Local and federal authorities said Friday they're "aware of a new message" regarding the disappearance of "Today" show co-hostSavannah Guthrie's mom,Nancy Guthrie, as the high-profile search continues.
"Investigators are actively inspecting the information provided in the message for its authenticity," the Pima County Sheriff's Department said in a post onsocial media.The FBI also posted asimilar statementon social media. It's unclear what kind of message it is.
Inanother social media post, a little after 4 p.m. local time Friday, the sheriff's department said that investigators were "conducting follow-up" at the home of Nancy Guthrie and "surrounding areas."
Two law enforcement sources told CBS News on Saturday that investigators are "developing good information" but that "nothing is imminent."
The road in front of the Guthrie home was restricted, the sheriff's department said, and late last night, what appeared to be a dark-colored SUV was towed from the home. The sources said the car was Nancy Guthrie's, and that investigators were examining it for possible fingerprints and potential other clues. Investigators also removed a camera from the roof of the home.
The FBI and the sheriff's office are continuing to canvass the neighborhood and are tracking down vehicles that were seen on surveillance cameras in the area the night Nancy Guthrie disappeared.
Pima County Sheriff Chris Nanos spoke with CBS News correspondent Jonathan Vigliotti about the case on Friday, but was guarded about details, including how the abductor may have entered the home or if there were signs of forced entry. The sheriff's office said Saturday they had no planned briefings.
Investigators believe Nancy Guthrie is "still out there"after her family reported her missing to authorities on Sunday, after not finding her at home when she didn't show up for church that morning.

The sheriff's department has said no suspect or person of interest has been identified in the case. Authorities are treating her disappearance as a criminal matter.
The FBI also announced a$50,000 rewardfor information leading to Nancy Guthrie's recovery or the arrest and conviction of the people involved in her disappearance.
A ransom note that investigators said they're taking seriously included a deadline of 5 p.m. Thursday, said Heith Janke, the special agent in charge of the FBI's field office in Phoenix. The note demanded payment in bitcoin, and if a transfer wasn't made, then a second demand was for next Monday, Janke said.
On Wednesday night, Savannah Guthrie appeared with her brother, Camron Guthrie, and sister, Annie Guthrie, in a video saying they're "ready to talk" but that they need to know their mother is alive.
"We need to know, without a doubt, that she is alive and that you have her. We want to hear from you, and we are ready to listen. Please, reach out to us," Savannah Guthrie said.
Camron Guthrie alsomade an appeal on Thursdayon social media for their mom's return, saying, "Whoever is out there holding our mother, we want to hear from you."
