Pima County

A 20-year-old driver and two of his passengers have died after police say he was racing another driver in Tucson when he slammed into another vehicle Sunday night.

Savannah Guthrie shared a picture of flowers at the home of her missing 84-year-old mother, Nancy Guthrie, saying in part, "We feel the love," and "Please don't stop praying and hoping with us."

It's been more than a month since 84-year-old Nancy Guthrie disappeared from her Tucson-area home, and for the first time since she went missing, her daughter, NBC "Today" show host Savannah Guthrie, was seen out in public on March 2, laying flowers outside Nancy's home with her brother and sister.

It's been more than a month since Nancy Guthrie, Savannah Guthrie's mom, disappeared from her Tucson-area home. According to Fox News, the case has been handed off to a task force featuring homicide detectives and FBI agents.

The Pima County Sheriff's Office says it is "refocusing resources" to detectives assigned to the case, and reviewing surveillance video, as the search for Nancy Guthrie hits the one-month mark.  

Savannah Guthrie made another plea to her mother's suspected kidnapper on Feb. 27, via a video posted to social media with the caption "please - be the one that brings her home."

On Thursday, newly-released video from a neighbor's Ring camera showed a dozen cars passing through the area on the same morning that Nancy Guthrie disappeared from her Tucson-area home.

As the search for Nancy Guthrie continues, there have been lots of speculation online on who may be responsible, and it is having an impact on some people.

It has been weeks since Nancy Guthrie went missing, and on Feb. 25, cameras capture the moment agents return to the woman's home and backyard casita. It is unclear why investigators made a return. FOX 10's Steve Nielsen has more.

New law enforcement activities were spotted at the Tucson home of Nancy Guthrie. The 84-year-old mother of 'Today' show host Savannah Guthrie has been missing for over three weeks.
