Michelle Gloria Adam, 36, vanished from South Kona in the summer of 1998. She was last seen at her Milolii Beach Lots home on June 13 and reportedly drove off in her 1997 Toyota Celica. Her husband, Richard Louis Adam, later said she told him she needed her space and he assumed she had gone to their second property in Hawaiian Ocean View Estates; the Celica was found parked at that second home two days after she was last seen. He did not report her missing until June 17.

In October 1998 the Milolii Beach Lots house was destroyed in a suspicious fire; authorities have not definitively linked the blaze to Michelle’s disappearance. In January 1999 detectives reclassified her case from missing person to homicide and conducted a two-day search in Milolii and Hawaiian Ocean View Estates that produced no evidence or remains. Michelle was described as 5 feet 1 inch, about 85 pounds, with long straight brown hair and brown eyes when she disappeared.

Does anyone with knowledge of Michelle, those properties, or activity in South Kona in June 1998 have information that could help this cold case?
