The court found the duo guilty of poisoning Nasir, which led to his death. According to the prosecution, Lawal, a former guard, and Rabi'u, the cook, resorted to poisoning the former commissioner after failed attempts to steal from him.
A joint autopsy confirmed the presence of poison in Nasir's body. The court also sentenced another former guard, Sani Sa'adu, to five years in prison for concealing the truth about the murder.
However, the court acquitted Gift Bako due to insufficient evidence linking her to the crime. The lawyer for the convicts pleaded for leniency, citing the convicts' families and dependents.
The late Nasir served as Commissioner for Science and Technology during the administration of former Governor Aminu Masari and was also a former federal legislator.
