That doesn't explain the spike in deaths from when she qualified to work in the NNICU.
They took babies like that before she started there, and there were nowhere near the level of deaths that happened after she started there.
And don't forget that the investigation - hundreds of cases - from her previous work.- is ongoing.
The timing of many of the deaths was also incredibly unlikely to make them accidental/negligent. 100 day anniversaries, due date anniversaries, imminent discharges. She predicted collapses and deaths (in unlikely cases) and they happened within hours.
Also those consultants reported, and begged for investigations and action, hardly likely if you knew you were negligent.
She had patient notes in her home she knew shouldn't be there, marked as not to be thrown out, that she took with her through house moves .... Meanwhile she had a shredder and shredded her bank documents.
She noted the deaths in her diaries and stalked the families on anniversaries and significant occasions. Only when they would have been posting things about their bereavements.
The parents reported totally inappropriate and ghoulish behaviour from her on numerous occasions.
The babies who were murdered died consistently by wherever method she'd just been trained on (i.e. trained to avoid/deal with).
I could go on.
