Heather Marie Riggio, 20, disappeared from North Miami Beach, Florida, on May 6, 2007. She was last seen leaving her uncle’s home and getting into a white SUV driven by Clifton Boggess, a man she called her sugar daddy. Boggess, who has a criminal history including an attempted murder conviction, is the primary suspect; he has not cooperated with investigators and refuses to provide details about Heather’s whereabouts.

Heather had struggles before she vanished: a background that included exotic dancing and involvement with people tied to drug activity, prostitution and possibly human trafficking. She also faced a pending felony drug possession charge when she went missing. Friends reported seeing her in the Homestead area about a week after she was reported missing, but despite searches — including in the Everglades — no trace of her body has been found.

Police suspect foul play and continue to view Boggess as someone with crucial information. Heather’s family is still seeking answers. Does anyone who knew Heather or saw her around May 2007 have information that could help the investigation?
