Details of Disappearance
Billie and his wife, Mary
, disappeared from Atchison, Kansas at 8:15 a.m. on September 11, 2009. They left their home in the 2400 block of Pacific Street in their light blue four-door 1990 Honda Civic with the Kansas license plate number AWX 605 and never returned. Their vehicle has never been located. It has paint missing from the hood, and its exhaust system is loud and dangles from the undercarriage.
After their disappearances, the lights were found turned on in the Blacks' home. Billie and Mary's driver's licenses were there, as well as a checkbook and some cash, and Billie's insulin was in the refrigerator.
Billie and Mary grew up together in Orrick, Missouri and graduated high school there. Billie went to engineering school, joined the Air Force, and eventually became a plant manager at an Atchison aluminum factory; Mary attended the University of Central Missouri and later taught school. They had one son together.
By the time of their disappearances, both Billie and Mary had severe health problems. Billie was stressed from having to care for Mary, and told their son it would be better for him if his parents weren't around.
Authorities and members of the Blacks' families believe they're no longer alive. One theory is that they drove, accidentally or intentionally, into the Missouri River. Little evidence is available in their cases, however, and their disappearances remain unsolved.
