Involvement in the Murder of Monica Kimani
Monica Kimani was a 28-year-old businesswoman who had made a fortune in South Sudan, where she ran a family-owned company that supplied tents, water, and fuel to NGOs and government agencies. She was found dead in her apartment in Nairobi on September 20, 2018, with her throat slit and her body tied up in a bathtub. She had just returned from Juba, where she had allegedly received a huge amount of money.

The main suspect in her murder was Jowie Irungu, who was identified by several witnesses as the last person to see her alive. He had visited her at her home on the night of September 19, 2018, using a fake ID card. He allegedly killed her after she refused to give him some money that he had requested. He then fled the scene, leaving behind his jacket and a bullet wound on his chest, which he claimed to have sustained in a robbery attempt.
Jowie Irungu was arrested on September 25, 2018, and charged with the murder of Monica Kimani. His ex-fiancé, Jacque Maribe, was also arrested and charged with being an accessory to the murder after the police accused her of trying to conceal evidence by burning Jowie’s clothes and giving false information. They both pleaded not guilty and were remanded in custody, pending trial.
Trial and Conviction
The trial of Jowie Irungu and Jacque Maribe began in June 2019, before Justice Grace Nzioka of the High Court. The prosecution presented 34 witnesses and various exhibits, including CCTV footage, DNA samples, phone records, and ballistic reports, to prove their case. The defense also presented their witnesses and evidence, including an alibi for Jowie and a psychiatric report for Jacque.
On February 9, 2024, Justice Nzioka delivered her verdict, finding Jowie Irungu guilty of the murder of Monica Kimani, and Jacque Maribe not guilty of the same charge. She said that the prosecution had adduced adequate evidence and met the threshold to prove that Jowie Irungu had intentionally killed Monica Kimani, without giving her a chance to survive.
She also said that Jacque Maribe had been wrongly charged and that she should instead face prosecution for giving false information to the police. She acquitted her of the murder charge and set her free. She ordered Jowie Irungu to remain in custody until he was sentenced on March 8, 2024.
Jowie Irungu is a man whose life took a dark turn when he killed Monica Kimani, a young and successful businesswoman, in cold blood. His actions not only ended her life, but also ruined his own, and that of his ex-fiancé, Jacque Maribe, who was dragged into the case by association.
He is now facing a possible death penalty or life imprisonment for his crime, while Jacque Maribe is trying to rebuild her career and reputation after being acquitted. The case has been a lesson for many Kenyans, who have followed it with keen interest and mixed emotions. It has also exposed the dangers of greed, lust, and violence, and the need for justice and accountability.
