Judith Judy Nesbitt, 42, was shot and killed on November 26, 1980, in Newport Beach, California. She was showing her family’s boat, the Felicidad IV, to a prospective buyer at the Marina Dunes Yacht Anchorage when the man followed her into the boat’s sleeping quarters. A violent struggle occurred and the man shot Judy in the head, killing her instantly, then stole her credit cards, checkbook, and cash before fleeing.

The case remained unsolved for decades. Investigators in 2002 obtained a DNA profile from hair roots found at the scene, but it did not match any entries in CODIS. In 2018 newer DNA extraction from remaining hair shafts produced a more complete profile, and genetic genealogy work identified the buyer as Kenneth Elwin Marks. Marks had died in 1999, so he could not be prosecuted, but the identification ended a long period of uncertainty for Judy’s family.

Does anyone have memories of Judy, the Felicidad IV, or the Marina Dunes Yacht Anchorage in 1980 that could add context to this case?
