The death of Bilyaminu Bello
On November 19, 2017, Bilyaminu Bello died after a violent incident at the Abuja home he shared with his wife, Maryam Sanda. Early police reporting treated the death as a suspected homicide and the Federal Capital Territory Police Command opened an investigation.
Within days, prosecutors charged Sanda with culpable homicide punishable by death. Reporting on the original charge alleged that Bello had been stabbed during the incident. Because early accounts varied in describing the precise weapon, this archive treats the fact of the fatal stabbing and the later judicial findings as more reliable than competing early descriptions.
A long criminal trial
Sanda pleaded not guilty and the case moved through a trial that lasted more than two years, with multiple adjournments and contested evidence. On January 27, 2020, Justice Yusuf Halilu of the Federal Capital Territory High Court convicted her of culpable homicide and imposed a death sentence.
Channels Television's reporting on the judgment described the court as finding that the prosecution had proved Sanda responsible for Bello's death. The conviction was therefore more than an arrest or accusation: it was a trial judgment after a contested prosecution.
The Court of Appeal
Sanda challenged the conviction. On December 4, 2020, the Court of Appeal in Abuja dismissed her appeal and upheld the High Court judgment. The appellate court held that there was no basis to set aside the conviction and sentence. Her counsel then announced an intention to take the case to the Supreme Court.
The 2025 clemency controversy
While the Supreme Court appeal was still pending, President Bola Tinubu's government included Sanda in a 2025 prerogative-of-mercy exercise. An official State House instrument dated October 21, 2025 listed her death sentence as reduced to a 12-year term on compassionate grounds, citing her time already served, conduct in custody and the interests of her children.
The clemency decision drew public controversy and became legally important because the criminal appeal had not yet been concluded. The later Supreme Court ruling directly addressed that overlap between executive mercy and a live judicial proceeding.
The Supreme Court ruling
On December 12, 2025, a five-member panel of Nigeria's Supreme Court dismissed Sanda's appeal by a four-to-one majority. Multiple Nigerian news organizations reported that Justice Moore Adumein, delivering the lead judgment, held that the prosecution had proved the case beyond reasonable doubt and that the Court of Appeal was right to affirm the trial court.
The Supreme Court also faulted the executive intervention while the appeal was pending. Contemporary reports described the ruling as reinstating or leaving in force the original death sentence. Whatever the separate constitutional debate over clemency, the central criminal-law point is clear: Sanda's conviction survived the full appellate process and became final at Nigeria's highest court.
Why this case is classified as solved
Crime by Region does not mark a case solved merely because a person was arrested, charged or widely suspected. This case is classified Solved / Adjudicated because the trial court convicted Maryam Sanda, the Court of Appeal upheld that conviction, and the Supreme Court dismissed her final appeal in December 2025.
The archive separately records the 2025 clemency dispute because punishment and criminal responsibility are distinct questions. Executive action affected the sentence, while the Supreme Court ruling resolved the criminal appeal.
