Update: Suspect now in custody
Law enforcement officials in Iowa say they have captured the top suspect in the killing of two police officers in separate shootings overnight.
The Des Moines Register reports:
Scott Michael Greene is suspected of ambushing two metro-area police officers were shot and killed in apparent "ambush style" attacks early Wednesday.
As of 7:30 a.m., police identified Scott Michael Greene as a suspect in the fatal shootings. By 9:30, he was taken into custody, according to Urbandale police spokesman Sgt. Chad Underwood.
Authorities said Greene surrendered to a Department of Natural Resources officer in Dallas County. There was no struggle. He was in the custody of the Iowa State Patrol Wednesday morning.
Two police officers were found dead in their patrol cars in Des Moines, Iowa, early Wednesday morning after what officials described as "ambush-style" attacks.
Officials have named as a suspect a 46-year-old white male named Scott Michael Greene, from Urbandale, Iowa.
"Greene is believed to be armed and should be considered dangerous. If seen, please do not approach Greene, but call 911 and report his location," Des Moines police said in press statement.
Greene has reportedly been arrested previously for domestic violence and driving under the influence. Online social media profiles belonging to someone who appears to be Greene show him waving a confederate flag in front of African-American spectators at a sporting event and spouting racist rhetoric in online comments.
Des Moines police sergeant Paul Parizek told reporters after the shooting: "In all appearances, it looks like these officers were ambushed. On the surface, it doesn't look like there was any interaction between these officers and whoever the coward was that shot them while they were sat in their cars."
A manhunt for Greene is currently underway.
