Businessman George Mwangi, the husband of Kiambu-based politician Gladys Chania, was hit with a blunt object on the head, an autopsy has revealed.
A postmortem conducted at Kenyatta University Funeral Home also revealed that Mwangi struggled to defend himself from the killers as some of his fingers had fractures.
The autopsy that was conducted by chief government pathologist Johansen Oduor also revealed that Mwangi, whose body was found dumped in Kieni Forest, was hit on the back several times.
Earlier, a row between Chania's children and Mwangi's family had erupted over who should be given access to the body for the burial.
Jane Wambui, Mwangi's sister, said the two parties later agreed to have representatives who would witness and sign removal of the body from the morgue.
As they prepare to inter his body, the family of Mwangi sustained calls for justice, insisting that the killers must be brought to book and punished for killing and leaving their son to be eaten by wild animals.
A burial permit has been issued to the family, though a burial is yet to be announced.
This happened as Chania, alongside Morris Mbugua, a casual worker, continue to serve their seven days in remand to allow detectives conclude investigations into their alleged involvement in the murder of Mwangi, an engineer who was set to fly back Rwanda where he had been serving as a contractor.
Chania, who had been married to Mwangi for 20 years, is suspected to have planned the murder after she learnt about her husband's alleged love affair with a secretary at a local school.
Police say the politician identified Mwangi at the morgue days after she reported him missing at Mwea and Gachege police posts in Gatundu North, respectively.
