Mary Lou Black, 72, and her husband Billie were last seen leaving their home in the 2400 block of Pacific Street in Atchison, Kansas, at about 8:15 a.m. on September 11, 2009. They drove a light blue 1990 Honda Civic, four-door, Kansas plate AWX 605 — described as having paint missing from the hood and a loud exhaust system that dangled from the undercarriage. Concern grew when the couple did not return and a check of their house found lights left on and personal items inside, including both driver’s licenses, a checkbook with cash, and Billie’s insulin from the refrigerator.

Mary Lou was in the advanced stages of Alzheimer’s disease and stood about 5 feet 1 inch, 115 pounds, with gray hair and brown eyes. Billie also had significant health problems and had been Mary Lou’s primary caregiver. Authorities say there is no evidence of foul play; one theory is the vehicle entered the Missouri River, accidentally or intentionally, but no concrete evidence supports that. Neither the couple nor the Civic has been found.

Does anyone who lived in the area in September 2009 remember seeing that Honda Civic or either of the Blacks that morning?
