Ruth Marlene Mello, 47, was last seen on July 4, 1989, near the base of the 10th Street Bridge in Marysville, California, after an argument with an acquaintance. She had traveled from the Sacramento area to visit her daughter shortly before her disappearance. At the time she went missing she was wearing a red and black terrycloth shirt, yellow cotton stretch pants, red Vans shoes and was known to wear eyeglasses.

Reports say her case is considered suspicious but very few details have emerged to clarify what happened. She may also have used the last names Moore or Tolk. Investigators pursued various leads but the case remains unsolved and authorities continue to seek information.

If anyone remembers seeing Ruth around Marysville on July 4, 1989, or has information about her whereabouts, please contact the Yuba County Sheriff’s Office.
