An investigative reporter has claimed that Tommaso Cioni, Nancy Guthrie's son-in-law, was spotted at her home as a search for her continues.
According to the reporter, Tommaso was seen entering the garage with law enforcement, but it is unclear why he was at the house amid the manhunt.
The Guthrie family, including Tommaso, has been cleared of suspicion in the search for the missing 84-year-old woman, police said.
Tommaso was the last person to see Nancy before she disappeared, but authorities have stated that he should not be wrongly scrutinized based on that.
