FORT DODGE, Iowa (AP) — A man charged in the killing of his girlfriend’s mother in Fort Dodge earlier this year has pleaded not guilty. The Messenger reports that 29-year-old Mark Russell, of Fort Dodge, pleaded not guilty on Monday to first-degree murder in the January beating death of 45-year-old Angela McLeod. Police were called to McLeod’s home on Jan. 20 for a domestic dispute report and found her gravely injured. She was pronounced dead at the scene. Investigators say in court documents that they believe Russell used a golf club to beat McLeod. Russell was found competent to stand trial in May following treatment for mental illness. Russell’s lawyer says his client has a history of schizophrenia.
