Gerald Dube (36), who was employed by his cousin, Ms Patricia Majoko, at her law firm as a file clerk and stayed with the family at their residence in Francistown, ran amok after she fired him from the job and he became embittered and murdered the four on September 13.
Media reports from Botswana say the Department of Prisons and Rehabilitation confirmed Dube’s execution in the early hours of Friday.
Ms Majoko and her two sons, Amotjilani (5) and Dumisani (7), as well as the maid, Ms Lindiwe Ncube, were Dube’s victims. The deceased were found dead on the morning of September 14 at their residence.
Dube appealed against the High Court ruling, but the Court of Appeal upheld the ruling.
The death sentence was passed by the High Court in Francistown on June 14, 2007 after he was charged with four counts of murder.
A post-mortem carried out on the deceased persons, who were all Zimbabweans, indicated that they were hit on the head with a blunt object causing some fractures of the skull along with some multiple lacerations.
Dube had pleaded not guilty to all the counts. During trial, he had applied for the presiding judge, Justice Moses Chinhengo, to recuse himself from the case since they were both Zimbabweans. His application was quashed because "it was not a basis for recusal". Since then, the case had been adjourned several times. The prosecution insisted that the murder was premeditated.
"The motive derives from the accused pretending that he was a lawyer. (When he was found out) he was dismissed from the Majoko firm. He was deprived of the motor vehicle assigned to him by the company on September 10, 2001. He lost his home.
"Basically he was vagabond," argued the prosecution. "He deliberately devised means to go and kill Ms Majoko."
Dube’s lawyer, Mr Ookeditse Maphakwane, pleaded that his client suffered epileptic fits, which he held accountable for his behaviour on the day that he killed his relatives.
He said Dube suffered a fit on September 7, 2001 running on to "the following days".
"The accused has been consistent that he did not know what happened. He never denied anything. This indicates his frankness and honesty of how he came to be involved," submitted Mr Maphakwane.
