Antolin Garcia-Torres has been charged with her murder, but her body hasn't been found.Friday's discovery of female remains in San Benito County hasn't discouraged volunteers. "It gets hard at times, of course," volunteer Kelli Wilkins said. "You know, like with what happened yesterday.

The search headquarters are at Burnett Elementary School in Morgan Hill.
