David Scott Keller, 39, was last seen April 9, 2005, when he set out on a fishing trip from Freeport, Texas, with two companions, Austin Childs and John Zimmerman. They departed in Zimmerman’s 28-foot pleasure boat with a yellow Labrador Retriever, ice chests, life jackets and other fishing gear and planned to return the following day.

The boat was later found capsized in the Gulf of Mexico. A seat cushion and several life jackets were recovered floating nearby, but there was no sign of Keller, Childs or Zimmerman. Authorities believe the vessel may have struck an object that could have cracked the hull, and the incident is considered a tragic accident. Despite extensive searches, no trace of the three men or the dog has ever been found and all are presumed lost at sea.

If anyone was on the water off Freeport around April 9, 2005, or saw a 28-foot pleasure boat in trouble that day, any information could help bring answers to the families.
