Bone Fragment Near Garrido's Property Likely Human

Sept. 9, 2009— -- A sheriff's spokesman says a bone fragment found next to the home where Jaycee Dugard was held captive for 18 years by Phillip Garrido is probably human.

Contra Costa County Sheriff's Department spokesman Jimmy Lee cautioned that is not unusual to recover Native American remains in the area.

But the Contra Costa County Sheriff's Department has asked the state crime lab to perform DNA tests on the fragment, which was found on Aug. 31.

Garrido took care of the neighboring house while it was vacant and sometimes camped in the yard in 2006.

He and his Nancy Garrido face 29 felony counts for what he allegedly did to Dugard. Both husband and wife have pleaded not guilty.

Investigators are still looking for links between Phillip and his wife Nancy Garrido, the couple accused of kidnapping and imprisoning Dugard and other missing children in the area.

"We are taking very seriously the possibility that he could be connected to some others," San Francisco FBI Special Agent Joseph Schadler told ABCNews.com.

Rod Garecht told ABC News that police have contacted him looking for any connection between Jaycee's 1991 abduction when she was 11 and the 1988 kidnapping of his 9-year-old daughter Michaela.

"Anything to keep her in the news and keep people talking about her is good," Garecht said today.
