David Christopher Kempker, 27, of Concord, California, disappeared from the Sherman Island area of Sacramento County on March 12, 2018. He was reportedly on a fishing trip with a friend when the two became separated, but family members question that account because Kempker had no fishing license or equipment with him.

His family reported him missing the next day when he did not return home. On March 14 his Toyota truck was found abandoned along a road off Highway 160; a beanie and a vest were recovered nearby but no other clues emerged. Extensive searches turned up nothing, and there has been no activity on his phone or financial accounts since he vanished. Kempker worked as an electrician in Truckee and enjoyed extreme sports and outdoor activities.

Do you have any information about Kempker’s movements in the Sherman Island area on or after March 12, 2018?
