Allegations against British businessman pilot Hamish Harding's stepson, Brian Szasz, surfaced on the Internet after he was spotted attending a Blink 182 concert to cope with "life's toughest times."

Reportedly, there is only 40 hours of oxygen left.However, on June 19, Szasz took to his Facebook handle to share a picture of himself attending a Blink 182 concert to apparently tackle his emotional stress. According to several media reports, he captioned a since-deleted post:"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!"Screenshot of Brian attending a Blink 182 concert in a since-deleted post.In the picture, Hamish Harding's son can be seen smiling while posing in front of a Blink 182 merchandise tent.
