Sarah Wairimu, the widow of slain Dutch tycoon Tob Cohen, has suffered yet another setback after the High Court on Tuesday July 8, 2025, denied her bail for the third time, citing ongoing witness intimidation, flight risk, and interference with the crime scene.

Justice Diana Kavedza ruled that Wairimu will remain in custody at Lang’ata Women’s Prison until the conclusion of her murder trial, saying the interests of justice and public interest outweighed her right to personal liberty.

“It is my considered view that the principles of justice and public interest outweigh the accused’s right to liberty at this stage,” Justice Kavedza ruled. 

“The court must protect witnesses and preserve the integrity of the trial.”

Wairimu is charged with the murder of Cohen, whose body was discovered in a septic tank at his Kitisuru home in July 2019. 

However, she pleaded not guilty in February 2025.

Her latest bid for bail was a renewed application based on the fact that the prosecution’s two key witnesses had already testified in April this year.

However, Justice Kavedza dismissed the claim that this amounted to a significant change in circumstance.

“The court did not guarantee release once the witnesses testified,” the judge said.

“Instead, it merely opened the door for reconsideration, provided compelling circumstances were shown.”

One of the key grounds for the court’s decision to deny her bail yet again was Wairimu’s alleged repeated intimidation of a police officer, Corporal Pascal Buana, in open court. 

The officer testified in court that Wairimu whispered the phrase “shame on you” to him three times during proceedings.
