Sandra Lynn Kerby, 52, was last seen on July 10, 1999, leaving her daughter’s home in northeast Fresno around 11:30 a.m. to go shopping. She was driving a white 1993 Ford Explorer; the SUV was found abandoned in the River Park Shopping Center parking lot two days later with her purse and keys inside. Investigators noted the driver’s seat had been adjusted for someone taller than Sandra, a detail that fed concerns about foul play.

Sandra was a devoted wife, mother and a teacher at Gibson Elementary School, and her disappearance is described as highly out of character. Suspicion later focused in part on her husband, Frank Kerby, after he gave inconsistent accounts of his whereabouts the day she vanished and a call from his cell phone was traced to Reedley, about 30 miles from Fresno. Authorities searched the couple’s home six months later and found diary entries indicating Sandra knew of her husband’s extramarital affair; Frank later proposed to that girlfriend and in 2006 had Sandra declared legally dead to obtain the home title.

The case is treated as a potential homicide and remains unsolved. Does anyone with memories of River Park, or who knew Sandra or the Kerby family in 1999, have information that could help investigators?
