Omar Lali, the boyfriend of Keroche Breweries heiress Tecra Muigai, has been charged in a Lamu court over her murder.
She died on May 2 at a private house in Shella, Lamu Island where she was staying with Mr Lali.
After falling, a source said, Tecra was taken to a local dispensary and later airlifted to Nairobi for treatment, but she succumbed to her injuries.
Following her death, Mr Lali was arrested by police on suspicion that he had pushed Ms Muigai to her death.
There were reports that there was an argument between them before she fell, a claim that Mr Lali's lawyer has vehemently rejected.
A court in May had rejected an application to continue holding Mr Lali in detention despite an application by the Director of Public Prosecutions (DPP) and the Directorate of Criminal Investigations (DCI) .
Lamu Principal Magistrate Allan Temba had refused to extend the pre-trial detention on various grounds.
