What's the story? Do they think the other six bodies were there when he moved in? I mean, I know a D.A. will only charge the crimes he thinks he can get a conviction for, but it seems like if you can prove the dude killed five people, it shouldn't be hard to convince a jury to tack on the other six corpses you found in his house. Or is it some kind of paperwork thing, where they've only charged him with five murders so far?
Your help would be appreciated in clarifying this matter.
