I think that article must be wrong. Even assuming the ambulance arrived at the same time as the cops, which is by no means certain, of course the cops didn't wait for Melinda to be loaded onto a stretcher and taken away before they dealt with anyone else in the house. That just doesn't make any sense. And if they found Melinda and called an ambulance, what were they doing while they waited for the ambulance to arrive? Anyway, one of the first articles mentioned that the police report stated that Steven never asked to see his wife. Why would he ask, if the ambulance had already left, sirens blazing? Maybe one of the LE people on this site can provide some insight, but to me it looks like there was simply some sloppy reporting going on.
