Mafia 20. Radioactive Dreams.

In my scenarios, logic came first, and everything else followed...

It's not always possible to create a logical and complex clue based on the killer's profile, so sometimes you have to resort to something like this. And I described a possible scenario, if you need a logical explanation. Or better yet, ask Toria how old the machines are that they use here; it's his world, after all, even though it's based on the paintings of some artist (if I'm not mistaken).
