On January 8, 1990, 64-year-old Virginia Denney and her husband Richard were shot and killed inside their Tonkawa, Oklahoma farmhouse. Three individuals — Robert Wesley Knighton, Lawrence Brittain, and Ruth Renee Williams — had approached the Denneys claiming they needed help because their vehicle was low on gas. The group left with about $61 and the Denneys’ pickup truck, actions described as part of a broader crime spree that began after Knighton left a halfway house and included earlier killings in Missouri.

Knighton, Brittain, and Williams were later arrested; Knighton was identified as the shooter. Little is known publicly about what happened inside the house beyond these facts.

Did anyone in or near Tonkawa at the time see the trio’s vehicle or notice anything unusual around the Denney property that day?
