Man pleads not guilty by reason of insanity in ax murder of 4-year-old nephew

BROOMFIELD, Colo. (KDVR) – Emanuel Joseph Doll, 28, pleaded not guilty by reason of insanity Friday to first-degree murder of his 4-year-old nephew.

Doll is accused of killing his twin sister's son with an ax at their father's Broomfield home on April 27, 2017.

The case is now set for review on July 30. Doll is charged with one count of first-degree murder after deliberation and one count of first-degree murder of a child by a person in a position of trust in the death of his nephew.

The Broomfield Enterprise reports that when police and medics arrived at the scene in 2017, they found a young boy with a “massive amount of trauma” in the basement of the home. The boy's grandparents were babysitting their grandson for half an hour that morning before they found him injured, with an iPad and a bloodied ax laying near his body. The boy was the son of Emanuel Doll's twin sister.
