Jeffrey David Daymude was 23 when he vanished from Satellite Beach, Florida, on October 19, 1978. Known as Jeff, he was last seen driving a dark blue 1964 Chevrolet and was accompanied by his dog. He was reportedly headed to Minton Park and has not been seen or heard from since.

Three days later the dog was found in northwest Palm Bay, with no sign of Daymude or his vehicle at that location. The Chevrolet has never been located. Investigators suspect foul play and the Brevard County Sheriff’s Office continues to treat the case as an active endangered missing person investigation.

If anyone has information about Jeffrey’s movements around October 19, 1978, the car or where the dog might have been taken, please share what you know with investigators.
