In my current WIP I have a murder that takes place within the first chapter, and though this isn't a crime/mystery novel, there is going to be a bit of a sub-plot involving a homicide investigation. I've been trying to figure out when I need to be researching how this is done (as in 1st draft, 2nd draft, etc) and also how it needs to be researched. I've done a few google searches just to see what resources are out there online. However, this hasn't turned up anything too impressive. I'm just curious as to how others have tackled this kinda thing.
