Des Moines IA Nov 2 2016 A suspect in Wednesday morning's apparent ambush killings of two Iowa police officers was taken into custody hours later, after he flagged down a natural resources officer a county away from where the killings happened, police said.
Investigators believe Scott Michael Greene, 46, shot Urbandale police Officer Justin Martin and Des Moines police Sgt. Anthony "Tony" Beminio while they sat in squad vehicles at intersections roughly 2 miles apart shortly after 1 a.m., authorities said.
Greene, of Urbandale, was taken into custody later that morning after he flagged down a state Department of Natural Resources officer while walking on a gravel road in Dallas County and asked him to call 911, police said.
Greene was not charged in the killings as of noon, but he is "suspected of doing this," Des Moines police Sgt. Paul Parizek said, citing unspecified tips and leads.
Urbandale police said they had interacted with Greene before, including about two weeks ago, when they told him to leave a high school football game.
But Parizek said there was nothing to immediately indicate that either Martin or Beminio had any previous contact with him.
Nor did it appear the officers had much warning that someone was about to shoot them, Parizek said.
"On the surface right now ... it doesn't look like there was any interaction between these officers and whoever the coward is that shot them while they sat in their cars," Parizek said, holding back tears, before Greene was named a suspect.
Greene was taken to a hospital after complaining of an issue with an existing medical condition, and detectives are expected to interrogate him soon, Parizek said.
'These guys were gunned down ... doing nothing wrong'
Police discovered Martin's body around 1:05 a.m., after nearby residents reported shots being fired. Martin's body was seated in his squad car, at an Urbandale intersection just northwest of Des Moines, Parizek said.
Twenty minutes later, as officers responded to the Urbandale shooting, Beminio was found shot in his squad vehicle, at an intersection in Des Moines.
Beminio later died at a hospital, Parizek said. He said both officers were on patrol. Neither was responding to a service call, and neither had radioed about a confrontation.
"In all appearances it looks ... that these officers were ambushed," Parizek said.
"These guys were gunned down sitting in their car, doing nothing wrong."
Investigators believe "over 15 and under 30" shots were fired at Martin alone, Urbandale Police Chief Ross McCarty said.
Urbandale police had asked Greene to leave a high school football game about two weeks ago, prompting him to complain that police were infringing on his rights, McCarty told reporters Wednesday morning.
Greene was asked to leave after he waved a Confederate flag in front of "people of color" during the national anthem, and other people complained it was offensive, McCarty said.
"He said he was invoking his First Amendment rights, and we were trampling on them," McCarty said.
Greene left school property but used public sidewalks to "continue his demonstration," McCarty said.
Police warned Greene to "cease and desist," and he afterward was negotiating with the school about when he'd be permitted at the school, which his daughter attends, the chief said.
Greene is white, as were Martin and Beminio, police said.
Investigators don't know of a motive in Wednesday's shootings, Parizek said.
As news of Wednesday's shootings spread, a woman gave bottled water and other supplies to an Urbandale police officer who was standing along a street, and tearfully gave him a hug, video from CNN affiliate KCCI showed.
"I want you to go home to your families, because I want my dad to come home to me and I want my friends to come home to me, and I'm sorry," she said.
Parizek, the Des Moines police spokesman, choked up as he spoke of Beminio, an 11-year veteran of the force who once worked under Parizek's patrol.
Beminio, married with children, had been a school resource officer and a robbery homicide detective, and was recently promoted.
"A great friend to a lot of us," Parizek said.
Martin, 24, had just finished academy and field training this year, McCarty said.
"We had high expectations (for) his future, and it's tragic it's been cut short," the chief said.
