– Detective Constable Michaela Clinch, Greater Manchester Police
After 24 years of living with the terrible memory of being raped, I am absolutely delighted that finally, this brave woman has seen her attacker exposed and brought to justice.
"She suffered a terrifying ordeal at the hands of Howell that evening 24 years ago.
"She was brutally raped at knifepoint and I know it is an experience that left her emotionally scarred and traumatised.
"But she has shown tremendous courage, patience and tenacity and today, finally she can take some comfort knowing Howell has been convicted of this awful crime.
The victim, who was 25-years-old at the time, was raped on waste ground off Aspin Lane, Collyhurst, on 22 November 1989.
She was grabbed from behind by a Howell who was armed with a knife.
He held the weapon to her throat and subjected her to a terrifying attack.
An investigation was launched and forensic samples taken, but no arrests were made at the time.
In 2004, Greater Manchester Police's Cold Case Unit reviewed the case as part of Operation Advance, a nationwide review of unsolved rape cases using the latest DNA profiling techniques.
