This poor girl has been very lucky.
I know of an incident about 35 years ago, also in the UK. A sister was attacked by the mentally unstable son of a couple in the congregation. I don't believe the attacker was baptised but he did attend the meetings and hence was not unknown to the sister. She suffered stab wounds and was rushed to hospital. She was still alive and the doctors wanted to give her a blood transfusion. She died a little later.
At the trial of her killer the defense brought the issue up that had the young girl accepted a blood transfusion she probably would have lived and the charge of murder should be reduced to manslaughter. I am not too sure of the exact out come of the trail but I do know that her killer is still in a secure mental institution and is still considered to be such a risk to the public that he will never be freed.
