Clifton Achterberg, 34, was killed on June 11, 2018, at his family home on 11th Street near Katyland Drive in Katy, Texas. During a heated dispute with his 62-year-old mother, Gail Achterberg, Clifton allegedly threatened her with a small sledgehammer. Their 31-year-old brother, Walter Achterberg, who witnessed the altercation, fired a pistol, shooting Clifton in the back; the bullet exited Clifton’s chest and struck their mother in the arm. Clifton was pronounced dead at the scene; Gail Achterberg was treated at a hospital and later released.

Walter Achterberg was questioned by police and released after the district attorney declined to file charges. The matter was referred to a grand jury to consider whether any charges should be brought. The family had been involved in recurring disturbances known to the Katy Police Department for years.

Does anyone have information about the events at the home that night or about the family’s history of disturbances that could help clarify what happened?
