The presiding judge, Justice Ubale Taura, said the suspect was arraigned on three counts of criminal conspiracy, kidnapping and culpable homicide.
The suspect admitted before the court that he and two others, Adamu Sabo and Usman Idrith committed the offences.
The offences were said to contradict sections 97, 221, and 273 of the penal code.
Justice Taura sentenced Buba to death by hanging for culpable homicide, five years imprisonment for the offence of criminal conspiracy and 10 years imprisonment for kidnapping.
The two other suspects who were arrested for alleged involvement in the kidnapping and killing of the boys were, however, discharged for lack of evidence to justify Buba’s claim that they were his accomplices.
Speaking with NAN after the ruling, Buba said he and his colleagues from Taraba kidnapped the boys and request for N5m. He explained that they decided to kill their victims following their relations’ failure to provide the ransom in good time.
Datti said the victims’ relatives were able to raise only N3,350,000, adding that they killed the hostages after collecting the ransom.
The convict claimed he got only N10,000 from the ransom as his colleagues fled to Taraba immediately after collecting the money.
