Is the well-dressed Richard Nyauza, a self-styled "Casanova", a murderer - the notorious Olievenhoutbosch serial killer who in cold blood killed 16 women?
This is the question Pretoria high court Judge John Murphy will decide on today.
The State is confident the 36-year-old "womaniser" is the same person who killed five women in 2002 and dumped their bodies along the Krugersdorp Highway near Olievenhoutbosch.
Prosecutor JP Marais told the court there is no doubt Nyauza is also the man who, three years later, continued the killing spree in the same area. The bodies of 11 more women were discovered barely 3km from where the others were found.
No bodies were found for three years between 2002 and 2006.
The court heard that Nyauza was in jail during this period, awaiting trial on a rape case.
He was freed at the end of 2005 after he was acquitted of rape. The first bodies in the second series of killings were discovered soon afterwards.
The killings continued until the police nabbed Nyauza in August last year when one of his alleged victims, who was left for dead, lived to tell the tale.
Jane Seremane told the court of her harrowing ordeal.
She was stabbed with a screw driver in her neck and face. She was dumped in a ditch after her attacker removed her panties. He did not rape her, but, thinking she was dead, left her there.
Seremane, who was pregnant at the time, not only lost her baby, but is now also blind in the one eye.
She had no doubt in her mind who her attacker was. She pointed Nyauza out in court as the person.
Meanwhile, a police expert on serial killers, Dr Gerard Labuschagne, believes that all 16 murders were committed by the same person. He said it was up to the court to decide whether this person was Nyauza.
He has being linked via his DNA to several of the bodies. This, Nyauza said, was because he slept with so many women.
Confronted with pictures of himself pointing out the various places where he had allegedly killed and dumped the women, Nyauza stuck to one answer: he was unconscious when the pictures were taken.
He said the police were that morning supposed to give him his HIV/Aid related medication, but instead they "poisoned him" - which caused him to lose consciousness.
Labuschagne testified that most serial killers have a "signature" - in this case it was adult black females targeted for a specific reason.
The State said this tied in with the Nyauza case, as he had contracted the HIV/Aids virus shortly before the killings started.
Nyauza, while pointing out the scenes to the police where killings had taken place, apparently told them that women did not have the right to live, as one had given him Aids.
The State argued that a sexual theme ran through 14 of the 16 scenes - the bodies were either left naked or with their underwear next to them.
The only argument in Nyauza's defence that his counsel could present was that the court should consider his version, namely mistaken identity. If convicted, Nyauza could face 16 life imprisonment terms.
