I'm writing a light comic cozy, so I don't necessarily need deep deep procedural info, but I do like to have an idea of what's realistic. (Hey, if I deviate from reality, I like to do it by choice.)
Here's the scenario:
I have a scene in which two grown women are expected to be home and are not. One is a witness in an attempted murder committed a few hours earlier, the other is the ex-girlfriend of a possible suspect. There is a minor sign of a struggle (a broken dish in the kitchen), but no blood or other obvious sign of anything being wrong.
One of the people who discover that these women are not home is the county sheriff (of a nearby county - the earlier crimes were committed in his county). He is a relative of one of the women.
He discovers evidence that implicates someone else in the previous crime (someone other than the ex-boyfriend). In the rough draft of the scene he calls in to issue an alert on the new suspect when he first discovers that evidence. Since he's worried about his niece, would he call in an alert on her car?
LATER he discovers evidence (a partial video) that there was an abduction, so he calls in again - but in both cases, I am hazy on exactly what he would be calling in, and what he would be doing.
The video gives him an idea of where the badguys are going - so I assume he'd call his own people to head there. But would he stay in the empty apartment until the local police arrive? Or can he follow his gut and run to where he thinks his niece would be? (He has another witness to leave behind for the cops, but I don't know if he can/should trust her.) Also, he is old and experienced and been a sheriff for a long time. It's a low crime territory but I can't imagine that he's a panicker.
