The hashtag #JusticeForTshego has been trending on Twitter in South Africa after the horrific killing of 28-year-old Tshegofatso Pule.
Her stabbed body was found hanging from a tree near Johannesburg.
She was eight months pregnant, local media are quoting police as saying.
There are high levels of violence against women in South Africa and last year President Cyril Ramaphosa said the country was one of “the most unsafe places in the world to be a woman”.
Crime statistics released last year showed that 2,930 adult women were murdered in a 12-month period from 2017 to 2018, which amounts to one murder every three hours.
Ms Pule went missing last week and her body was found on Monday, the Sowetan newspaper reports.
It also quotes police spokesperson Capt Kay Makhubele as saying that a murder investigation has been opened.
On Twitter, people have been urging the police to find the culprit, but they also question whether the justice system will serve Ms Pule properly.
Last year, a spate of murders of women that received a lot of publicity led to a series of demonstrations with people calling for more action to be taken.
Since then special sexual offences courts have re-opened – they have worked intermittently over recent years because of funding difficulties, reports the BBC’s Pumza Fihlani from Johannesburg.
More resources have also been directed towards both places of safety for survivors of abuse, as well as government-funded programmes aimed at changing men’s behaviour, our reporter says.
