On a summer morning in rural southwest Payne County, near Perkins, Oklahoma, the life of Ada Lyn Killough, a 41-year-old White woman, was tragically cut short. On July 14, 2023, she had arrived at a residence to perform house cleaning services, a routine task that would end in a fatal encounter.
Unbeknownst to her, her former boyfriend, 46-year-old Timothy Robinson, was aware of her schedule and lay in wait.
Upon her arrival, Robinson allegedly shot and killed Killough before turning the weapon on himself. The Payne County Sheriff's Office responded to a call of shots fired at approximately 10:16 a.m. and discovered both individuals deceased at the scene.
Preliminary investigations by the authorities pointed towards domestic violence as the motive behind the murder-suicide. It was noted that Killough did not reside at the home where the incident took place. The investigation concluded that Robinson was the primary suspect and with his death, the case was considered solved.
