Ms Wairimu, who maintains that she has nothing to do with Cohen's brutal murder, has filed a complaint in the court over Sh400 million house in Spring Valley.

The house, in which Cohen was found dumped in a septic tank, remains a crime scene. In the affidavits filed in court, Wairimu accuses Kinoti of going beyond his jurisdiction by investigating property ownership.

"I am aware that the second respondent through Kinoti has gone well beyond its mandate to publicize section 96 of the law in a manner that paints me as being guilty of the offence of murder and therefore locked out of my right to inheritance even before this court conducts my trial," she said.

"The respondent has clearly impugned my right to my matrimonial home."

Wairimu claimed that Kinoti is determined to hand over the keys to her matrimonial home to the 'purported beneficiaries' of her husbands alleged Will.

"After opening of the Will, Gabrielle and her husband had no further use for my husband and promptly left the country despite publicly stating that they wanted to accord Cohen a decent Jewish burial," she said.

Also, Ms Wairimu accuses two unnamed Kiambu politicians of claiming that they were owed Sh35 million by the late tycoon. She disputes the debt and wants its investigated.

The court on Thursday pushing her plea-taking to August first when Cohen's lawyers claimed that defense lawyer Philip Murgor was still an employee of DPP.
