Sorry, I haven´t been around for a while, but it is clear to me that Sheila did the killings. So much led up to it. Her thinking her sons were the Devil and capable of having sex with her, the sudden reduction of her medicine, Haloperidol (look it up), her whole history of violence because of mental illness. Some people think that a lovely young woman couln´t do a thing like that.
I challenge you. Look into her past, look into her history. I can understand that it is easier for Colin Caffell, her ex-huband, to put the blame on Jeremy. But that is to avoid responsibility for leaving his sons with a highly unstable mother. To be cruel, I could say, if Colin had truly cared for his sons, he would never have let them out of his car, ever. A mother wouldn´t have left her children with an unstable father, would she? Turned upside down, would a mother willingly leave her children in the care of a man with a similar history of violence as Sheila had? I know I wouldn´t!
