void CG_Obituary_Hook(entityState_t* es, eventParam_t ep)
{
    if( es->attacker == CGS->CG->localClient )
    {
          switch( ep )
          {
             case ep::headshot:
                  CL_AddReliableCommand( "say [ %s ] got killed by a headshot.", client[ es->clientNumber ]->name );
             // ...
          }
    }
}
