The late Boise was uncle to Minister of State for Petroleum Resources Dr. Ibe Kachikwu. Thirty-two-year-old Sunday Luka, a driver; Danjuma Kaika, 37; and Luka Agu, 33, killed the victim in his farm on June 9, 2014, and stole away his Kia Rio vehicle.
The defendants, who used to be labourers in the deceased farm, were charged to court on a four-count charge.
Justice C.I. Ogisi, while delivering the verdict, said the punishment for their offence was mandatory, and had no discretionary power to mitigate the sentence.
Ogisi, who sentenced the first and second accused on all four counts charge, however, discharged the third on counts two and four. But he was sentenced on counts one and three.
Justice Ogisi held that the court agreed with the prosecution counsel, Pollen-Ezeana-Ejiofor Esq, who urged the court to convict the defendants.
Earlier, the prosecutor said Boise was attacked with woods and other weapons, and his body thrown into a deep dry well.
The court also heard that two of the defendants used logs and cement blocks to cover the body in the well and took his Kia to Nasarawa State.
He said that they were arrested while trying to sell the car.
The deceased’s eldest daughter, Mrs. Magdaline Nkechi Esenwa, who was in court, was satisfied with the judgment. She rolled on the ground in happiness.
Esenwa described the judgment as justice for her late father, who was kind and caring even to his killers.
