There are plenty of folks in our art who do their fair share of "Kajukenbo Detective" work, and I'm sure they're on the case right now. But IMO, it also helps to find out what someone is teaching. There are plenty of Kaju people with pure lineage who might not be able to teach you what you need.
That said, I don't know the gentleman you referenced. But then there are a lot of people in Kajukenbo and it's no longer possible to know everyone.
I hope you find out what you're looking for.
