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 said the activity was part of the Guthrie case. But it said the FBI requested that it not release further information. No new details were available early Saturday.
Guthrie, 84, was reported missing on Feb. 1. 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.
Authorities have expressed concerns Guthrie’s health because she needs daily medication. She is said to have a pacemaker and has dealt with high blood pressure and heart issues, according to sheriff’s dispatcher audio on broadcastify.com.
Investigators have studied surveillance video, sorted through thousands of tips and submitted DNA and other evidence for laboratory analysis.
The FBI said it has collected more than 13,000 tips since Feb. 1, the day Guthrie was reported missing. The sheriff’s department, meanwhile, said it has taken at least 18,000 calls.
On Tuesday, authorities released footage showing an armed, masked person at Guthrie’s doorstep on the night she was abducted. The videos — less than a combined minute in length — gave investigators and the public their first glimpse of who was outside Guthrie’s home in the foothills outside Tucson.
Experts say the video could contain a mountain of clues. ___
