Circumstances of Disappearance:
Unknown. Her photo is shown
age-progressed to 33 years. She was last seen leaving her home in the Woodlake Villas condominium complex on Hilton Head Island, South Carolina on
November 29, 1986. She left the house after an argument with her mother, and called a friend to meet her by the condominium pool. When the friend arrived, there was nothing there but Porco`s red sweater. Porco left on foot and took no money or clothes. Her savings account - between $100 and $200 - hasn't been touched.
Porco has never been seen again. Foul play is suspected in her disappearance.
