Police say a man killed his ex-girlfriend's mother at an Iowa home about an hour after officers went to the apartment following a reported assault but left without making an arrest or removing anyone from the tense scene.

Mark Russell, of Fort Dodge, is accused of using a
golf club to beat 45-year-old Angela McLeod to death.
Russell, 28, is scheduled to appear in court Jan. 31 on a first-degree murder charge.
