Officials have released the cause of death for an Oklahoma City couple killed and dumped in rural eastern Oklahoma.

The Oklahoma Medical Examiner's Office reports the probable cause of death for Virgil, 81, and Rowena, 84, Ingraham both died of strangulation. Rowena's report shows she also died from "blunt force trauma of chest".

The Ingraham's bodies were discovered in November 2017 in a culvert off of I-40 near Tiger Mountain in McIntosh County. The couple had recently been reported missing from their Oklahoma City home. On Jan. 30, an arrest warrant was filed for the Ingraham's grandson, 45-year-old Harlon Lee Foss.

Authorities searched the Ingraham's home and discovered a blood trail leading from the home to the garage. Blood-stained clothes, believed to belong to Foss, were discovered in a washing machine at the home.

The Oklahoma Medical Examiner's Office positively identified the bodies as the Ingraham's on Nov. 28. That same day, their vehicle was found abandoned at an Oklahoma City apartment complex. Authorities spoke with co-workers of Foss at a Moore business. The employees stated that Foss was looking for a new place to live and that his grandparents didn't allow him any freedom and that he "got blamed for everything that went wrong in the house".

Foss was last seen in January near the Aquatic Park of San Francisco, according to SF News. He is described as 5-feet, 9-inches tall and weighing around 230 pounds. He has brown hair and hazel eyes. Anyone with information is asked to call 911.
