Wednesday, November 2, 2016 Suspect in fatal ambush of two Iowa police officers capturedSuspect Scott Michael Greene, 46, was caught by Urbandale police after two Iowa police officers were shot dead in separate "ambush-style" killings as they sat in their patrol cars. Police in Iowa said on Wednesday they have captured a man suspected of killing two police officers hours earlier as they sat in their patrol cars in what authorities called separate and unprovoked attacks. Scott Michael Greene, who is 46 and white, was taken into custody after police named him as their suspect in the ambushes, a police spokeswoman in Urbandale, Iowa said. Police said they found the first slain officer's body about 1:06 a.m. (0606 GMT) in Urbandale, an affluent Des Moines suburb, and the second about 20 minutes later about two miles (3 km) away, in Des Moines. It was unclear what provoked Wednesday's attacks, Des Moines police department spokesman Paul Parizek told a news conference prior to Greene's arrest, adding that "we may never know."
