SHORTLY BEFORE DEP IN SMF AN OMC FROM ACR REQUESTED TO JUMP SEAT ON FLT SMF-DEN. THE CAPT IN THE L SEAT WAS BEING GIVEN AN IOE FOR HIS TRANSITION FROM B737-200 TO A B737-300/500 CAPT. I WAS THE CAPT OF RECORD IN THE R SEAT AS A STANDARD'S CAPT FOR ACR. AB ASKED FOR AND RECEIVED A COMPANY IDENT AND AN FAA PLT'S LICENSE FROM THE OMC. ON INSPECTION THESE 2 FORMS OF IDENT APPEARED TO BE VALID AND THE JUMP SEAT WAS OFFERED TO THIS INDIVIDUAL. DURING THE FLT TO DENVER THE OMC EXPLAINED THAT HE WAS ENRTE TO FLL TO ATTEND THE FUNERAL OF HIS BROTHER; WHO HAD BEEN KILLED BY A DRUNK DRIVER. I SENT A MESSAGE TO DISPATCH OVER THE ACARS TO INQUIRE IF WE COULD GIVE THE OMC PRIORITY ON HIS FLT FROM DEN TO FLA. THE RESPONSE FROM DISPATCH THROUGH ACARS WAS FOR THE OMC TO CONTACT THE ORD DUTY MGR ON THE GND IN DEN FOR PRIORITY OMC TO FLL. I PASSED THE PRINTED MESSAGE FROM DISPATCH TO THE OMC; WHO APPEARED AT THE TIME TO BE TOUCHED BY ACR KINDNESS. ON ARR IN DEN; A DEN DOMICILE MGR (YY) MET THE FLT AND ASKED THE OMC IF HE WOULD MIND GOING TO THE FLT OFFICE FOR SOME QUESTIONS. UPON ENTERING THE TERMINAL THE OMC WAS ARRESTED BY THE DENVER POLICE FOR ILLEGALLY RIDING A JUMP SEAT WITHOUT PROPER AUTH. INITIALLY; WE WERE INFORMED THE OMC HAD BEEN FIRED BY ACR 'K' AND WAS USING AN INVALID IDENT. FURTHER INVESTIGATION DETERMINED THE IDENT TO BE FORGED; AND THE OMC HAD NEVER BEEN EMPLOYED BY ACR 'K.' HIS FAA PLT'S LICENSE; HOWEVER; WAS VALID.
