On Wednesday morning, a 46-year-old man was arrested for the “ambush-style” shootings that resulted in the death of two Iowa police officers in a Des Moines suburb. 

Police identified the attacker as Scott Michael Greene, who was arrested in Dallas County, Iowa, around 9:30 a.m. The officers were shot as they sat in their patrol vehicles around 1 a.m.  

“These guys were gunned down sitting in their cars doing nothing wrong,” Des Moines Police Sgt. Paul Parizek said about the officers in a press conference.

Before the shooting, Greene had prior altercations with Urbandale police officers. In mid-October, Greene was allegedly removed from a football game at Urbandale High School after taunting Black attendants in the stands with a Confederate flag.

Greene posted a video to YouTube documenting his encounter with the police. In the video, titled “Police Abuse, Civil Rights Violation at Urbandale High School 10/14/16,” a man identified on the site as Scott Greene spoke to Des Moines and Urbandale police officers after being forced to leave the stadium.

The officers are heard telling Greene to leave for “committing a disturbance in the stands.”

“I’m a citizen of the United States of America and I would like my property back that was stolen from me,” Greene said in the video. “I want to report the theft of property from myself. I was actually assaulted. I would like to report an assault.”

Greene alleged that people in the stands assaulted him and took his flag. However, officers informed him that bringing a Confederate flag to a football game is a violation of the school code.

Additionally, The Des Moines Register confirmed that Greene was involved in combative encounters with police in 2014.

In April of 2014, he was charged with a misdemeanor for resisting after an officer suspected he had a weapon and tried to perform a body search. Two days after Greene’s encounter with Officer Chris Greenfield, he was involved in an assault at his apartment complex.

During the assault, Greene approached a Black man in the parking lot of the complex, called him the N-word and said, “I will kill you.” Greene pleaded guilty to a harassment charge and was sentenced to one year of probation.

Des Moines police have named Greene as the sole suspect in the Wednesday morning shootings. The deceased officers have not yet been identified.
