Initial findings don't link Garridos to other girls

ANTIOCH, California (CNN) - Investigators who completed their search of the California property belonging to kidnapping suspects Phillip and Nancy Garrido said initial findings do not connect the couple to the disappearances of two young girls.

But police said that they have not eliminated Phillip Garrido as a suspect in the decades-old cases.

Bone fragments found on the couple's property near Antioch could be human but are "far too old to be relevant in our cases," said Lt. Chris Orrey of the Hayward police department.

Teeth found on an adjacent property are most likely from an animal, she said. And some anomalies found by ground-penetrating radar uncovered "chunks of concrete, tree roots, and in one case a floor mat," Orrey said at a news conference.

Investigators had already found bone fragments at the property in unincorporated Contra Costa County, but have not said if they are human.

"Although nothing [was found] that would definitively link Phillip and Nancy Garrido to the disappearance of Ilene Misheloff or Michaela Garecht, we're going to continue to follow up on the evidence that we have recovered," Lt. Kurt von Savoye of the Dublin Police Department said at the news conference.
