In a shocking turn of events, it has been revealed that Christopher Okello Onyum, the 39-year-old man behind the brutal killings of four young children at Gaba Early Childhood Day Care Centre in Kampala, had spent two decades living in the United States before returning to Uganda.
The horrifying attack, which occurred on Thursday in Makindye Division, Kampala, has sent shockwaves across the nation, leaving the community devastated and raising questions about Onyum’s violent past.
Onyum’s violent history goes beyond the tragic events at Gaba. In 2017, he was arrested after brutally killing his stepmother in the Lango sub-region, an incident that echoes the same kind of violence he unleashed on the children.
Onyum’s stepmother, Mzee Asuman Onyum’s second wife, became the victim of his rage in an attack that led to his arrest by Kwania Police. However, the mystery surrounding his release from police custody and his eventual departure from Uganda to the United States remains largely unexplained.
Authorities have failed to provide clear documentation on the circumstances under which Onyum was freed and allowed to travel abroad.
His time in the United States seems to have been a period of significant turmoil. Despite the previous violent incident in Uganda, Onyum managed to relocate to Northern Virginia, where he was enrolled as a caregiver in an elderly home. It is unclear how someone with such a violent background was able to enter the U.S. and live there for 20 years without raising major red flags.
Onyum’s past and the decisions that led to his departure from Uganda and his arrival in America are now under heavy scrutiny, with many questioning the ability of both Ugandan and U.S. systems to track individuals with violent histories.

Reports from the 2017 killing of his stepmother indicate that Onyum had been diagnosed with a mental disorder, potentially linked to his sickle cell condition.
This medical history was believed to have played a part in his violent tendencies, though mental health was quickly ruled out as a contributing factor to the Gaba Daycare murders.
Recent investigations into the daycare attack have pointed to Onyum’s premeditation, suggesting that he meticulously planned the assault on the children rather than acting impulsively due to mental illness. His actions indicate that he was fully aware of what he was doing and took calculated steps to carry out his plan.
Authorities have pointed to Onyum’s prior visits to the Gaba Daycare Centre as evidence that the attack was well thought out. He had been to the school several times before the fateful Thursday, possibly to survey the area and perfect his plan.
This premeditated behavior contradicts earlier claims about his mental state and suggests a far more deliberate approach to the murders. Onyum’s actions were not a random act of violence but the execution of a carefully constructed plan.
On the morning of the attack, Onyum traveled to the daycare from his apartment in Kyanja, a Kampala neighborhood where he had been living for a few weeks.
During the journey, he made an unsettling stop at the Old Taxi Park in the city center, where he purchased three large knives, which he later used to kill the toddlers.
Along with the knives, Onyum also bought two brand new padlocks, which he used to lock the daycare’s main entrance and another door leading to the administrative offices.
This method of locking the school’s entrances suggests that Onyum had intended to trap his victims and prevent any escape, making the attack even more chilling.
After purchasing the knives and padlocks, Onyum proceeded to the daycare where he paid part of the school fees for a child he claimed he would be enrolling at the center. This strange act of normalcy, paying Shs 180,000 as part of the school fees, has raised questions about Onyum’s motives.
Why would he go through the trouble of enrolling a child, only to murder several toddlers in the same institution? Some speculate that he may have wanted to blend in with the community and cover up his true intentions, while others believe it was an additional layer to his elaborate plan.
Once inside the school, Onyum carried out his grisly attack on the four children—Ryan Odeke, Keisha Otim, Gideon Oteko, and Ignatius Sseruyange. The victims, all aged between 1.5 and 2.5 years old, were helpless against his violent assault. Onyum, who had no children of his own, killed the toddlers in cold blood with no apparent reason other than a violent urge. The brutal attack left the entire community in shock and mourning, as the children had been nothing more than innocent bystanders caught in the crossfire of a deeply disturbed individual’s rage.
The way in which Onyum carried out the attack, using multiple knives and taking the time to lock the entrances to the school, shows a chilling level of preparation and organization.
The deliberate nature of the murders raises troubling questions about how a man with such a violent history was allowed to move freely and commit such a horrific act without being detected or stopped earlier.
Following the massacre, Onyum’s actions have been under intense investigation. Authorities are still trying to piece together the full timeline of events and understand why he returned to Uganda after spending so many years in the U.S. The circumstances surrounding his return from America are strange, to say the least.
Onyum did not inform his father, Asuman Onyum, about his return, despite the fact that his father had always wanted him to stay in the U.S. with his other siblings. The two men were reunited by chance at the father’s home in Bunga, and it was then that Onyum revealed he had grown disillusioned with life in America and wanted to return to Uganda to engage in farming.
In a surprising twist, Onyum’s father drove him to Nwoya, a district in the Acholi sub-region, where he was set up on a farm. However, Onyum’s interest in farming was short-lived. Within weeks, he abandoned the farm and secretly returned to Kampala, where he rented an apartment in Kyanja. This sudden change of heart and decision to leave the farm raises even more questions about his mental state and motivations.

Some have speculated that he may have been affected by external factors, such as political or economic pressures, that influenced his decision to abandon the farm and return to the city.
Onyum’s return to Kampala and his subsequent violent actions have led some to speculate that he may have been influenced by the political climate in the U.S. during the presidency of Donald Trump. Onyum’s abrupt departure from the U.S. and return to Uganda might have been a result of the Trump administration’s harsh immigration policies, which targeted migrants in similar circumstances.
While there is no official confirmation that Onyum was deported, the timing of his return and his subsequent violent outbursts have led some to believe that he may have been a victim of such policies.
The murders at Gaba Daycare Center have raised widespread concerns about public safety and the ability of both Ugandan and U.S. authorities to properly monitor individuals with violent histories. Onyum’s violent past, combined with his ability to travel freely and carry out such a devastating attack, underscores serious flaws in the systems designed to protect the public from people like him.
The case has sparked calls for greater oversight and stronger checks to ensure that individuals with violent backgrounds are properly monitored and prevented from committing further atrocities.
In the wake of the Gaba Daycare tragedy, the families of the victims are left to mourn the loss of their young children, while the community grapples with the shocking reality of what happened.
The murders have left an indelible scar on the nation, and as the investigation into Onyum’s past and present actions continues, many are left questioning how someone with such a dark and violent history was allowed to slip through the cracks and wreak havoc on innocent lives. The answers to these questions may take time, but the pain of those affected will last far longer than any investigation.
