The question I have is, what is the relationship of the victim to BG? This can go a million different ways. What's the point of murdering someone? Is there a payday? Are you related? Is the BG getting revenge? Is BG a serial killer? There are some very very BG's in this world that appear to be GG's. I'm always interested in the hero who is a very very BG. That makes a plot interesting to me.
Besides, it's easy to make a murder look like a suicide, happens all the time. I will always wonder about Anthony Bourdain and many others that they write off as suicide.
