Mr. Adam Snipes from Kentucky has no rank in our current Casarez Manabi-Masho Ju-Jitsu System under inheritor Soke Mark Murdock and inheritor Grandmaster Allen Wilson.

We do not recognize Mr. Snipes as any rank in our Casarez Manabi-Masho Ju-Jitsu system. Inheritors Soke Mark Murdock, Grandmaster Allen Wilson and the Casarez Manabi-Masho Ju-Jitsu System/Federation does not or will not recognize Mr. Snipes's 10th Dan as a Manabi-Masho Ju-Jitsu black belt or a 10th Dan in any other art. Any 10th Dan rank given by Professor Casarez was solely awarded by Professor Casarez himself after he retired from the old system and was not given by or recognized by Soke Murdock or Grandmaster Wilson of the new system. Professor Casarez retired 5 years ago and passed the Manabi-Masho Ju-Jitsu System to his inheritors Soke Murdock and Grandmaster Wilson on January 1, 2018 and the system renamed "Casarez Manabi-Masho Ju-Jitsu" after if was passed to the both of them. Soke Murdock and Grandmaster Wilson were not consulted and did not know of any 10th Dan rank advancement that Mr. Snipes received from Professor Casarez. Students with ranks in the old Manabi-Masho Ju-Jitsu system under Professor Casarez, Soke Murdock or Grandmaster Allen Wilson must be grandfathered into or tested into the Casarez Manabi-Masho Ju-Jitsu system under Soke Murdock. We reserve the right to grandfather, test for, or deny anyone rank in our system for any reason we deem fit. We apologize for any statements made earlier that were incorrect because of third party inadequate information.
