Sheriff: search for Savannah Guthrie’s missing mother could take years

Pima County Sheriff Chris Nanos said the search for Savannah Guthrie’s mother, Nancy, could take "maybe it’s weeks or months or years" and pledged that his team will not quit looking.

Authorities briefly thought they had a break after detaining delivery driver Carlos Palazuelos for questioning; he told officials he had no knowledge of Guthrie or her mother and was released.

Officers collected DNA evidence from Nancy’s residence that did not belong to anyone in "close contact" with her, and investigators are working to identify who it belongs to.

A SWAT team executed a search warrant at a home near Nancy’s property and at least four people were detained for questioning before being released; no arrests were made. She was last seen on Jan. 31 around 9:45 p.m. after dinner and was reported missing on Feb. 1. The FBI released a suspect description — a male about 5-foot-9 or 5-foot-10 with an average build — and increased the reward to up to $100,000.
