Her attacker, serial sex offender Leroy Campbell, had been released from prison just four months earlier and told probation staff he may rape again weeks before the murder.
After a watchdog review found a series of failings by the probation service, Lisa’s sister Alison Parker tells Sky News why she believes those who failed to monitor Campbell properly should be held accountable for her death.
My whole family still feel anger and hatred towards Campbell. I believe they should bring back the lethal injection.
Why should the government pay to keep him alive all these years, feeding him and keeping him warm over the winter? Why should the government pick up the bill?
A life’s a life and he knew exactly what he was doing – he raped and killed my sister and tried to kill my mum.
But I’m also angry about the catastrophic failings by the probation service.
Campbell did the crime but what about those people who didn’t do their jobs properly to monitor him?
If they had done their jobs and knew the triggers that set him off, they would have recalled him straight away and he would’ve been taken back in prison. We wouldn’t be in this situation.
The report by the chief inspector of probation says Campbell had told probation staff he was thinking of raping again and had been looking at open windows.
He was supposed to have been supervised in the community but he wasn’t living in approved premises at the time of the attack.
Campbell was a danger to women, so why was he ever let out?
My sister Lisa was a kind and considerate person. She would go to the end of the earth to help anybody.
As a community district nurse, she went above and beyond her duty with her patients, often staying way past the time she should have finished her shifts.
She saw a lot of my mum because they lived close to each other in Wolverhampton.
That’s why my mum was caught up in the horrific crime.
Lisa had been off work sick and my mum called round to see how she was because Lisa lived on her own.
But two hours earlier Campbell had broken into my sister’s flat through her bedroom window and my mum disturbed him when she arrived.
He then strangled and beat my 80-year-old mother.
Campbell then set fire to the house, left the gas cooker on and escaped.
A neighbour saw the flames and dragged my mum out of the house just in time and called the police.
I was with my husband and my children when I got the horrific call saying that something had happened to Lisa and my mum.
I still don’t know how I managed to drive the car to my sister’s house. My heart was going ten to the dozen.
I remember saying: “Where’s my mum? Where’s my sister?”
When I arrived at the house, I saw my sister being taken away in the ambulance. But it was no good.
The police asked us if we recognised the name Leroy Campbell but we didn’t.
It later emerged that Campbell had been planning his attack – CCTV revealed he had been practicing putting a ladder against the wall leading up to Lisa’s bedroom window.
When we found about his past crimes – how horrific they were and how he’d been allowed to return to Wolverhampton where he committed his last crime – it beggared belief.
The police, the probation service and the parole board are partly to blame for Lisa’s death.
Those who failed her must be held accountable.
My mum says the light has gone out in her life and it will never come back.
She hasn’t been the same since and she doesn’t think she’ll ever recover.
She rarely goes out now. She has a phobia of windows being open and she doesn’t like to go first into a room behind a closed door.
In a way we’ve lost a piece of our mum as well as Lisa.
