David Ruenzel, a 60-year-old writer and educator from Oakland, California, was shot to death while hiking in Huckleberry Botanic Regional Preserve on November 25, 2014. His body was found in the afternoon by a woman who reported hearing gunshots; Ruenzel had been shot at least twice and shell casings were recovered at the scene.

Witnesses reported seeing two men on the trail shortly before the shots. Police called them persons of interest: one described as late 20s or early 30s, thin, with dreadlocks, high cheekbones and a narrow face; the other described as about 6 feet tall, 240 pounds, out of shape, clean-shaven with short hair. Investigators believe robbery may have been a motive because Ruenzel was known to carry valuable items while hiking. The East Bay Regional Park District offered a reward, but no arrests have been announced.

Ruenzel taught English and journalism at the Athenian School in Danville and was active in educational journalism; his family and community continue to seek answers. If anyone has information about that afternoon on the trail, please come forward.
