(CNN) 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 occurred, police said . On Thursday, Greene was arrested and charged with two counts of murder after authorities found enough evidence to buttress the charges, police said. Investigators believe Scott Michael Greene, 46, shot Urbandale police Officer Justin Martin and Des Moines police Sgt. Investigators don't know of a motive in Wednesday's shootings, Parizek said. UPD is saddened to report that an Urbandale Officer was killed in the line of duty overnight.
