Mark Doran Kline, 45, was killed on the evening of July 17, 2026, inside a residence on South 8th Street in Kansas City, Kansas. A 911 disturbance call brought officers to the home, where Kline was found suffering from apparent gunshot wounds and was pronounced dead at the scene. He is described as a father of three and a well-liked member of his community who enjoyed sports and time with family and friends.

A 34-year-old resident of the home, B'anca Monet Guess, was taken into custody at the scene and charged with second-degree murder. Guess was held in the Wyandotte County Jail on $250,000 bond.

Does anyone who knew Mark or who was in that neighborhood the night of July 17 have information that could help the investigation?
