Details of Disappearance

Portelli was last seen in Melbourne, Florida on July 21, 1998. She attended a drug treatment session at Circles of Care and was last seen leaving the facility with two men. She has never been heard from again. Her pager was later found in Cocoa, Florida.


Due to her substance abuse history, Portelli had a history of dropping out of sight for days at a time. Her mother reported her missing on August 3, after she didn't pick up her Social Security disability check for the second month in a row.


According to her family, Portelli grew up in a religious home and considered becoming a minister, but became addicted to drugs as a young adult after she met her husband. They had three children together. The two girls lived with Portelli's mother at the time of her disappearance, and their brother was in foster care.


Portelli had a violent relationship with her ex-husband and he was investigated for possible involvement in her disappearance, but police could find no evidence to implicate him. Her case remains unsolved. Investigators believe Portelli may have been take against her will.
