Andrew Chimboza has pleaded guilty to the murder as part of a plea agreement.

Cape Town - A Zimbabwean who mutilated his ex-client's lover poses a high level of risk to society and has little chance of being rehabilitated, the Western Cape High Court heard on Monday.

Police psychologist Major Hayden Knibbs came to this conclusion after interviewing 35-year-old Andrew Chimboza and looking at his trial transcript.

He was presenting his report to the court to help it impose an appropriate sentence.

He testified that during the clinical interview, Chimboza showed a lack of remorse for killing 62-year-old Mbuyiselo Manona last year, and placed the responsibility on Manona's lover, who was Chimboza's former client.

“He blamed her for inviting him (to her house) because she should have known that her boyfriend would attack him,” Knibbs said.

Chimboza, who moved to Cape Town from Zimbabwe six years ago, recently pleaded guilty to the killing as part of plea agreement.

He stated in his plea explanation that he stabbed Manona to death at the home of a former client last June, after a disagreement.

He alleged Manona attacked him with a knife. He retaliated by kicking Manona in the groin, stabbing him in the neck with a fork and then repeatedly stabbing him in the neck, chest, and abdomen with a knife.

Manona had apparently accused Chimboza of having sex with his partner.

He died from deep incisions to the neck, chest and abdomen, and blunt force injuries.

The doctor who performed the post mortem was presented with a bag containing neatly diced pieces of Manona's heart.

Knibbs said Chimboza regretted the position he was in and showed disappointment.

However, his focus remained on the crime's consequences for him rather than for the victim or his family.

When pressured in the interview, Chimboza evaded the topic with silence and did not maintain eye contact.

This behaviour seemed to indicate a threatening tendency of avoidance that was unpredictable and could escalate into conflict.

The psychologist listed a number of factors that increased the risk of re-offending, including a past conviction for assault and a lack of remorse.

In his favour was that he had pleaded guilty.

Knibbs recommended that Chimboza take part in anger and violence programmes while in prison, and have regular psychotherapy sessions.

The clinical report presented in court on Monday would be included in a file for an instance where parole was considered in future.

Knibbs will be cross-examined on Tuesday.
