“Two police officers were shot and killed while sitting in their patrol cars in the Des Moines area early Wednesday, in what the police called ‘ambush-style attacks.’
‘We’re just a few hours into this,’ Sgt. Paul Parizek, a spokesman for the Des Moines Police Department, said at a news conference. ‘It doesn’t look like there was any interaction between these officers and whoever the coward is who shot them while they sat in their cars.’”
