What happened to "Jessica Dolphin" is actually a case of misinformation and a viral hoax. A video circulating widely on social media claimed to show a marine trainer named Jessica Radcliffe being attacked and killed by an orca (killer whale) or dolphin during a live performance at a supposed "Pacific Blue Marine Park." However:

• There is no evidence that Jessica Radcliffe exists.
• The marine park named in the video does not exist.
• The viral footage is completely fabricated and appears to be AI-generated, including artificial water movements, voices, and crowd reactions.
• Multiple investigations and fact-checking reports confirm that this incident never took place.
• The story is a confusion or revival of a different real dolphin trainer accident that actually happened in 2010, but under a different name and circumstances.

In summary, Jessica Dolphin or Jessica Radcliffe is not a real person, and the alleged attack and death are fictional, created and spread with the help of AI-generated video content to mislead viewers.
