The Iowa Court of Appeals has upheld the murder conviction against a man who went on a jealous rampage at a southwest Iowa bowling alley in February of 2005. Dennis Eugene Stonerook was convicted of murdering his estranged wife’s boyfriend at the Glenwood Bowling Alley.
Witnesses say Stonerook used a semiautomatic rifle to shoot Donald Mayberry. Stonerook’s estranged wife and two children had recently moved into Mayberry’s house. Tests revealed that just after the shooting, Stonerook had a blood-alcohol level that was twice the legal limit.
Stonebrook pleaded insanity and intoxication at his trial. Stonerook was convicted of first degree murder and sentenced to life in prison, but he filed an appeal complaining about the way his attorney handled the jury instructions at his trial. The Court of Appeals has ruled that while the jury instructions could have been written differently, they were “accurate” and no legal error was committed.
