Looking For Lost Black Belt?!?!?!

Need some help from the BJJ community. We are trying to locate Rodolfo Amaro Da Silva, Gracie Barra Black belt, last seen enroute to Germany From Brazil. His flight stopped over in Boston, but he was not listed as boarding his connecting flight to Germany. If anyone may have seen or heard from him, please notify brian@groundfighters.com
If anyone else even knows of him, please reply or email as we are trying to figure out, what, may have happened to him on this trip 2 weeks ago. Thanks all,
