Okay this first theory is just a random one that barely works with only Epi 2. I was bored and thinking about if Shkannon theory was possible. Be free to rip it apart because it is just a random (maybe it could happen) theory.

Spoiler for George is in Control:

George and Sh/kannon work together with possibly Genji or Gohda.

Together they kill the first six.

Then George and Sh/kannon get into fight about Jessica not being able to accept this.

Sh/kannon goes to Jessica to tell her the truth.

Jessica doesn't accept it and in anger Sh/kannon kills her.

Since Jessica is now dead, Kannon persona has no reason to exist,
and is therefore dead.

Shannon ends up at the back door, possibly with evidence of her killing
Jessica.

She and Genji/Gohda agree to pay off the other servents but Nanjo and
Kumasawa refuse the bribe.

So the three kill them.

Shannon, George, and Gohda meet back up and head to Natsuhi's room
to lure Gohda into pravcy.

George tells Shannon to get rid of all evidence and kills Gohda,
getting rid of his cut of the gold.

George then tricks Shannon and fatally injures her.

Feeling betrayed, Shannon kills George before she dies.

After this point, everything acted as it's own accord
(AKA the explosion)

Okay this theory is more serious.

Spoiler for Kinzo is the Bomb:

According to the red text: Kinzo has been dead before the events. What if the murderer killed him before anyone came to the island and then placed him in the boiler to get rid of the evidence. But the body ended up causing the boiler to block up and cause the explosion at the end.

If this is possible, then Kinzo is the murderer because his dead body caused everything to explode. Lol
