The Santa Clara County Sheriff's Department reported Monday that some bones found last week in the woods above Los Gatos most likely are not those of Jeanine Harms, a 42-year-old woman who disappeared from her Los Gatos home in 2001.

A comparison of the skull's teeth and dental X-rays of Jeanine Harms are what reportedly made the determination.

Sheriff's spokesman Deputy Terrance Helm said the bones appear to belong to a woman and are probably about 2 to 3 years old.

A hiker alerted authorities after he found a skull near the Lexington Reservoir last Thursday. The skull was fairly intact, including the upper jaw and teeth.

A pelvic bone was also discovered and appears to be that of a woman between the ages of 20 and 35, Helm said.

Two days after the bones turned up, family and friends of Harms gathered in Los Gatos to dedicate a park bench in her memory.

Harms was last seen on July 27, 2001 leaving the Rock Bottom Brewery in San Jose with a male acquaintance. While her case was long investigated as a missing persons case, Los Gatos/Monte Sereno police eventually deemed the disappearance a homicide, which remains actively under investigation.

Last week's discovery wasn't the first time human remains were found in the Santa Cruz Mountains near Los Gatos. In 1995, the bones of 16-year-old Russell Jordan, a Los Gatos High School student slain by a classmate in 1982. Jordan's remains weren't identified until last March with the help of DNA technology.

DNA evidence also identified the skull of 7-year-old Xiana Fairchild, a Vallejo girl reported missing in December 1999. Her skull was discovered in January 2001.

The most recently discovered bones were sent to an anthropologist, who is working on a profile to determine the best possible age and nationality of the woman, Helm said.

The Santa Clara County Coroner's Office is not commenting on the case at this time.
