Police carried out a fresh search on the home of Jaycee Lee Dugard kidnap suspect Phillip Garrido Tuesday, reportedly looking for evidence in two unsolved abductions from the 1980s. A statement from the Contra Costa County Sheriff's Office said police investigators from the towns of Hayward and Dublin had converged on Garrido's property in Antioch, east of San Francisco. No further information was revealed but local media reports said the search was related to the disappearance of schoolgirl Michaela Garecht, who was abducted from outside a Hayward grocery store in 1988. Police from Dublin were also searching the property looking for links to the disappearance of Ilene Misheloff, 13, who vanished in nearby Dublin in 1989. Dublin and Hayward are roughly 60 miles (96 kilometers) south of Antioch. The development comes after police said a bone fragment found in an earlier search of Garrido's home and a neighboring property was 'probably human.' Garrido is accused of abducting Dugard in 1991 when she was 11 and holding her prisoner for 18 years in a secret compound hidden behind his home. The convicted rapist allegedly fathered two children with his victim, who was discovered alive last month. Garrido and his wife Nancy Garrido have pleaded not guilty to a 29 count indictment which includes charges of kidnapping and rape.
