On the evening of August 7, 2016, Douglas Keith Henn, 59, was killed inside his home on Lake Hollow Court in Douglasville, Georgia. The fatal violence followed a family dispute with his 25-year-old step-grandson, Patrick Canada, who lived in the house with Henn and his grandmother, Pamela Lynn Henn.

Canada then went to the basement, retrieved an AK-47, and after Henn locked him in the basement and called 911, Canada broke out and shot Henn multiple times, including a final shot to the head. Pamela Henn was also shot; she was found hiding in a closet, dragged by her hair, and pushed down stairs before escaping the home.

A responding officer, Thomas Lee Altman, exchanged gunfire with Canada in the foyer. Canada was taken into custody at the scene. What details about motive or any additional witnesses are still unknown to the public. Does anyone have information about Douglas Henn or the household that could help clarify what led to this attack?
