There are two distinct cases involving the name "Jessica" related to death found in recent sources:
- Jessica Anna Michalik (Australia, 1985-2001) died as a result of asphyxiation after being crushed in a mosh pit during the 2001 Big Day Out music festival at a Limp Bizkit concert. The incident occurred when the crowd surged violently, leading to her fatal injuries. Medical personnel and security cut the performance short, and the case criticized poor crowd control and the band’s handling of the situation. This event is real and well documented.
- Jessica Radcliffe is a name linked to a viral hoax about a marine trainer supposedly killed by an orca attack during a show. The videos claiming this incident are entirely fabricated using AI, and there is no credible evidence that Jessica Radcliffe exists or that such an attack occurred. The viral video is a digital forgery inspired by real orca-related trainer deaths but these are unrelated to any person named Jessica Radcliffe.
Therefore, if the query refers to how "Jessica" died related to the mosh pit incident, it was due to asphyxiation in a crowd crush at a music festival. If it refers to the viral orca trainer story, that is a hoax and the person does not exist. If clarification is needed on a specific Jessica, please specify.
