Killing Them Softly

Richard Overton led a double life, marrying whilst already married. It’s a scam he led for a year and a half, but his downfall led to divorce from his first wife and an annulment from his second. Around 20 years later when his third wife collapsed and died, Overton was once again playing the double act: his wife’s cause of death was recorded as “unknown”, but he knew different. He stated they had a loving relationship, when in fact, he’d been slowly poisoning her to death. His undoing came in the form of a floppy disk and fragments of a secret and encrypted diary.

Wives and Lies

Audrey Marie Hilley’s husband, Frank Hilley, supposedly died of infectious hepatitis in 1975. He had been ill for some time, but because his symptoms aligned with hepatitis, no tests for poison were carried out. Audrey Marie’s daughter then became ill – eventually her physician suspected heavy metal poisoning. By now, Audrey Marie Hilley was on the run, eluding police for several years during which time she remarried and faked her own death, but the net closed in. Hilley became the model prisoner and was granted a 3 day leave pass – disappearing again.

Concealing the Truth

Larry McNabney was murdered in September, 2001, but his death was so well concealed that no one reported him missing for almost three months. When Larry first met “Elisa Redelsperger”, she already had a long history of credit card fraud and an extensive list of aliases, but within six months of working for Larry in his law firm, they were married. It was no accident that Elisa met Larry – he was a high profile lawyer and she needed to re-invent herself – only this eventually came at the cost of Larry’s life in an unexpected series of macabre events where his body was stored in a refrigerator, before being dragged to a vineyard to rest, for a short while, in a shallow grave.
