Kristina Joanne Porco was 16 when she left her family’s condominium in the Woodlake Villas complex on Hilton Head Island, South Carolina, the night of November 29, 1986. A curfew argument with her mother preceded her departure at about 10:30 p.m.; she took no belongings or money. She called a friend from a nearby payphone asking to spend the night, and when that was refused said she might sleep by the apartment complex pool. During that call she mentioned a taxi that kept driving by slowly. That phone call was the last known contact.

A short time later the friend checked the pool area and Kristina was gone; her red sweater was found draped over a lawn chair. Her savings account, holding about $100 to $200, was never touched.

Investigators have pursued leads over the years. A missing-person flyer for Kristina was found in the Ohio home of person of interest Christopher J. Below in 1992; he was living in South Carolina in the late 1980s and has been linked to other disappearances, but has not been charged in Kristina’s case. Kristina’s mother searched for years and believed remains might be in the North Forest Beach area, but no evidence has been found. Does anyone on Hilton Head from that time have memories or information that could help explain what happened that night?
