Melquisedec Betancourt, 32, was found dead on August 3, 2017, inside a car near the Sarasota Airport in Bradenton, Florida. Investigators determined he had been shot three times while seated in the driver’s seat. Witnesses reported seeing a man flee the scene and discard a weapon; that person was identified as 36-year-old acquaintance Karrie Lee Sanderson III. The firearm was recovered, and Sanderson’s DNA was found on it. Security footage captured Sanderson running through the parking lot immediately after the shooting. Sanderson initially told investigators he acted in self-defense, saying Betancourt had been shooting at him, but evidence introduced at trial contradicted that account. Sanderson later admitted to shooting Betancourt but continued to claim self-defense. The conviction of Sanderson for second-degree murder followed a trial in which prosecutors emphasized the investigation’s speed and the physical evidence.

Does anyone have information about Betancourt’s final movements that day or witnessed activity near the airport lot on August 3, 2017?
