Jeffery Roosevelt Crider, a 31-year-old U.S. Navy veteran, was last seen January 4, 1991, in Vallejo, California and was not reported missing until October 17, 1994. That gap of more than three years before authorities were notified is a central unexplained detail of the case; the reasons for the delay are not stated.

Crider was described as an African-American male, 5 feet 11 inches and 170 pounds. Distinctive features include webbed toes on both feet, a scar on his left leg, and small extra fingers attached to both pinky fingers. He sometimes used the alias Kenneth Wilson and his first name might appear spelled Jeffrey in some records.

Few additional facts about his last known movements or possible leads are available and the Fairfield Police Department is handling the investigation. If anyone knew Jeffery Crider, his whereabouts, or has information that could help, please contact the Fairfield Police Department.
