The untold story of Harrison Okumu, the man Kenyans came to know as Kisumu's serial killer — from the discovery of bodies in his Miguye compound to his violent death behind bars at Kodiaga Maximum Prison.
For a long time, Miguye village was just another quiet corner of Kisumu County — the kind of place where neighbors know each other's names and nothing much makes headlines. That changed the day a foul smell drifting from one compound refused to go away.
What villagers eventually uncovered would shake Nyanza region to its core, and give Kenya one of its most disturbing true crime stories: the case of Harrison Okumu, a man some would come to call the "Butcher of Kisumu."
According to court records from the time, Okumu — known locally as "Boy" — was arrested in 2013 after human remains were discovered in and around his compound in Miguye. What started as a foul odor complaint from neighbors turned into a police excavation that unearthed a horror no one in the area was prepared for.
Editorial note: Some accounts circulating online describe more than seven bodies exhumed from the compound. Original court reporting from the time ties Okumu's charges to a smaller confirmed number of victims, including a named case involving Shem Nyambok. We're presenting the verified figures here and treating higher totals as unconfirmed.
Okumu was formally charged with murder and appeared before the High Court in Kisumu under tight security. He denied the charges against him.
A mental health evaluation carried out during proceedings found him fit to stand trial — doctors reported that he was coherent, well-kept, and showed no signs of psychiatric disturbance.
But the case was anything but straightforward. His own lawyer raised urgent concerns about his safety in custody, citing threats against his life, and asked the court to have him moved to an isolated section of the prison. The judge ordered prison officials to guarantee his protection — an order that would later prove tragically insufficient.
Editorial note: Claims that the trial was delayed due to more than fifteen witnesses going into hiding are widely repeated in retrospective accounts but were not independently verified in the court records reviewed for this piece.
Life inside Kodiaga Maximum Prison appeared to weigh heavily on Okumu long before his case reached its conclusion.
In December 2014, he attempted to take his own life by setting himself on fire using a mattress and a matchbox inside his cell. He was rescued by fellow inmates and prison officers, then rushed to hospital with severe burns.
In a separate incident, prison authorities reported that he had climbed the facility's perimeter wall, in what was described as another attempt to end his life.
Despite both incidents, he was medically cleared to continue facing trial.
On May 20, 2015, the case reached its final, violent chapter — not in a courtroom, but in a prison cell. Okumu died following a fight with fellow capital-offense inmates at Kodiaga Maximum Prison. Prison administration reported that five other inmates were also injured in the same scuffle.
Three inmates were subsequently charged with his murder. His family did not stay silent — his father publicly said he intended to sue prison authorities, arguing they had failed in their duty to keep his son alive long enough to face justice — or answer for his crimes in full.
Editorial note: Reports describing Okumu's death specifically as strangulation, and claims that he was attempting to flee to Somalia when arrested in Mombasa, appear in some secondary sources but could not be independently confirmed for this piece.
Perhaps no detail captures the depth of Nyanza's collective horror more than what reportedly happened at Okumu's burial in Rabuor. Accounts describe angry villagers throwing stones at his coffin — a raw, unscripted act some framed as a form of traditional cleansing. No eulogies. No speeches. Just a community trying to expel the fear his name had come to represent.
