'Unbelievable': Possible new evidence in Nancy Guthrie kidnapping discovered near her home

Investigators may have found stunning new evidence that could be linked to the disappearance of Nancy Guthrie, the mother of "Today" show co-host Savannah Guthrie.

Nancy Guthrie disappeared from her home in Tucson, Arizona, 11 days ago. Local investigators have not released any information about a potential suspect or a person of interest in the case. On Tuesday, video from Guthrie's doorbell camera captured images of an individual dressed in gloves and a ski mask breaking into her home.

On Wednesday, CNN reported that investigators found a black glove near Guthrie's home, which some speculated could tie the kidnapper to the case.

Wallace Zeins, a former NYPD hostage negotiator, described the glove as an "unbelievable piece of evidence" for investigators during an interview on CNN's "Erin Burnett OutFront."

"They may not have the perp on this one, but they will find out where that glove came from," he said.
