Psychiatrists consulted by the defence all said Sheila was not capable of such a murderous rampage.
People said Sheila looked happy on her last day.
We only have Jeremys word (again) that they discussed fostering that night.
But you are only speaking of those consulted. Look at those who review the arts, Who is right and who is wrong. Peoples opinions differ.
People SAID "Sheila looked happy on her last day" but scant hours before she'd attacked a man in such a way he stayed in his car., and again, when she spoke ro her aunt, she sounded withdrawn. I suspect, given she'd just been rejected by her ex husband, was "trapped" -read Fergusons psych report- in a place she hated being- that the latter was closer to the truth. With someone whose temperament was as mercurial as Sheila's, I imagine it would have been difficult to tell from one moment to the next HOW she would be.
