Here's a thought for you: the type of explosive in the Horton bomb/fire is very hard to cook if not under an industrial grade exhaust hood; was the perp cooking up his explosives after hours at Hortons?
The story is: he entered the bathroom and soon after it exploded. Whatever he used, he had with him when he got there.

Hmmm... food for thought- some of the restrooms we have in the states have exhaust systems that sound like they are sucking up half the air in the world- he might have thought that would minimize the chances of the smell giving him away.
