Diego Hernandez, a 22-year-old Canadian martial arts instructor, was last seen in Puerto Vallarta, Mexico, on May 8, 2013. Since then, Diego’s mother, Melissa Canez, has never stopped searching, and asking questions of Mexican authorities.

On May 8, 2013, Diego Hernandez disappeared without a trace. The disappearances had all the earmarks of an abduction, except for one thing: after nearly six months, there has been no ransom demand.

It's been one year since Diego Hernandez, a 22-year-old Canadian expat who was trying to start a martial arts business, disappeared in Mexico, believed to be a kidnap victim.
