Federico Ventura Supnet, 76, vanished from Oasis in Riverside County on April 5, 1997, while visiting the Agua Tech fish farm with family. He left the residence to use the restroom, then walked into a nearby vineyard and did not return. Supnet suffered occasional disorientation and memory loss, spoke primarily Ilocano with limited English and Spanish, and was unfamiliar with the area.

At the time he disappeared he had no identification or money. He was reported wearing blue jeans, a red and black acrylic sweater, a green polo shirt, and white Reebok sneakers, and carrying a plastic bag with a lighter and cigarettes. Despite extensive searches and an investigation by the Riverside County Sheriff’s Department, no trace has been found.

Could anyone who worked at or visited the Agua Tech fish farm or the surrounding vineyards on April 5, 1997, remember seeing Federico or anything unusual that day?
