OMAHA, Neb. (AP) — An Omaha man who authorities say stabbed his brother at least 70 times has been given 60 to 70 years in prison.

Twenty-four-year-old Stephen Russell was sentenced Tuesday. He’d pleaded no contest and was convicted of second-degree murder in the slaying of 27-year-old Jonathan Russell in April. Prosecutors had lowered the murder charge and dropped a weapons count in exchange for Stephen Russell’s plea.

Authorities say the body was found by the Russells’ mother inside the family home.

Stephen Russell apologized to his family at his sentencing hearing and said, “What happened on April 4 was a horrible mistake.”
