The Daily Mail publishes a photo claiming to depict the Loch Ness Monster. The photo was sold to the paper by a London doctor named R. Kenneth Wilson but evidence of a hoax later emerged. In the 1990s, it came out that two stepbrothers named Ian Wetherell and Christian Spurling may have perpetrated the hoax alongside Wilson because Wetherell’s father had been fired by the Daily Mail while investigating the Loch Ness Monster in 1933.
