The son of one of the victims of the Horden shootings has told ITV News he hopes gun controls will be tightened within months.
Bobby Turnbull's mother, sister and aunt were shot dead in County Durham by Michael Atherton.
At the inquest into their deaths the coroner called for drastic changes to the way guns are licensed, and Bobby travelled to London to try to secure the changes he wants to be made.

The Independent Police Complaints Commission (IPCC) is urging the government to tighten UK gun licensing laws.
It follows an investigation into the fatal shooting of three women in Horden, County Durham, last year.
Michael Atheron killed his partner, Susan McGoldrick, her sister, Alison Turnbull and Alison's daughter Tanya, before shooting himself.
Atherton held a gun license, despite several police call-outs to his house for domestic violence and a suicide threat.
The IPCC says police cautions should be legally declared by anyone applying for a gun license.
Relatives of the murdered women have been campaigning for changes.
Police are appealing for help from the public to trace a missing 82-year-old from the Horden area.
George 'Slogger' Williams is believed to have left his home in Cresswell Avenue at around 11.45am and has not been seen by his family since.
Officers are particularly concerned because George suffers from a number of medical conditions and can become easily confused.
Mr Williams walks with a walking stick and he is described at 5 foot 5 inches tall, of slim build and wearing a green jacket, blue polo shirt and trousers and black shoes.
Anyone with information is being asked to call Peterlee police on 101.
The family of the Horden shootings victims say the Queen's speech has been an opportunity missed. They are disappointed that plans to change the guns laws haven't been made a priority.
Back in March an inquest into the deaths was held with the coroner concluding an urgent review was necessary.
Watch Frances Read's report:
A man whose mother, sister and aunt were killed by a gunman is lobbying MPs for tighter laws around gun ownership.
Bobby Turnbull met with the shadow home secretary Yvette Cooper at Westminster to talk about his campaign for more gun control.
A man who had three relatives killed by a County Durham gunman who then killed himself is taking his fight to change the law to the Houses of Parliament.
Bobby Turnbull wants to tighten gun legislation after losing his mother Alison, sister Tanya, and aunt Susan, on New Year's Day last year.
They were shot by 42-year-old Michael Atherton at his home in Horden, near Peterlee, who legally owned firearms despite a history of domestic violence.
Bobby has already won the backing of shadow home secretary Yvette Cooper after meeting with her earlier this month.
Next week he will meet with Damian Green, the Minister for Policing and Criminal Justice, where he will continue to lobby for tougher rules on gun licensing.
Atherton had his guns removed by police in 2008 after he threatened while drunk to blow his own head off, but the guns were later returned.
A crash in County Durham has been referred to the police watchdog, the Independent Police Complaints Commission, after a man died just minutes after police spotted his car driving at speed.

They then discovered moments later that the car had crashed near Horden.
The driver, 22-year-old Glenn Robinson from Shotton Colliery, died at the scene.
Durham Police are appealing for witnesses to come forward with any information after a 22-year-old man died after a fatal collision.
Glenn Robinson died after his car left the road in Horden on Sunday evening.
“This was a tragic death of a young man who was returning home from a night out with a friend.
We are still working to establish why the car left the road.
We know that an officer in an unmarked police car had seen the car beingdriven at speed along Essington Way and turned to follow it with the aim of getting it to stop.
However, our enquiries have shown that there was no police pursuit in progress and at no time did Glenn fail to stop for the police.”
Any witnesses should ring Durham police on 101 and ask for the roads policing unit.
