OMAHA, Neb. (AP) — A Douglas County prosecutor says an Omaha man accused of killing his older brother sliced his throat to make sure he was dead.

Prosecutor David Wear said Wednesday that 23-year-old Stephen Russell used a knife to saw his brother’s neck for a minute. The body of 27-year-old Jonathan Russell was found by his mother Saturday at the family home. He died of multiple stab wounds and from his throat being slit.

Stephen Russell was charged with first-degree murder and use of a deadly weapon to commit a felony after turning himself in to authorities.

A judge has ordered that Stephen Russell be held without bail. Online court records don’t list an attorney to request comment on his behalf.
