Police are searching the Antioch home of Phillip Garrido hoping to find evidence related to the disappearances of two children from the 1980s.

Authorities from the Hayward and Dublin Police Departments, investigating the disappearances of Ilene Misheloff and Michaela Garecht, are searching the backyard compound of Phillip Garrido, believed to have held missing child Jaycee Lee Dugard for 18 years up until her discovery one month ago.

At a press conference Tuesday morning, Lieutenant Chris Orrey with the Hayward Police Department told reporters numerous similarities between the Jaycee Lee Dugard case and the cases of Misheloff and Garecht led authorities to obtain a search warrant to scour the grounds of Phillip Garrido's Contra Costa County home.

Dublin Police Department's Lieutenant Kurt von Savoye said the break in the Jaycee Lee Dugard case brought new light and new hope into the cases of the missing two girls.

"There is no eyewitness who can say with certainty that she was abducted and the physical evidence to date has been limited," von Savoye said in regard to the Misheloff case.

Authorities say they have not interviewed Jaycee Lee Dugard, and nothing Jaycee has told authorities with the FBI in other interviews have led them to believe there may be a connection between suspect Phillip Garrido and the other two missing girls.

At an afternoon press conference, the mother of one of those two girls told reporters the eyewitness to her daughter's abduction said Garrido had similarities to Garecht's abductor.

"She has said he [Garrido] looks just as much like the kidnapper as anyone she's seen," Garecht's mother, Sharon Murch, said Tuesday afternoon.

Michaela Garecht, born in January 1979, disappeared from Hayward, California on November 19th, 1988.

Ilene Misheloff, born in March 1975, disappeared from the streets of Dublin on January 30th, 1989. A $90,000 reward was offered for information relating to her disappearance.

Both girls were believed to be abducted by a Caucasian male driving an American-made gold car, according to case information.

Convicted sex offender Phillip Garrido, along with his wife Nancy Garrido, are currently on trial for the abduction of Jaycee Lee Dugard, who went missing from her South Lake Tahoe-area home in 1991. Dugard was found living with Phillip Garrido in August after a parole officer received a tip from UC Berkeley police, who spotted Garrido with Dugard and two young girls on the school's campus handing out religious literature. The two girls spotted alongside Garrido are now believed to be the children of Jaycee Lee Dugard, fathered with the convicted sex offender during her time at Garrido's Antioch home.
