Summary based on the NamUs case record (MP27798) and 3 other sources
Donnel Sears, a 29-year-old man, went missing on January 30, 1982, from Madeira Beach, Florida. Donnel, along with his friend Michael Franzese, embarked on a 10-foot Styrofoam sailboat two days prior, on January 28, 1982. They were last seen leaving the area to sail in the Gulf of Mexico, but neither of them nor the boat was ever recovered. The disappearance was officially reported on January 30.

Despite search efforts by local authorities, no signs of the men or their boat were found. The circumstances surrounding their disappearance remain unclear, and both men are still classified as missing. The case remains unsolved, with little information available beyond the initial details. Their disappearance remains a cold case, and the community continues to seek any potential leads.
