From another article (I suppose that more can be said now the court case is over)
In a statement after Gibson was convicted of murder this week, former foster father Craig Niven said: “When they arrived at our home – Amber aged three and Connor aged five – Connor stated: ‘We are safe now’. They were until he took her safety away.”
The couple was granted permanent care of the siblings a few years later, yet concerns were soon raised about the children’s behaviour. Giving evidence during the trial, Mr Niven said he would not leave the two alone together as they were “not a good mix”.
When Amber was just 14 years-old, the foster care arrangement broke down and she moved into Hillhouse children’s unit, while her brother remained with the Nivens until his 18th birthday.
It was while she was being looked after by social services that Amber was raped by Jamie Starrs at his home in Bothwell in June 2021. The 20-year-old was on bail at the time for another sex attack and was found guilty of the assault on Amber earlier this month.
Her brother had remained a constant presence in her life. Despite describing their relationship as turbulent, Amber’s friend told jurors she had been looking forward to seeing him in the hours before she was killed.
At the time, he was a resident at Hamilton’s Blue Triangle project, a hostel for homeless youngsters. After Gibson called the Hillhouse unit to speak to his sister, care home manager Ian Currie attempted to discourage her from leaving but his efforts fell on deaf ears.

I just cant understand why she was sent to a children's home and her brother got to stay with the foster family. They must have known she would be more vulnerable in a situation like that.
But as said up thread, whatever happened in their very early years must have been traumatic and appears to have had a lasting effect.
