as many of you know, my father owns one of the most prestegious martial arts studios in California, and at one time voted as the best in the San Francisco Bay Area. Others of you know the long story behind my father and his ex-teacher, Bob Maschmeier. To make a long story short, Bob (I refuse to call him by his official title, which is something he hasn't earned in my eyes) started coming on to the female students in my dad's dojo and my dad didn't like it. Things got hot and each man went their ways after Bob cut my dad from the Kajukenbo Family Tree. After a few years, it kinda seemed like the Lord was taking revenge on this evil man (I say evil because of what he did to his teacher, who was a godly man who founded a Baptist church in my neighborhood. He was on his deathbed not longer than 2 or 3 years ago, and Bob physically forced him in that time to sign documents for him when he could hardly breathe); one of his students (who was actually one of my dad's students who defected to Bob) caught testicular cancer in... well... both, and Bob caught terminal throat cancer.
Now, you'd think that a man who's dying of cancer would at least stop being quite so evil. Well, that didn't happen. Today, he sent his mafia goonsquad to break into my dad's dojo, do serious damage to it, and steal one thing: my dad's official certificates. Those are irreplacable, and by now, they've probably been burned or otherwise destroyed. Without these, my dad's lost his rank. He can no longer say that he's a certified second degree blackbelt. Bob has dishonored my father, his dojo, his students, and the entire world of organized Martial Arts.
Right now, my father's sitting in his den trying to see if there's anything he can do to salvage anything from the ruins of this disaster. We are angry and don't know what to do.
I have to agree with Kkun, it seems it'd be a good idea to go to the authorities first and foremost. This probably isn't something anyone should try to handle on their own.
I am so so so sorry 
It makes me wonder why people do things like that. Is it that they're jealouse or just plain stupid. It reminds me Rurouni Kenshin alittle bit. Have u guys gone to tha cops yet? They should be able to do something. There should be a copy of your dad's certificate wher he became a black belt. Maybe if he goes back to where he got it they might have records and stuff like that. Good luck with everything
