Suspect in Iowa cop deaths was assaulted by mother

The 66-year-old mother of the suspect in the killing of two Iowa police officers was arrested two weeks ago accused of assaulting her son.

A criminal complaint shows Patricia Greene yelled at her son, Scott Michael Greene, to remove his daughter's service dog from her house Oct. 17.

The complaint says Scott Greene was wearing his deceased father's dog tags and that his mother tried to tear them from around his neck. Greene grabbed his mother's hand and she hit and scratched his face.

Scott Greene showed an officer cellphone video of the confrontation.

His mother was released on a $1,000 cash bond and a judge ordered that she have no contact with her son. She is due in court on the charge later this month.

The complaint doesn't say why Greene's daughter has a service dog.
