Authorities in Nancy Guthrie disappearance collecting DNA from employees

Authorities are taking DNA samples from hired workers around Nancy Guthrie’s Arizona home as the desperate search for Savannah’s mom continues.

This revelation indicates that DNA was possibly found inside her house or around the crime scene and authorities will use these samples to either eliminate suspects or give investigators a fuller picture of what might have occurred, per Fox News.

Since the 84-year-old was reported missing on Feb. 1, law enforcement has made it clear that they are “actively looking at everyone” as a suspect and taking all leads seriously.

On Tuesday, FBI released disturbing photos of an “armed individual” in a mask at Nancy’s front door.

The suspect appeared to tamper with the camera on her front porch, according to cops.

“We’re actively looking at everybody we come across in this case. Everybody. We would be irresponsible if we didn’t talk to everybody,” Pima County Sheriff Chris Nanos previously said in a press conference Feb. 5.

Nanos also confirmed that cops talked to the Uber driver who drove Nancy to her daughter Annie Guthrie and husband, Tommaso Cioni’s Tucson, Ariz., home for dinner the evening of her disappearance.

“It’s so cliché, but everybody’s still a suspect in our eyes. That’s just how we look at things and think as cops. Does that mean we have a prime suspect? No,” Nanos explained, adding that “the family’s been very cooperative” and “done everything” asked of them.

During a press conference on Feb. 3, FBI Phoenix special agent Heith Janke confirmed the existence of a ransom note with two deadlines. The first deadline was set for Feb. 5 at 5 p.m. local time, while the second was set for Feb. 9 at 5 p.m.

TMZ founder Harvey Levin revealed the chilling threat the suspected kidnappers made in their ransom note sent to the outlet.

“I’ll read you one line from the ransom note we received,” Levin told CNN Monday. “And they say, ‘It is in the best interest of everyone to have this completed as soon as possible.’

“This was way back when the first ransom note was issued.”

The legitimacy of the message has not yet been verified and sources tell Page Six the family still has not been given any proof of life.

Savannah and her siblings have issued several desperate pleas on social media to Nancy’s alleged kidnappers — offering to pay the ransom in one of them.

However, as of Monday, the ransom remains unpaid.
