Jennifer Finnigan is calling for a public inquiry into the death of her daughter, Gemma Finnigan.
Daniel Johnson had been out on life licence when he went on to kill Gemma, 24, in the flat they shared in Church View, Boldon Colliery, on September 13, 2013, in a brutal attack.
He was jailed for life after pleading guilty to manslaughter on the grounds of diminished responsibility.

A Domestic Homicide Review revealed a number of missed opportunities when it came to monitoring the 24-year-old’s partner Johnson.
Johnson had met Gemma while on day release from prison, where he had been serving time for his part in killing a man – something the family maintain they were never told the full details of.
The Ministry of Justice claims they were told the full details of his conviction.
Now, her mum along with family friends, have launched a petition calling for a public inquiry into Gemma’s death.
They will meet with Jarrow MP Stephen Hepburn next week to raise their concerns and to see if there is anything he can do to help them.
Miss Finnigan said: “I just want justice for my daughter. Gemma didn’t deserve to die.
“There are just so many questions that still need answering, but it’s like, here’s the report and that’s the end of it.
“Gemma is worth much more than that. Gemma was let down and we need answers.
“I don’t know what will happen when we meet Stephen Hepburn, but we are hoping he will be able to at least offer some advice on what we can do next.”
A spokesman for the Ministry of Justice said: “This was a horrific crime and our thoughts are with the family and friends of the victim.
“Public protection is our priority. A review found this case was managed sufficiently, but also raised areas for improvement that have since been addressed by the Probation Service.
“Serious offences are rare, but each one is taken seriously and fully investigated, with measures put in place where lessons can be learned.”
Mr Hepburn said: “I am of course very much aware of the tragic circumstances surrounding Gemma’s death.
“I will be meeting with Jennifer personally to discuss this matter in more depth.”
