DNA technology solves decades-old murder cases in US

Advances in forensic genetic genealogy and modern DNA analysis have led to breakthroughs in two long-unsolved homicide investigations in the United States.

In Spokane, Washington, authorities have arrested 74-year-old David T. for the 1986 strangulation of Mary Ann Turner. Investigators utilized forensic genetic genealogy to link DNA found under the victim's fingernails to the suspect and his deceased brothers. A decisive breakthrough occurred when investigators obtained a DNA sample from the suspect via a returned envelope related to a separate investigation involving a stolen vehicle.

In Las Vegas, Nevada, a separate case involving a man found strangled with a telephone cable in December 2005 has seen a significant development. While a DNA profile was recovered from the victim's stolen vehicle in Tennessee in 2006, it could not be matched to any database at the time. Recently, the sample was submitted to the specialized laboratory Othram, where modern analytical methods established a familial connection to a potential suspect.
