Unsolved cases have been the basis for hit documentaries for years now, especially when the case remains cold.
There's a reason why Jack the Ripper is history's most notorious serial killer - to this day, no one knows who terrorized the streets of London in the autumn of 1888. But that hasn't stopped people wondering and guessing time and time again.
And now, we find ourselves stuck at home for the foreseeable future to stop the spread of the coronavirus, we have more time than usual on our hands. So why not put it to good use and try to solve your own cold case?

Simply hop on over to the Unsolved Case Files website, browse the cases on offer, and then decide which one you are going to try and solve (potentially with the input of whoever you're quarantining with).

One of the cases available for solving is Jane Doe's. This is its teaser description:
"On April 23rd, 2001, an unidentified young woman was murdered at an island rehab center for the rich and famous. Her body was found burned beyond recognition in a cabin fire.
"There were only five other people on the island - an addiction counselor and four patients - but police were never able to figure out Jane Doe's identity or who killed her.
"Your job is to figure out who Jane Doe is, how she got to Del Fuego Island, and who killed her. This 2001 cold case remains unsolved."

So? How exactly does it work? I hear you ask. Well, there are three steps to playing the murder mystery game, which we've listed below. They are:
"Read the cold case file with documents, photographs, newspaper clippings and much more.
"Solve 3 objectives to move through the case and get more evidence you need to convict the killer.
"Visit the online answer key to prove you solved the cold case or get hints and keep investigating."

So, if this sounds like the perfect way to spend your time in self-isolation, they are available for purchase on the Unsolved Case Files website for $29.99 each. However, it's worth noting that there may be some limitations to shipping caused by the coronavirus pandemic.
