KAMPALA, Uganda — The decision by Christopher Okello Onyum—sentenced to death for the murder of four toddlers at a daycare centre in Ggaba—to remain silent at a critical moment in his trial, when the court invited him to mitigate before sentencing, has become one of the most closely examined aspects of a case that has already shocked Uganda.
Presiding over the case, Justice Alice Komuhangi Khaukha underscored the significance of that moment, noting that the accused declined to speak even after repeated prompting.
“The accused person in mitigation. The Court asked him to say something in mitigation, but he chose to keep quiet,” the trial judge observed.
In criminal proceedings, mitigation is not a mere procedural formality. It is often the final opportunity for an accused person to influence judicial discretion, particularly in capital cases where the distinction between life imprisonment and a death sentence can hinge on expressions of remorse, personal circumstances, or explanations that humanise the offender.
Okello’s silence has therefore raised a central and enduring question: was it a deliberate legal strategy, or a costly miscalculation?
Under Ugandan law, the role of mitigation has evolved significantly since the landmark Susan Kigula & 416 Others v. Attorney General. That ruling abolished the mandatory death penalty and introduced judicial discretion, requiring courts to weigh aggravating and mitigating factors before determining sentence. In effect, sentencing became a calibrated exercise, with the accused’s own voice often forming a critical part of the balance.
Against that legal backdrop, Okello’s silence effectively left the court with a single, dominant narrative—that of the prosecution. Led by Chief State Attorney Jonathan Muwaganya, the state presented a case grounded in premeditation, digital forensic evidence, financial activity demonstrating cognitive clarity, and the extreme vulnerability of the victims.
Without mitigation, there was little to offset these aggravating factors, reinforcing the court’s conclusion that the case fell within what Justice Komuhangi Khaukha described as the “rarest of the rare.”
On the defence side, counsel—including Sarah Awelo—had attempted to construct a case around mental instability and personal background, pointing to health conditions and a troubled upbringing as factors that could reduce culpability.
However, the court found these arguments unpersuasive, citing the absence of expert psychiatric evidence and the accused’s demonstrated ability to plan, transact financially, and execute actions with precision. In dismissing the insanity defence, the court effectively closed one of the most consequential legal avenues available under Ugandan criminal law.
Legal analysts suggest that Okello’s silence may have been informed by appellate considerations. Statements made during mitigation can later be scrutinised on appeal, and any admissions or inconsistencies could undermine legal arguments—particularly those relating to mental capacity or procedural fairness.
By choosing not to speak, the defence may have sought to preserve a controlled record, free of statements that could complicate future proceedings.
Yet this approach is not without risk. In practice, Ugandan courts often treat remorse as a meaningful mitigating factor, even in cases supported by overwhelming evidence. Silence, particularly in a case involving the killing of young children, may be interpreted not simply as a legal posture but as an absence of contrition—an impression that can weigh heavily in sentencing.
With conviction secured and a death sentence imposed, the case now enters the appellate phase. Christopher Okello Onyum has been granted 14 days to file an appeal, initiating a process that will begin at the Court of Appeal and could ultimately reach the Supreme Court.
The defence is expected to challenge both conviction and sentence, focusing on potential procedural issues, the handling of evidence, and the rejection of the insanity defence.
However, the prospects of overturning the conviction appear limited. The judgment delivered by Justice Komuhangi Khaukha is understood to be detailed and firmly anchored in corroborated forensic and digital evidence.
Appellate courts typically defer to trial courts on factual findings unless a clear legal error is demonstrated. As a result, some legal observers believe that any realistic appellate success may lie in challenging the sentence rather than the conviction—arguing, for instance, that the death penalty was disproportionate or that mitigating factors were insufficiently considered.
Beyond the judiciary, the case also intersects with Uganda’s evolving stance on capital punishment. Although the death penalty remains lawful, its practical application has been significantly constrained.
Uganda has not carried out executions since 1999, creating what is widely regarded as a de facto moratorium. The Kigula decision further introduced safeguards, including the principle that prolonged delays in execution—commonly referred to as the “three-year rule”—can lead to commutation to life imprisonment.
In addition, the final stage of the process lies within the executive domain. The Advisory Committee on the Prerogative of Mercy may review the case and advise the President on whether to grant clemency, reduce the sentence, or allow it to stand.
This layered system has drawn sustained criticism from human rights organisations, including Amnesty International, which argue that maintaining death sentences without carrying out executions raises ethical concerns, particularly regarding prolonged detention under the threat of death and its psychological impact.

From a broader human rights perspective, the Okello case encapsulates a tension that continues to define criminal justice systems worldwide: the balance between delivering justice for egregious crimes and upholding evolving standards on the use of irreversible punishment.
For many Ugandans, the brutality of the offence strengthens calls for the harshest sanction available. For others, it underscores the importance of procedural fairness, consistency, and caution in the application of capital punishment.
As the appeal window opens, Okello’s silence remains a defining feature of the case—one that may yet prove consequential.
Whether the silence was a calculated legal decision aimed at preserving appellate options or a missed opportunity to influence judicial discretion, it has added a complex layer to a case that is likely to shape legal precedent and public debate in Uganda for years to come.
