The stepson of a billionaire on board a missing vessel which had been exploring the Titanic wreckage has posted images of himself enjoying a Blink-182 concert.
The gig in San Diego took place as the search for his stepdad Hamish Harding and four other passengers continued a day after they were reported missing at sea.
Brian Szasz admitted he knew some people would find his appearance at the gig "distasteful" but he tried to justify his actions.
