A rural Oak Grove man has been charged with fatally beating a Kansas City man last September 2019.

Jackson County prosecutors Thursday charged David Haynie, 28, with second-degree murder and armed criminal action. They allege he beat Darryle Humbird, 53, to death with a rock the morning of Sept. 17 in Humbird’s home in the 9100 block of East 43rd Terrace, in a neighborhood across the street from the Truman Sports Complex.

According to court records, police found a rock at the crime scene with apparent blood on it. Tests revealed Humbird’s DNA, and later Haynie’s, on the rock.

Humbird's daughter told police his credit card had been used multiple times since the crime. Investigators traced those transactions back to Haynie's wife, and two witnesses said Haynie’s wife told them, while apparently intoxicated, that she and her husband had been involved in the beating death in a robbery gone bad.

Police arrested both Haynie and his wife Monday. She said she used Humbird’s credit card but had not been at the crime scene. She said Haynie had drugs and a few thousand dollars of cash that he didn’t have before. Haynie said he had been at Humbird’s home the morning of his death to buy drugs but did not go inside.

Haynie said he didn’t kill Humbird and handle the fatal rock but could not explain how his DNA got on the rock.

Prosecutors requested a cash bond of $200,000.

According to court records, Haynie has pleaded guilty to drug possession, DWI, operating a vehicle without insurance and without a license in cases dating back to 2011.
