A well-known fake news website named World News Daily Report posted a hoax article titled "STUCK 71 HOURS IN AN ELEVATOR, MAN KILLS AND EATS HIS WIFE TO SURVIVE". The article starts off like this:
Philadephia, PA | 44-year old Bruce Franklin was arrested this morning, after he confessed to killing his wife and eating her flesh while he was stuck with her in an elevator.
According to the Philadelphia Police Department, the partially devoured corpse of his wife was lying next to him when he was rescued after being stuck for three days in an elevator.
The story is accompanied by a weird-looking mugshot:
We weren't able to track down the exact identity of the person in the photo but according to Google Image search the image has been used in several 'crazy mugshot' galleries on the internet, for example this one.
The website World News Daily Report is a well known hoax website specialized in posting hoaxes and made up stories. The disclaimer on their website is pretty clear about that even though you have to scroll all the way down the page to find it:
WNDR assumes however all responsibility for the satirical nature of its articles and for the fictional nature of their content. All characters appearing in the articles in this website - even those based on real people - are entirely fictional and any resemblance between them and any persons, living, dead, or undead is purely a miracle.
It appears the story suddenly got popular a few hours ago as you can see in the Trendolizer graph at the end of this article despite not gaining much traction at first. If you notice anyone spreading the rumor around you can help by pointing them to this article here because nobody likes being fooled by fake news.
