Sheriff’s, FBI and forensics vehicles passed through roadblocks 2 miles from missing 84-year-old woman’s home

Law enforcement investigating the disappearance of Today show host Savannah Guthrie’s mother, Nancy, sealed off a road near her home in Arizona late Friday night.

A parade of sheriff’s and FBI vehicles, including forensics vehicles, passed through the roadblock that was set up about 2 miles (3.2km) from the house.

The Pima county sheriff’s department said the activity was part of the Guthrie case, but also said the FBI requested that it not release further information.

Guthrie, 84, was reported missing on 1 February. Authorities say her blood was found on the front porch of her Tucson-area home. Purported ransom notes were sent to news outlets, but two deadlines for paying have passed.
