Milam vanished the night of Sept. 15, 1972, after leaving a university sorority event in Terre Haute, about 80 miles southwest of Indianapolis. She who was found bound and gagged in her vehicle on campus the next day. she died of strangulation. Investigators used a new DNA testing and genealogy technology. Jeffrey Lynn Hand, the killer, died in a gunfight with police in 1978 during an attempted abduction. He was shot and killed by a police officer. Hand, who would have been in his early 20s at the time of Milam’s death, had a violent history that included murder, stalking and attempted abduction. The police now ran a “reverse paternity” test using DNA from Hand’s children and comparing it to DNA evidence from the murder scene.
DNA has not only impacted areas such as paternity testing and genetics, but it has literally revolutionised the field of criminology and improved the functioning of the criminal justice system. A person’s DNA is the same in all areas of their body, it can’t be altered or modified in any way. No DNA is the same between two people, with the exception of identical twins.
