Kathy Rigsby Portelli, 43, left a drug treatment session at Circles of Care in Melbourne, Florida, on July 21, 1998, and was never seen again. She had been struggling with drug and alcohol addiction and had a history of disappearing for days, which delayed a missing person report until her mother filed one on August 3, 1998, after Kathy missed her Social Security disability check for the second month in a row.

Investigators recovered some of Kathy’s belongings after she vanished. Her pager was found in Cocoa; when the family called it, a man said he had found the pager but would not give details. Her Social Security card turned up at a man’s home in Cocoa; he said she had left it there before she disappeared. Her ex-husband was investigated but no evidence tied him to the disappearance. Authorities consider her endangered and believe she may have been taken against her will.

Kathy was described as a Caucasian female, blonde hair, brown eyes, 5 feet 2 inches, 110 pounds, with scars on both wrists and her neck and two permanent plates in her jaw. If anyone knew Kathy, saw her on or after July 21, 1998, or has information about the pager or Social Security card discoveries, please come forward.
