Crime supposedly concealed in Royal Caribbean Cruise Ship

Since the murder of Dianne Brimble, there is a big society push to crack down and stop crimes on international cruise ships.
The most tough legislation concertning international cruise ships is the US one.
A group for lobbying for more such laws has been created, called "International Cruise Victims". Bree Smith, the vice-Presiden tof the group announces that countries, in which the group wants to have influence include Australia.
Bree Smith lost her younger brother on one Royal Caribbean ship last year, which makes her so personally involved. George Smith, her brother, chose for his honeymoon a 12-day cruise. On the sixth day of the voyage he went missing. The Royal Caribbean did everything possible to conceal the incident and contaminate the crime scene. As a result, nobody went to jail, the body was not found, too.
Sounds like an Agatha Christy novel, doesn't it?
Unfortunately, it is for real. More people can become victims, can end up like George Smith, so that is why these cases need to gain publicity.
