Summary based on the NamUs case record (MP32247) and 2 other sources
David Allen Standish, a 63-year-old man from Mill Valley, California, went missing on December 8, 2015. He was last seen aboard his houseboat docked in Richardson Bay, a location where he lived. The police had contacted Standish on the morning of December 7 for a non-criminal matter, which was the last known interaction with him.

Standish’s family had last spoken to him in November 2015, and when they were unable to reach him, they requested a welfare check in January 2016. Authorities visited his houseboat on January 2 and 3 but found no signs of Standish. His boat was empty, with no indications of a struggle, and his wallet and journal were still onboard. However, his Zodiac dinghy, which he used to travel between the shore and his houseboat, was missing.

Authorities suspect Standish may have fallen into the bay, but the exact circumstances of his disappearance remain unclear. His case remains open, and investigators continue to seek answers regarding his fate.
