New details have emerged about Christopher Okello Onyum, the man behind the chilling murders of four young children at the Gaba Early Childhood Day Care Centre in Kampala.
Onyum, aged 39, was living in a rented apartment in the Kyanja neighborhood of Kampala at the time of the attack.
He accessed the daycare premises on Thursday, April 3, 2026, under the guise of enrolling a child but left behind a trail of devastation that has left the community reeling.
Onyum’s violent history and troubling behavior span several years, with his darkest chapter dating back to 2017, when he killed his stepmother in a similar act of brutality.
According to reports from Weekend Vision, Onyum’s stepmother, who was the second wife of his father, Mzee Asuman Onyum, met her tragic end in Kwania, located in the Lango sub-region.
Onyum was arrested at the time and detained at the Kwania Police Station. However, no clear records exist explaining how he was released or allowed to travel abroad, despite his violent past.
The mystery surrounding Onyum’s release and subsequent departure from Uganda has raised serious questions about the country’s justice system. After leaving Uganda, Onyum relocated to Northern Virginia, USA, where he settled with other members of his family.
During his time in the U.S., Onyum managed to secure a job as a caregiver in an elderly home, despite his violent history. This has led many to wonder how someone with a background of such severe violence was able to enter the United States and live there for an extended period without facing scrutiny.
In the aftermath of the Gaba Daycare tragedy, investigators have looked into Onyum’s mental state, with initial reports suggesting that his 2017 crime was linked to a mental disorder believed to have been induced by sickle cell anemia.
However, recent investigations into the daycare murders have ruled out mental illness as a contributing factor. Evidence now suggests that the attack on the children was not an impulsive act but rather a premeditated crime.
Onyum had been seen several times around the Gaba Daycare Centre in the days leading up to the attack, likely surveying the school and planning his actions.
On the morning of the attack, Onyum traveled to the daycare from his apartment in Kyanja, where he had been living for several weeks. On his way there, he made a disturbing stop at the Old Taxi Park in Kampala, where he purchased three large knives.
These knives were the weapons used to carry out the brutal killings of four toddlers—Ryan Odeke, Keisha Otim, Gideon Oteko, and Ignatius Sseruyange—who were between the ages of 1.5 and 2.5 years old. The children’s tragic deaths have sent shockwaves through the community, leaving parents and educators in disbelief at the senseless violence.
In addition to the knives, Onyum also bought two large padlocks, which he used to lock the daycare’s main entrance and another door leading to the administration block. This deliberate act of locking the school’s doors suggests that Onyum had planned the attack in advance, intending to trap the children and prevent anyone from intervening. This level of preparation indicates that the murder of the four children was not a random act but the execution of a well-thought-out plan.
Onyum’s strange behavior continued when he arrived at the daycare. He paid an advance of Shs 180,000 as part of the school fees for a child he claimed he was going to enroll at the school. This peculiar act, which initially seemed unrelated to the murders, further highlights Onyum’s ability to blend into his surroundings and hide his true intentions. The payment of the school fees could have been a tactic to establish credibility or to create the illusion of a normal, law-abiding individual.
Once inside the school, Onyum launched his attack. Armed with the knives, he mercilessly attacked the children, who were defenseless against his assault. The four toddlers were killed instantly, and their bodies were left behind in the wake of Onyum’s violent outburst.
Onyum’s actions have left the families of the victims devastated, and the community is struggling to comprehend the brutality of what happened at the daycare.
The murder of the four children has also raised concerns about the effectiveness of law enforcement in preventing violent individuals from re-entering society and committing further crimes. Onyum’s past, including his previous killing of his stepmother, should have been a red flag for authorities, yet he was able to travel freely between Uganda and the United States, living without detection for years.
The failure to adequately track and monitor individuals with violent histories has raised serious questions about the systems in place to protect the public from such dangerous individuals.
Onyum’s return to Uganda in late 2025 adds another layer of complexity to this case. Despite having lived in the United States for two decades, Onyum chose to return to Uganda, much to the surprise of his father, Asuman Onyum.
The elder Onyum had always hoped that his son would remain in the U.S. and build a life there, but Christopher revealed that he had grown dissatisfied with life in America and preferred to return to Uganda. He expressed a desire to engage in farming on family land in Nwoya District, a region in northern Uganda.
In a surprising twist, Onyum’s father reluctantly drove him to Nwoya, where he was set up on a farm to pursue his dream of farming. However, Onyum’s time on the farm was short-lived. Within a few weeks, he abandoned the farming project and secretly returned to Kampala, where he rented an apartment in Kyanja. This sudden change of heart and return to the city raises questions about what prompted Onyum to abandon the farm and resume his life in the urban center.
Some speculations suggest that Onyum may have been affected by external factors, including political pressures in the United States. There has been talk that Onyum may have been impacted by the deportation policies enacted under former U.S. President Donald Trump, which targeted individuals in similar circumstances. While there is no official confirmation that Onyum was deported, the timing of his return to Uganda and the abrupt shift in his behavior have led some to believe that he may have been a victim of these policies.
The tragic killings at the Gaba Daycare Centre have brought to light numerous issues, including the ability of individuals with violent histories to move freely between countries and the failure of systems to properly track and monitor these individuals. The events also raise serious concerns about the mental health and well-being of people like Onyum, who, despite his violent history, was allowed to live and work in the U.S. without facing any significant legal repercussions.
The families of the young victims are left with an overwhelming sense of loss, as they mourn the deaths of their children in the most senseless of ways. In the wake of this tragedy, many are calling for a deeper investigation into how Onyum was allowed to continue his violent ways and how authorities failed to prevent such an event from occurring. The need for stronger systems to monitor individuals with violent tendencies and ensure that they do not slip through the cracks is more pressing than ever.
As the investigation into Onyum’s actions continues, there are still many unanswered questions. How could someone with such a dark and violent past slip through the cracks of both Ugandan and U.S. authorities? What led Onyum to commit such a heinous act against innocent children?
And perhaps most importantly, how can society better protect vulnerable individuals and ensure that violent criminals are prevented from causing further harm? These are the questions that remain unanswered as the nation grapples with the aftermath of this horrific crime.
For now, the community and the families of the victims must try to come to terms with the devastating loss of their loved ones. The Gaba Daycare tragedy has left an indelible mark on the hearts of those affected, and the quest for justice continues as investigators work to uncover the full extent of Onyum’s actions and motivations.
