Even if you haven't binge watched all ten hours of Making a Murderer, you're probably at least somewhat familiar with the mysteries surrounding the 2005 killing of Teresa Halbach.
If not, allow us to give you a very brief, Wisconsin-accent-free rundown of the salient facts:
A Manitowoc County, WI man named Steven Avery was falsely convicted of rape in 1985, and served 18 years in prison before being exonerated by DNA evidence.
Avery sued the county for $36 million, but was arrested for the murder of a 25-year-old woman named Teresa Halbach before he was able to see his civil case through.
Now, Avery is serving a life sentence behind bars, and both his lawyers and the wildly popular Netflix documentary series still maintain that he's the victim of an elaborate frame-up executed by vengeful law enforcement officials.
There's ample reason to believe that Avery was framed, or at least convicted by a biased jury, but as with all conspiracy theories, the arguments in his favor have gotten stranger and stranger as the years have passed by.
For example, check out the latest claim from Avery's own mother, who says that her son can't be guilty of murdering Theresa Halbach - because Teresa Halbach is still alive.
To be fair, Avery's mother is elderly, and even if Steven didn't kill Halbach, many people (including Steven) believe that one of her other sons did.
So it's not hard to see why Mrs. Avery would be a proponent of the unlikely theory that Theresa went into hiding just to screw some guy over.
Still, it's an indication of how insane the speculation about this case has gotten.
