Donald Nader, 46, of Grass Valley, California, was last seen about September 1, 2016, at his home on Lawrence Way in the Alta Sierra Estates area. His disappearance was treated as suspicious from the start and was later reclassified as a potential homicide after investigators executing a June 2018 search warrant on the residence uncovered evidence suggesting a violent struggle inside the home.

Authorities conducted a three-day search of the property and sought witness statements, including from Nader’s wife, who later became a fugitive after arrests in California and Idaho. Despite those efforts, Nader’s whereabouts remain unknown and no conclusive evidence has been found to determine what happened to him.

Anyone who knew Donald, his movements around early September 2016, or who has information about the residence or people connected to the household is asked to contact investigators.
