In this final, fourth part about the Brabant killers, we leave history for this one podcast episode, and explore the different theories behind these crimes. Mind that this is not a historic overview, but purely speculation to inform the listeners about the less conventional theories that have been put forward.
This is purely given as an addendum to part 2 and 3.

(spoiler alert: I'm doing a small conspiracy-podcast impression here at the start of the episode, don't be alarmed :)
