A major breakthrough might be just hours away in the Nancy Guthrie case.

Officials investigating Nancy Guthrie’s disappearance are closing in on the “porch guy” spotted on the missing 84-year-old’s security camera, according to a former FBI agent.

Maureen O’Connell told “Megyn Kelly Show” listeners Tuesday that she is “75 percent” certain authorities are “getting close to” the individual seen on Savannah Guthrie’s mom’s porch the night she disappeared.

O’Connell predicted that, when the person is detained, the “floodgates shall swing open.”

Megyn Kelly replied, “That’s big news. That’s huge — big if true, as the kids say.”

O’Connell did not elaborate further on her claim, via sources, that officials are “close to pulling this case together.”

She did, however, cryptically say, “Things are happening.”

As for what has taken more than five months to make an arrest, O’Connell explained, “You’re gonna have the greatest defense attorney in the world handling this case, whoever takes [it]. So you have to operate under the assumption that a couple big chunks of your evidence may get tossed.”

Nancy was abducted from her Tucson, Arizona, residence in the middle of the night on Feb. 1.

Ten days later, the FBI and the Pima County Sheriff’s Department released footage of a masked and armed individual on Nancy’s porch.

The person appeared to tamper with the doorbell camera in the chilling footage.

Savanah, 54, dubbed the “absolutely terrifying” video “unbearable” to watch in her first sit-down interview on the family tragedy in March.

“I can’t imagine that is who she saw standing over her bed. I can’t,” the journalist told colleague Hoda Kotb. “I wake up every night in the middle of the night. And in the darkness, I imagine her terror. And it is unthinkable, but those thoughts demand to be thought.”

Savannah, who has acknowledged that Nancy may already be “gone,” has continued to beg for her mom’s return.

Most recently, she tearfully told “Today” show viewers about her “agony” and said, “We cannot be at peace [until she is found]. … Please do the right thing.”

The NBC personality also addressed recent reports that a ransom note, believed to be credible, allegedly alerted authorities to Nancy’s inadvertent death.

A message from the same I.P. address has previously referred to the matriarch as “safe but scared.”

Savannah said she had “no comment,” emphasizing that she is “not involved” in the networks’ coverage of her missing mom.
