Katherine Schmittler, 41, was last seen at her Kahuku residence on the North Shore of Oahu on the morning of February 1, 2008, at about 9:00 a.m. She had an appointment that day at Kaiser Hospital but never arrived. Her failure to show up and the complete lack of communication were immediately out of character and prompted family and friends to report her missing.

Katherine is described as a Caucasian female with blond or strawberry-blond hair and blue eyes, 5 feet 5 inches tall and about 140 pounds. When last seen by friends she was reportedly wearing blue denim shorts and a yellow shirt. Family members, some traveling from as far as Japan, came to Oahu to help with searches. The Honolulu Police Department opened a missing persons case, but the initial investigation produced few leads and the case later grew cold.

What details about Katherine’s routine, acquaintances, or movements around Kahuku in early 2008 might help explain her disappearance?
