Nancy Guthrie: Savannah makes emotional Mother's Day plea for missing mom

Savannah Guthrie, the daughter of Nancy Guthrie and host of the "Today" show, is renewing a call for help to locate her missing 84-year-old mom. 

What we know:

The post, shared on Instagram, was a tribute to her mom on Mother's Day, as it nears 100 days since her disappearance earlier this year. 

"mother, daughter, sister, Nonie - we miss you with every breath. We will never stop looking for you. We will never be at peace until we find you.

We need help. Someone knows something that can make the difference. Call 1800CALLFBI. You can be anonymous and the reward remains available.

Please keep praying.
Bring her home."

The post features images and videos of Nancy and the family. Savannah urged anyone who may know something regarding her mom's disappearance to call the FBI.

Meanwhile, the investigation is no closer to finding Nancy, with both federal and local law enforcement pointing the blame at each other. 

"Typically our homicide team comes out when we have a homicide, a body," Pima County Sheriff Chris Nanos said on Feb. 1, the day Nancy was reported missing. 

Recently, FBI director Kash Patel said the Pima County Sheriff's Department (PCSD) didn't let them help for four days, which he claims delayed getting critical evidence. He also told FOX's Sean Hannity in an interview that the department was trying to keep the FBI out. 

"The first 48 hours of anyone's disappearance are the most critical," Patel said. "Here's how these cases work. It is a state matter. It’s a state and local law enforcement matter. What we the FBI do is say hey, we're here to help."

According to Patel, the sheriff refused the FBI's help on the DNA, sending the evidence to a lab in Florida instead of Quantico's lab. 

"We would have analyzed it within days and maybe gotten better information or more information," Patel said. "Our lab is just better than any other private lab out there, and we didn't get a chance to do that."

In response to Patel's interview, Nanos said a member of the FBI task force was there the night of her disappearance working with PCSD. The sheriff said the department and the Guthrie family promptly told the FBI about the situation, and was not delayed. 

The backstory:

Nancy Guthrie went missing on the night of Jan. 31 and was reported missing on Feb. 1 when she didn't show up for church. Since her disappearance, the FBI released footage of her alleged abductor at her doorstep.

On May 9, when questioned if the sheriff's department is closer to finding Nancy Guthrie, Sheriff Nanos told Fox News,"We are."

What you can do:

Savannah Guthrie says her family is offering a $1 million reward for the recovery of Nancy. Anyone with information should contact the FBI at 1-800-CALL-FBI.

The Pima County Sheriff's Department has also set up a tipline where the community can submit information. An online form is available for tips.
