According to the guilty mob, Jeremy not only tricked Essex police into initially believing that Sheila had shot the others, and then herself, but he also tricked Julie Mugford' into believing that he (Jeremy) had hired a hitman to carry out the killings for £2000...
Mugford' did not come forward voluntarily, she was pressurised to do so, at peril of being drawn into the sordid affair, by her pal who actually contacted the police on Mugford' behalf...
Her half baked account was soon exposed as nothing short of a fairy tale, I think as soon as she realised she wouldn't be getting g her hands on any of the inheritance benefits coming her way, once Jeremy dumped her, she took the path 'hell hath no fury like a woman scorned', and got a £25,000 payday for her troubles!
No hitman shot and killed Sheila Caffell, but the cops did!
