In a quiet, remote country home near Granite, Oklahoma, the lives of two people were tragically cut short on a Sunday evening in January. Forty-year-old Ryan David Nalley and 42-year-old Christine Danielle Kirtley were found deceased inside a residence near East County Road 1350 and State Highway 6. The discovery was made after deputies from the Greer County Sheriff's Office responded to a 911 call from the location. Upon their arrival shortly after 10:00 p.m.
on January 19, 2025, they found a distressing scene.
The deputies discovered that the door to the home appeared to have been broken into. Inside, they found both Nalley and Kirtley with injuries that were consistent with a homicide. Emergency medical services were called to the scene and confirmed both individuals were deceased. The initial investigation pointed towards foul play, prompting the local authorities to request the assistance of the Oklahoma State Bureau of Investigation to lead the inquiry into the double homicide.
As the investigation unfolded, details about Ryan David Nalley's life emerged. Born on October 3, 1984, in Cheyenne, Oklahoma, he was a graduate of Cheyenne Public Schools and later earned a Bachelor's in Business from Southwestern Oklahoma State University. He had three children and was remembered by friends and family for his quick wit and ornery personality. He had a passion for classic country music, was an avid Dallas Cowboys fan, and a knowledgeable gun collector. The news of his violent death sent shockwaves through the community, where both he and Kirtley were described as long-time residents of Western Oklahoma who were well-regarded by those who knew them.
The OSBI, in collaboration with several other law enforcement agencies, worked diligently to identify a suspect. An early lead involving Kirtley's estranged spouse was quickly dismissed as he had a solid alibi. The investigation eventually pointed to 44-year-old Dennis Wade Campbell. However, before an arrest could be made, Campbell was found deceased. Authorities later confirmed that the suspect in the double homicide had been located and was dead, and that there was no further threat to the public. Reports from multiple sources indicated that Campbell had died by suicide. The motive for the tragic events has not been publicly detailed.
