This is the man police want to speak to about Vlakfontein murders

Police have confirmed that a man who posted an image of the inside of a fridge as his Facebook profile picture on Tuesday is being sought in connection with the gruesome discovery of seven bodies buried at a home in Vlakfontein in the south of Johannesburg.

Police told TimesLIVE that they were probing Sibusiso Ernest Khoza’s active Facebook page‚ saying that they wanted to speak to him in connection with the murders.

The fridge picture was posted just over 24 hours after the seven bodies were discovered – and after police had confirmed they were looking for Khoza.

"We are still looking for him. If he has nothing to hide‚ why doesn't he come forward?" police spokesperson Captain Mavela Masondo said.

Masondo authorised TimesLIVE to publish Khoza's pictures‚ saying that he was "a person that police are looking for who can help with the investigation". Khoza has not been named as a suspect in the multiple homicide.

On Monday‚ a stench at the house in Vlakfontein led the police to a gruesome discovery. They found the bodies of seven people – three women and four children – buried under a pile of sand in a bedroom in the house. Masondo said the children were aged between two and 11 years.

A man taken in for questioning in connection with the murders is believed to be a boyfriend of one of the women found dead.

Masondo confirmed that an investigating officer was looking into Khoza's Facebook account‚ and confirmed via text messages that the pictures on the profile were indeed of Khoza.

A post dating back to September 28 reads: "Forgive me Lord."

"U are already forgive. But u must serve the punishment (sic)‚" a comment read.

Khoza has come under attack from a number of Facebook users‚ who demanded he tell authorities what he knew of the events that occurred in the house.

In his bio‚ Khoza describes himself as: "I am a cool guy who love God. I love my job."

He also states that he studied at the New York Medical College and is a medical doctor at Johannesburg General Hospital‚ now known as Charlotte Maxeke Hospital.

Khoza had apparently started living with the family three months ago‚ under the false pretense that he was a long-lost relative.

He claimed that he was raised in an orphanage in Cape Town and was a doctor by profession after studying abroad. A relative of one of the victims told TimesLIVE that Khoza was welcomed because he had the same surname and looked like a decent person.
