I think there is some evidence for another option: he was a paid hitman doing a job he was paid to do.
The guy has made million on gambling, which suggests he’s been paid millions for illegal work and laundered through the casinos. He also traveled all over the world on mysterious trips.
He had an escape plan, which means this wasn’t about a suicide mission.
He did ballistic calculations on a notebook, which also seems to suggest he’s a professional.
What if he was a professional hitman and this was a paid job.
“He had an escape plan, which means this wasn’t about a suicide mission”
then why shoot himself? so early in the whole event? or why stop his shooting rampage so quickly and be silent for almost an hour before being found dead?
I currently think someone shot him to look like suicide.
I also question why Campo was only shot once in leg if numerous bullets were shot threw door at him?
“Professional hitman?” That makes a lot more sense than small time landlord with cash to burn and certainly more sense than someone consistently beating the house.
