Lois Lee Robinson, 78, was last seen in Valley County, Montana, on January 1, 2007. Described as a Caucasian woman with gray hair and blue eyes, she was about 5 feet 4 inches and 130 pounds. Details of her disappearance are scarce and the case remains unsolved.

Investigators note several complicating factors: Robinson used multiple known aliases — Lois Jackson, Nadine Jackson, Lois Otto, Nadine Otto, and Lois Lee Robinson-Otto — and she frequently traveled in an RV. Authorities have considered that she might be living under a different name, but no substantial leads have been developed despite searches and ongoing efforts by the Valley County Sheriff’s Office.

The case remains listed in missing persons databases in hopes of new information. If anyone has information about Lois Robinson’s whereabouts or her travels around the time she disappeared, contact the Valley County Sheriff’s Department.
