But charities which help victims of honour crimes say the true extent of the problem is far worse than the statistics show, as every year hundreds of vicitms - normally women - are too frightened to report attacks or to give evidence in court.
Miss Goren disappeared 10 years ago after telling a friend she might be pregnant but justice caught up with her father after his wife “courageously” testified against him and lifted what was described as the “cloak of secrecy” which surrounds honour crimes.
A prosecutor said the case was a “wake-up call” to the authorities over the extent of the problem in this country, which campaigners say is growing because of the rise of religious fundamentalism.
Miss Goren and her family had nine contacts with police in the days before her death, during which they complained of violence by Goren, but officers had little understanding at the time of the concept of honour crimes and she was left at the mercy of her father.
The court heard that Miss Goren, whose Turkish Kurd family are Alevi Muslims, was drugged, tortured and then killed by her father after she fell in love with a Sunni Muslim twice her age.
Her body has never been found.
Goren, who adhered to what one police officer described as “outdated feudal beliefs”, was sentenced to serve a minimum of 22 years in jail as the trial judge condemned the “hideous practice” of so-called honour killings.
Miss Goren’s sister Nuray Guler told the court, the teenager had been “caught in the middle of two clashing worlds” and pleaded with police to stop other women falling victim to “this primitive custom”.
She expressed fears for the safety of her mother Hanim, whose evidence against Goren had put her own life in danger. “No one should fail to realise what this means within our culture,” she said.
“These people do not forget.”
Figures released by the Metropolitan Police show that in London alone there have been 129 honour-based crimes between April and October this year, compared with 132 in the whole of 2008/09, which in turn was double the number of the previous year.
The Home Office has estimated that there are an average of 12 honour killings each year in England and Wales.
