Almost five years after the death of Dutch businessman Tob Cohen, the Director of Public Prosecution has found new evidence against Sarah Wairimu, his wife.
Reviewing the murder case, the DPP found that Sarah had a case to answer and directed her arrest.
According to the DPP, there is overwhelming evidence showing that Wairimu murdered her husband.

“Upon independent and thorough review of the new material, the DPP is satisfied that Wairimu was involved in the death of Tob Cohen.Ms Wairimu’s impending arraignment following her arrest on 23rd January 2025 comes after the DPP received new material about Mr Cohen’s death from the Directorate of Criminal Investigations (DCI),” the DPP noted on Thursday in a statement.
DPP Benson Ingonga approved the re-arrest after investigators expressed dissatisfaction with the decision by former DPP Noordin Haji to withdraw the murder trial.
This is the second time Sarah Wairimu has been arrested.
She was first arrested in 2019 when the Dutchman’s body was found in a septic tank on July 19 in the Lower Kabete Area, within Nairobi County.
She was however released after the case was withdrawn.
Haji had informed a Nairobi court of his decision to withdraw the case against Wairimu and her co-accused, Peter Karanja.
He stated that instead of pursuing the murder case, the court should order an inquest to be conducted at the Milimani Law Courts.
Wairimu and her co-accused denied the charges before High Court Judge Stella Mutuku and were released on a cash bail of Ksh2 million each.
Wairimu is currently detained at the Kilimani Police Station and is set to be arraigned in court.
