Lawyer Paul Gicheru's family is yet to know the actual cause of their kin's death after autopsy results were inconclusive.

In the exercise conducted on Friday, September 30 it emerged that a further analysis needed to be conducted to conclusively determine the ICC suspect's cause of death.

Gicheru's postmortem was done by government pathologist Dr Dorothy Njeru in the presence of the family, its lawyer Senior Counsel John Khaminwa and the police. 

Homicide detectives from the Directorate of Criminal Investigations (DCI) and the medical team took some of the samples collected from the exercise for further analysis at the government chemist. 

It is still not clear when the laboratory tests will be completed and the results released to the public.

Gicheru's postmortem had been scheduled to take place earlier in the week, however, wrangles within the family saw the exercise delayed as the split factions resolved the stalemate. 

A section of the lawyer's family led by Gicheru's mother - Josephine Wambui, had demanded the excercise be done in their presence. Wambui wanted Gicheru's children, who were in the UK, to return home prior to the commencement of the exercise. 

"It is not easy for someone to just collapse and die. Police must probe what happened because my son never complained. He was not sick.," she maintained.

"I spoke to him last Friday and he told me he was doing okay. He then asked me if my other siblings and myself visit our elderly mother and I told him we do. He was very soft-spoken; he only cared about his family," she stated then.

The Internationa Criminal Court (ICC) suspect was found dead at his Karen residence on Monday night, September 26.

Gicheru was found foaming from the mouth, raising allegations that the lawyer may have been poisoned. However, family lawyer, John Khaminwa dismissed the allegations.

A staff who was present during his demise claimed that he spent the better part of the day in his bedroom, drinking his favourite white wine. 

Among the items collected from the deceased's house for analysis included CCTV footage, bedsheets, utensils used by the lawyer, and his office keys.
