Nathan Warren Florence II, 48, vanished from Shingletown, California, on August 24, 2010. He was last seen traveling with Donna Sholberg; the pair were reportedly headed to Reno, Nevada, a trip of about three hours, but neither person was ever heard from again and both remain missing.

Florence was described as 6 feet 6 inches, 225 pounds, with graying blonde hair and blue eyes. He had multiple tattoos, including a parakeet and other birds on his chest and arms, and a skull and spiderweb on his right elbow. The Shasta County Sheriff’s Department investigated but released few details explaining their disappearance.

The case remains open and investigators continue to seek information that could clarify what happened to Florence and Sholberg. If anyone knew Nathan’s routines, travel plans, or saw him or Donna around August 24, 2010, please come forward with what you know.
