IMPERIAL • An Imperial man has died after fatally shooting his sister and then shooting himself in the head following an argument Sunday afternoon.

Jefferson County Sheriff officials identified the man on Wednesday as Daniel A. Roberts, 47, of Imperial. He died at a hospital.

Police say Roberts shot and killed his sister Debra Hulen, 55, of St. Louis, after an argument Sunday afternoon, then shot himself.

Sheriff's deputies were called out about 3:10 p.m. Sunday to a disturbance in the 5400 block of Old Lemay Ferry Road.

A woman had called the dispatch center and said that her brother was out of control, according the sheriff's department. At that point, the dispatcher lost phone contact. About one minute later the dispatch center received a second call from the same address from another woman — identified as their mother — who said that her son was on the floor bleeding from his head. The mother said that her daughter was also bleeding and that she was outside in the driveway.

Once they arrived, the deputies found Hulen dead in the driveway of the home. Deputies found Roberts with a gunshot wound on the porch of the home.

Their mother, 81, told authorities that her son and daughter had gotten into an argument before the shooting.
