Summary based on the NamUs case record (MP43066) and 7 other sources
David Christopher Kempker, a 27-year-old man from Concord, California, went missing on March 12, 2018, under mysterious circumstances. Kempker was reportedly on a fishing trip in the Sherman Island area of Sacramento County with a friend when they became separated. However, his family doubts the fishing story, as Kempker did not have a fishing license or any equipment with him. The day after he went missing, his family reported him to the authorities when he failed to return home.

On March 14, Kempker's Toyota truck was found abandoned along a road off Highway 160 in the Sherman Island area. His beanie and vest were located near the vehicle, but there were no further clues to his whereabouts. Despite extensive searches in the area, no trace of Kempker was found. Since his disappearance, there has been no activity on his phone or financial accounts.

Kempker worked as an electrician in Truckee, California, and was known for his love of extreme sports and outdoor activities. His family continues to search for answers, and his case remains unsolved, with the Concord Police Department leading the investigation.
