The news of the missing submersible that was en route to view the Titanic wreckage took the internet by storm yesterday.

It didn't take long, though, for the stepson of one of the passengers aboard the sub—billionaire Hamish Harding—to make headlines of his own.

In the midst of his stepfather's disappearance, Brian Szasz was called out on social media for attending a Blink-182 concert... and posting about it on Facebook.

He has since deleted his account or made it private, but some of his publicly expressed thoughts were captured, nonetheless.

Szasz did first share BBC's article on the missing vessel, adding:

"My stepdad Hamish Harding is on this Submarine thoughts and prayers."

But the post that caught the attention of many was the one which explained his reasoning for attending the concert:

"It might be distasteful being here but my family would want me to be at the Blink-182 show as it's my favorite band and music helps me in difficult times! 🖤🙏"

Szasz took it a step further and reached out to the band and its members on Twitter.

"@blink182 ⁦@tomdelonge⁩ ⁦@travisbarker⁩ @markhoppis My stepdad Hamish is on this submarine lost at sea. I’m devastated but coming to the San Diego show tonight so you guys can give me hope and cheer me up.🖤🙏"

In another he shared:

"@tomdelonge my stepdad is missing in the sub at the titanic site. I’m here at the San Diego show for support thanks.🖤🙏"

And then:

"@tomdelonge Tom I’m back at the Blink show tonight to comfort me in this time of tragedy in the fam. Thanks for the love!🖤🙏"

Szasz also posted videos from the concert to Twitter and hit on an OnlyFans model before deleting his account.

People on the platform were a bit perplexed.

Many questioned his motive.

Even Cardi B called out the stepson, inciting a bit of an online war.

In her video, the singer responded to Szasz by letting him know that, yes, he should be at home sad instead of at a concert.

Szasz responded through his Instagram stories.

He claimed he had several reasons to justify his concert attendance, including not having money and not being able to legally go to the site. However no one asked for him to go to the site, most called out his repeated messages to Blink 182 using his stepfather's disappearance to get a response.

He also said some unkind things about Cardi B.

Szasz also tweeted at Cardi B.

A few on social media agreed with his position.

But most shared the same sentiment as Cardi B as Szasz appeared to be trying to cash in on his stepfather's accident.

It was reported Thursday afternoon that the submersible Titan suffered a "catastrophic implosion" likely killing all on board almost instantly.
