Beslanowitch

On December 15, 1995, 17-year-old Krystal Beslanowitch was found battered to death on the banks of the Provo River in Utah. But police investigators were unable to solve the crime until 18 years later. In 2013, a new DNA collection device called the M-Vac was used on the rock that had been used to murder the teenager. It recovered 21 nanograms of genetic material which belonged to one Joseph Simpson. He was subsequently convicted of aggravated murder.

16. The disappearance of the McStay family

Joseph and Summer McStay were living in Fallbrook, California, with their two sons, 4-year-old Gianni and 3-year-old Joseph Jr, when they inexplicably vanished from their home on February 4, 2010. For years, investigators believed that the family had gone missing in Mexico. But on November 11, 2013, a motorcyclist located their remains in two shallow graves in a desert near Victorville, CA. A year later, Chase Merritt, Joseph’s business partner, was arrested after his DNA was recovered from the family car. His murder trial is currently scheduled for February 2018.
