Suspect in Iowa Cop Killings Abused His Mother, According to Court Order

— -- The man accused of killing two police officers in Iowa today was found to have abused his mother, with whom he lived, according to an order dated today with the Polk County District Court.

The shootings, described by police as "ambush-style attacks," happened early this morning in central Iowa, when an Urbandale police officer and a Des Moines police officer were fatally shot in their patrol vehicles a few miles away from each other.

Police identified Scott Michael Greene as the suspect. Greene, a 46-year-old Urbandale resident, was captured a few hours after the shootings in Dallas County, where he surrendered to authorities. He has not been charged, police said earlier today.

So far, there were no indications that either of the slain officers had any previous interactions with Greene, according to Des Moines Police Sgt. Paul Parizek.

According to a "Final Elder Abuse Protective Order" dated today with the Polk County District Court, Greene was found to have abused his mother, with whom he lived, "by physically hitting and financially exploiting" her.

He was ordered to move from the home they live in and pay her $10,000.

About two weeks ago, police asked Greene to leave a football game at Urbandale High School because he waved a Confederate flag during the national anthem, causing some spectators to complain, according to Urbandale Police Chief Ross McCarty.

"He said he was invoking his First Amendment rights and we were trampling on them," McCarty told reporters at a press conference this afternoon.

According to McCarty, Greene has been issued trespass warnings at Urbandale High School, where his daughter is a student.

"There has been some issues with the Urbandale school system lately and we have issued trespass warnings to Mr. Greene," McCarty told reporters. "And the school system is in the process of working out what those would be, being also he had a daughter, who is a student in the school. So they were setting the parameters, working through that."

On April 10, 2014, Greene was arrested for interference with official acts. According to court records, he refused police orders to be pat down. "The suspect was known to go armed," court records said. "The suspect had an unknown pouch on his belt that resembled the bottom of a holster." He was reported by cops to be non-compliant, hostile, combative and made movements toward his pockets and he refused to be searched, according to records. He pleaded guilty and was fined $250 as well as surcharge and court cost.
