HAYWARD -- Nearly two years after Hayward police mounted a major search of the property near Antioch belonging to Phillip and Nancy Garrido in hopes of finding clues related to the disappearance of Michaela Garecht, investigators finally talked to the couple, who maintained their innocence.

Investigators spoke with each of the Garridos for more than two hours last week.

"It was nothing earth-shattering," Sgt. Corey Quinn said. "Both denied having anything to do with Michaela's disappearance."

Philip Garrido, a twice-convicted kidnapper and rapist, previously told El Dorado County investigators that while he is responsible for at least three more abductions and dozens of date rapes, he had nothing to do with the high-profile abduction of 9-year-old Michaela in 1988.

Hayward investigators remain interested, however, and plan to look at evidence taken from the Garridos' compound in the next week and to conduct more interviews with the pair.

Shortly after Jaycee Dugard surfaced in August 2009, police from various agencies converged on the Garridos' compound, where Dugard was held for 18 years.

Hayward police conducted what was called the most extensive search in the history of the department because of strong similarities to the 1988 disappearance of Michaela, snatched from a Hayward grocery store's parking lot.

Police camped out on the Garridos' property for a week, using cadaver dogs and ground-penetrating radar, hauling trash out by the truckload while searching for evidence that could connect the couple to Michaela's disappearance.

Nothing was found.

At the time, Hayward police wanted to speak to the Garridos, but a judge ruled that law enforcement agencies not involved with Dugard's case would have to wait until after the trial.

That ended in June when Phillip Garrido, 60, received a sentence of 431 years to life in prison, while Nancy Garrido, 55, was sentenced to 36 years to life in prison, all in accordance with their guilty pleas made in April.

Quinn said Hayward investigators will meet with El Dorado County inspectors next week to "go over more things," before conducting more interviews with the Garridos.

"They have so much stuff up there, we need to decipher what we think is of interest or not," Quinn said. "I can only imagine what they have -- all of Jaycee Dugard's life, and Garrido's past."
