Magnificent effort has been made to show that Sheila's Schizophrenia resulted in her violently killing her children and her parents. But Sheila didn't become Schizophrenic the day she was diagnosed. She would have been so long before that occurred. Much HAS been made of her, alleged, violence, listing alleged violence directed at the twins, violence, one one occasion when she slapped his face, directed at Colin, violence directed at herself, when she was in the grip of psychosis. None of which suggests, to me, a potentially violent person.
Several years ago, I was asked to contribute to a paper being written on a possible link between adopted children and Schizophrenia. Two of the subjects, both male, had shown violent tendencies long before diagnosis. In both cases the violence had been directed towards their mothers, both, at one point, involving knives. Both were diagnosed and medicated, both, as is not unusual with Schizophrenics, stopped taking their medication, both reverted to the previous violent behaviour towards their mothers. One of the mothers required some sort of protection whenever she visited her son. NONE of these behaviours describe Sheila, either prior to diagnosis, or after, but it occurs to me that she may have been justified in feeling violent towards June. It has been claimed that she was quick tempered. "Quick" tempers don't signify violent tempers. NO one, save those who wish to lay the tragedy at her feet, have ever made claims of her violence. Okay, Freddy "feared for my life"! Did she touch him? NO. She hit herself with her hairbrush! That action, and many years prior, putting her OWN hand through a window, appear to be the sum of her violence whilst being unmedicated.
Anti psychotic medication subdues. Sheila was medicated by injection. No chance of her forgetting to take it. It would be strange, indeed, if being medicated caused her, and possibly other Schizophrenics?, to BECOME murderously violent -or even slightly so- when they hadn't previously shown any indication of being such.
