A Senegalese man, who stabbed his South African girlfriend, more than 10 times before severing her head, says he regrets what he did.

A Senegalese man, Elhadji Adama Kebe, who stabbed his South African girlfriend, Sibongile Zenzile, more than 10 times before severing her head, has said he regrets what he did.

33-year-old Kebe, who arrived in South Africa from Senegal in 2016, pleaded guilty in February to killing Zenzile, 29, in their Kempton Park, Johannesburg flat on April 25, 2019.

Kebe left her head in the refrigerator and was arrested at a shop he ran not far from their flat the next day. He also pleaded guilty to a charge of violating a corpse.

Sentencing proceedings began in the high court in Johannesburg on Wednesday, where Kebe presented evidence in mitigation of sentence.

When asked by his lawyer, Innocent Mthembu about how he felt about killing Zenzile, Kebe cried and said he regretted everything he did.

"Sibongile was my girlfriend and accomplice and we did everything together. I deeply regret what happened,” said Kebe.

Prosecutor advocate Enock Makua, however, asked Kebe whether he would agree that he brutally killed Zenzile. Kebe said he accepted that he had killed Zenzile.

Makua said the question he asked was whether Kebe agreed that he brutally killed her. “Her head was completely chopped off. Would you not say this was a brutal act? If you show somebody the photos of the deceased with the head completely chopped off, that is a very brutal act,” said Makua. Kebe agreed.

Makua questioned how Kebe could go on and open his shop the next day and operate as if nothing had happened. Kebe said he was confused and could not stay at home.

"I do not know what happened to me that day. I could not stay at home as I could not see the body. I had no other place to go other than the shop. Even at the shop, I was confused. I knew I would be arrested. I was not even able to run away,” said Kebe.

Kebe agreed with Makua that he needed to be punished for the crime.

The prosecution called Zamelani Ncancashe, Zenzile’s stepfather. Ncancashe told the court that after her murder, the health of Zenzile’s mother, his wife Buyiswa Ncancashe, deteriorated and she now suffers from a heart condition.
