Las Vegas investigators have identified a suspect in the 1989 killing of a 14-year-old girl by using the smallest set of DNA samples ever used to crack a cold case, the Las Vegas Review-Journal reports. Stephanie Isaacson went missing from Las Vegas after leaving her home to walk to school. Her body was found the evening of her disappearance; she had been sexually assaulted and strangled. Justin Woo, a local philanthropist, provided a donation that utilized new genome sequencing technology to analyze just 15 DNA cells that led to identifying Darren Roy Marchand as the suspected killer.
