A Madness Shared by Two, is not only the true untold story about the lives of Sabina and Ursula Eriksson, alongside the murder of Glenn Hollinshead, based on a critique re-examination of the BBC’s Madness in the Fast Lane documentary that had 7 million viewers [with a conservative estimate of around a further 15 million people having since watched this film via the internet and on websites such as YouTube],glued to their TV screens watching the twin sisters propelling themselves into the fast lane of the oncoming traffic on the UK’s-M6 motorway, as Ursula manages to throw herself under the wheels of a 40ft articulated lorry travelling at 60mph, that seems to swallow her up and spit her lifeless looking body back out of its rear end. It is also the result of a thorough investigation into what might have really happened on those fateful days that led up to this tragic slaying of an innocent man. We challenge the “Official Storyline” and expose a 'cover-up' and what really occurred just hours before M6 dash, for it is here for the first time we expose the Eriksson sisters were “arrested” under the Mental Health Act, though this vital caught on film evidence was edited out of the original BBC films. This will come as a great surprise to many people who questioned; ‘...how was it possible Sabina could have been released from hospital after only five hours’ following their ‘suicide attempt’ on the M6? We also reveal that the coroner’s report shows that the injuries inflicted on Glenn, was done so by ‘two’ weapons, it’s always been believed “Sabina” used one, and that it’s highly likely there were more than one person who killed him and that Sabina could be totally innocent. Yet this obvious evidence seems to have been brushed under the carpet, or at the very least, it was never challenged. We explain how these twins were very likely embroiled in some kind of major drugs smuggling ring and that they had been under “Obbo” [police observation] prior to the M6 incident and was probably so for quite some period of time. As a result of our findings, legal action is now being sought and brought against the police and other related authoritative bodies by the Hollinshead family.
