“Their premature departure has left behind an irreparable hole in both our families and the local community; their kind and devoted selves will never be forgotten.”

Tributes have also been paid to 51-year-old Paul Mullen, of Washington, who also lost his life during the incident.

All families are being supported by specially trained officers.

October 19

The lorry driver involved in a fatal motorway crash which killed three people is charged with causing death by dangerous driving.

The Crown Prosecution Service authorised Durham Constabulary to bring charges against a 41-year-old man involved in the collision.

Ion Nicu Onut was charged with three counts of causing death by dangerous driving.

He was remanded on police bail.

A CPS North East Spokesperson said: “The Crown Prosecution Service has authorised Durham Constabulary to charge a man in relation to a fatal road traffic accident which occurred on Thursday July 15 on the A1(M) northbound carriageway, near junction 61.

“The Crown Prosecution Service reminds all concerned that criminal proceedings against Mr Onut are now active and that he has a right to a fair trial.

“It is extremely important that there should be no reporting, commentary or sharing of information online which could in any way prejudice these proceedings.”

January 11

Ion Nicu Onut, 41, was jailed for almost nine years for causing the crash.

He was driving a Scania lorry carrying fertiliser when he lost control on the A1. Durham Crown Court heard he had been looking at sex dating websites at the time of the crash and did not see the stationary traffic ahead.

Onut of Galashiels, Scotland, admitted three counts of causing death by dangerous driving at an earlier court hearing in December.

udge James Adkin jailed him for eight years and ten months.

The judge said: “You were preoccupied with forming casual sexual relationships with strangers while driving down the motorway at 50mph.

“You failed to see the traffic. The consequences were catastrophic.

“The lives of those close to those who died will forever be blighted by their untimely demise.”

The judge said he will serve half of his sentence in prison and the rest on licence, meaning he will be free in four years and five months.

Onut will also be banned from diving for a total of ten years when he is released.

Dashcam footage collected as part of the official investigation showing the lorry driving up the central reservation with a burning vehicle stuck beneath the cab was relased by police to highlight the perils of dangerous driving.
