Tracie Andrews stabbed her fiance Lee Harvey to death on a country lane in December 1996.
She then weaved a web of lies claiming he was the victim of a road rage incident.
But a police press conference would be her undoing and she was eventually convicted and jailed for the murder.
ITV documentary The Road Rage Killer: True Crime Presents, which airs on Friday 18 July from 9pm, explores a case which shocked a nation.
We take a look at the woman at the heart of the crime and what has happened to her in the intervening decades.

Who is Tracie Andrews and what did she do?
Born in April 1969, Tracie Andrews (birth name Tracey Marguerite Andrews) was the middle of three siblings, who grew up in a volatile household.
Her parents separated when she was six years old, which is understood to have made a lasting impression on her.
An aspiring model, she found work locally in her home county of Worcestershire as a barmaid.
By the age of 21, she had given birth to a daughter Karla. She separated from the father a year later.
Then in October 1994, she began a relationship with local bus driver Lee Harvey. Three months later they were living together. They became engaged and were due to marry in the summer of 1997.
It was another volatile relationship, about which friends and family on both sides had concerns. There were a string of violent incidents including one where Andrews hit Mr Harvey over the head with a bottle, another where she bit him on the neck.
Police were called to their home in late October 1996 after a row escalated in to violence.
Just over a month later on Sunday 1 December 1996, the couple were embroiled in another fierce argument at home and had gone to a pub in Bromsgrove to reconcile.
On the car journey back to their flat in The Becks, Alvechurch, Worcestershire, the couple had argued again and they had stopped in a country lane.
Andrews told police they had been pursued in Mr Harvey’s white Ford Escort along country lanes by a blue Ford Sierra after overtaking it. When they pulled over there was an altercation between Mr Harvey, 25, and the driver of the Ford Sierra and he had attacked them both.
But in reality, then 27-year-old Andrews had launched the attack on Mr Harvey with a Swiss Army penknife, stabbing him 42 times in the back, throat and chest.
He suffered a fatal wound to a carotid artery in his neck and died on the country lane.

How did Tracie Andrews’ lie fall apart?
When a resident nearby had heard the commotion outside, he had gone out to find Mr Harvey on the road and Andrews next to him and had called emergency services.
Andrews then told police, Mr Harvey had been stabbed in the road rage incident and she had also been attacked.
At a press conference appealing for witnesses two days later, a tearful Andrews said: “They overtook us and pulled in and Lee got out of the car.
“There was some sort of argument going in.
“The passenger called me a slut and punched me in the face.
“Afterwards I went to Lee, I don’t know whether he was alive.
“I held him, I cradled his head and was just thinking of anything I could do for him.”
She attempted suicide after the press conference and was admitted to hospital.
But her web of lies eventually ensnared her.
A few days later, Andrews was arrested in connection with Mr Harvey’s murder.
She had appeared to contradict her original statement, during the press conference, on timings.
She also switched to claiming the passenger of the Ford Sierra had attacked her and Mr Harvey and not the driver.
A child witness in a nearby cottage said they had heard a man and woman arguing.
Police could find no evidence of a second vehicle chasing Mr Harvey’s white car and none of a second vehicle parked in the lane where the alleged altercation took place.
Instead, witnesses said they had only seen Mr Harvey’s Ford Escort driving past them on the lane that night.
And eventually police found a penknife-shaped blood stain on the inside of Andrew’s boot, where she had hidden the murder weapon.
On 19 December, Tracie Andrews was charged with the murder of Lee Harvey.

When was Tracie Andrews released from prison, and what do we know about her life now?
Andrews denied the murder and the case when to trial at Birmingham Crown Court in July 1997.
After a month-long trial, she was found guilty on 29 July 1997 and sentenced to life in prison with a minimum of 14 years.
Sentencing her Mr Justice Buckley said: “The jury has found you guilty on very strong evidence of murder.
“Only you know precisely what went on that night but we have all seen the awful consequences.
“Certainly it has been a tragedy for all concerned and I feel deeply for the families on both sides.”
Two years later, Andrews admitted while in prison to killing Mr Harvey but claimed it was self-defence.
Fourteen years after her sentencing, Andrews was released from Askham Grange Prison near York in 2011. She had served the minimum term of her sentence.
She adopted the name Tia Carter and then Jenna Stephens, had surgery to alter her jawline and moved to a southern coastal town.
In 2017, she married bouncer Phil Goldsworthy, who she had met in the bar where she worked, and took the name Jenna Stephens Goldsworthy.
