The State and Defence led closing arguments on Tuesday in the ongoing murder trial of Vicki Terblanche.
Former school teacher Reinhardt Leach already pleaded guilty to some charges against him.
State Advocate Marius Stander said the most problematic aspect was the murder, based on the conviction the state is asking for.
He highlighted the versions of Dylan Cullis, who accused Leach of smothering Vicki, to the version of Leach, who claimed the opposite, resulting in overlapping evidence, in essence, who smothered the deceased.
Stander argued that irrespective of what had happened in the room when Vicki died, one has to look at what transpired after her death, referring to Leach reporting Vicki as missing, selling her belongings and arranging to get rid of the body.
He further highlighted the evidence of the pathologist Dr Annemarie Mattheus and NMU Professor Johannes Bodenstuin, who both agreed that the combination of drugs found in her system would have caused her death.
Stander argued that the men in the house acted for a common purpose, stating case law.
Vicki's smothering was of no particular significance to the state in the trial against Leach.
Leach's defence Advocate, Jodine Coertzen, argued that her client testified honestly in that he admitted he first assisted the deceased in her request to get rid of her husband and then assisted the husband.
She said the fact that Leach was under financial strain and had just heard Vicki's baby was not his was a proverbial turning point for her client.
She said he did not do these things for financial gain but because he was hurt. She asked the court to sentence her client on his version of events.
Acting Judge Samson Dunywa had some questions about the firearm charge as it was still unclear what type of gun Leach had obtained. Leach had said it was a revolver, while Cullis testified it was a pistol.
Advocate Stander said the weapon was a revolver.
Dunywa had further questions about the so-called "perkies", asking if it was the Percocet that killed Vicki or if it was a combination of all the drugs in her system.
Both Stander and Coertzen said it had been a combination as the Percocet could not yet metabolise further than the deceased's stomach contents.
Acting Judge Dunywa will deliver judgment on Wednesday morning.
