I bet they guy was murdered and they just made it look like a Self Delete.
It in NO way looks like a Self Delete, that's why it's so ridiculous that they call it a Self Delete. However, I believe it was a Self Delete. Think about it. If you wanted to go out in an extravagant way, what better way would there be than to look like someone murdered you? I mean, you can blow up your house but then you'll look like a total richardwad and nobody wants that. So think, how do I make it look like a Self Delete? Stand on a ledge with your feet in a sack, pull the sack up over your head, tighten it just enough so your hand can fit out with the gun in it, and shoot yourself in the head. The fall will cause you and the gun to both fall into the water-- the gun will sink, making it unrecoverable, but you will float and be found. To anyone looking, you're a dead carcass in a sack. Total murder. Like, obvious murder. No traceable weapon found, nothing. Bam, your death triggers a murder investigation.
