In 1984, the decomposed remains of a woman wrapped in plastic were found in remote Wizard Wells, Jack County, TX.  Experts posited that she was a young white woman, but without any identification, no fingerprints, and no corresponding missing persons reports, she could not be identified. Fast forward nearly 40 years – when IGG would be used on her bones to identify her as Roberta Mumma.  Roberta hailed from the Lancaster, PA area and was believed to have died around age 25.  Her death is considered a homicide, and the Jack County authorities and the Texas Rangers are seeking information about her case.

Upscale Chevy Chase, MD does not see a lot of violent crime. But that changed in 2001, when loving wife and mom Leslie Preer was beaten to death in her own home in a shocking crime.  Investigators could find no motive for the murder, but certain aspects of the crime scene directed investigators’ attention to Leslie’s husband as the prime suspect.  After all, it was very unlikely that a stranger had broken into the house, killed Leslie, and attempted a clean-up. But they could not pin the crime on Carl Preer, and the case stalled.  Not until the Montgomery County PD cold case unit embraced IGG did they find a name of a suspect – one who had been under their noses the whole time.

In 1990, Madison County IL authorities recovered the remains of a nude young woman in a soybean field. She had some articles of clothing and jewelry with her, but no identification.  Investigators could not identify her, and she was buried in a church cemetery with a headstone that called her Jane Doe.  But they had the foresight to retain some physical evidence, and with the advent of IGG, were able to use that evidence to locate living relatives of Jane Doe.  She was Wynona Nadine Michel – but her identity is just part of the mystery.  She is now the subject of an active homicide investigation. Who killed Wendy Michel?
