TUCSON, Ariz. (AP) — Law enforcement investigating the disappearance of “Today” show host Savannah Guthrie ’s mother sealed off a road near Nancy Guthrie’s 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 (3.2 kilometers) from the house.

The two agencies also tagged and towed a Range Rover SUV from a Culver’s restaurant parking lot. The restaurant is just over 2 miles from Nancy Guthrie’s home. This activity took place at the same time the sheriff’s office closed a road just north of the Guthrie home.

The Pima County Sheriff’s Department confirmed Saturday that a federal court-ordered search warrant was executed at the home Friday in connection with the Guthrie case. The warrant was based on a lead the agency had received. No arrests were made.

A traffic stop was also conducted, and while someone was questioned, no arrests were made, the sheriff’s office said.
