Law enforcement investigating the disapearance of “Today” show host Savannah Guthrie’s mother have blocked off a road near Nancy Guthrie’s home in Arizona. A parade of sheriff’s and FBI vehicles, including forensics vehicles, passed through the roadblock Friday night. The roadblock is about 2 miles from the house. The Pima County Sheriff’s Department says the activity is part of the Guthrie investigation but declined to detail specifics. The 84-year-old 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.
