On the night of Friday, July 25, 1975, 83-year-old Emma Foster and her 95-year-old husband Jonah Foster were found dead in the kitchen of their Wichita home at 1643 N. Volutia. Their son Quincy Foster raised the alarm after his sister couldn’t reach their parents by telephone; Quincy went to the house, could not get inside, and a patrol officer made the discovery.

Both victims suffered multiple stab wounds. Jonah had two chest wounds, either of which would have been fatal; Emma had thirteen stab wounds to her chest and abdomen. A butcher knife belonging to the Fosters was found in Emma’s hand, but police considered that a staged detail and believed the killer used a different knife, probably with a six-inch blade that was never recovered. The coroner ruled out murder-suicide; time of death was estimated between 7 and 9 p.m. on Thursday, July 24. Neighbors reported seeing Jonah on his porch around 7:20 p.m., and no one reported hearing anything unusual despite the close neighborhood.

No motive has been established and no arrests have been announced. If anyone knew the Fosters, their routines, or saw anything in the neighborhood that Thursday evening, please share what is known.
