DNA Tech Boosts Cold Case Hunt
16 Apr
Summary
- FBI uses new technology to analyze mixed DNA evidence.
- Sample recovered from the home of Nancy Guthrie is being re-examined.
- Investigators anticipate a six-month processing time for the DNA.
Law enforcement officials are leveraging advanced technology in the ongoing investigation into the 1999 disappearance of Nancy Guthrie. The FBI is now analyzing a significant DNA sample recovered from Guthrie's Tucson residence, a case that has remained cold for years. This mixed DNA evidence, previously handled by a private lab and the Pima County Sheriff's Department, presents a complex challenge as it contains genetic material from multiple individuals.
Sheriff Chris Nanos has indicated that the meticulous process of separating and identifying the relevant DNA strands could take up to six months. Despite the intricate nature of the sample, federal agents are applying their latest technological tools in an effort to identify the perpetrator of Guthrie's abduction. Approximately two dozen investigators from both the Pima County Sheriff's Department and the FBI remain actively engaged in the case, underscoring the sustained effort to find answers and bring closure to the family.
