The unknown DNA investigators obtained in the case of Nancy Guthrie’s abduction is going to be helpful when investigators have a suspect, CNN Chief Law Enforcement and Intelligence Analyst John Miller said.
Officials have not been able to determine who the DNA belongs to, according to Pima County Sheriff Chris Nanos.
This means it didn’t match the “known contributors,” Miller said, meaning the people who have been around or inside Guthrie’s house for other reasons.
It’s also “not somebody who’s been convicted of a felony or arrested on a serious charge where that DNA would be in the FBI system,” Miller said. Investigators would have run it through that database, he said.
