Steven Avery and Brendan Dassey's convictions for murder formed the basis of the popular 2015 Netflix documentary series Making a Murderer - but where are they now? The two US men - Avery and his nephew Dassey - were found guilty of the 2005 rape and murder of Teresa Halbach, a 25-year-old photographer, in 2007. Their cases became notorious thanks to Making a Murderer, which left some viewers convinced they had been framed.
