In August 1999, two teenage girls, JB Beasley and Tracie Hawlett, were found dead in the trunk of a car on the side of the road in Ozark, Alabama.
They had been raped and shot in the head. The DNA found at the scene didn’t match anyone in the police database, so the case went cold.
The killer, Coley McCraney, was 26 years old at the time and went on to live a normal life. He even started a church and became a bishop with children.
Nearly 20 years later, he was arrested and put on trial for the murders of the two girls.
Coley was caught after the DNA from the crime scene was sent to Parabon Nanolabs, a company in Virginia that can predict how a person might look based on their DNA.
After Coley was arrested, the police took a DNA sample from him, which perfectly matched the semen found at the crime scene.
