A mystery of a girlfriend and a string of denials emerged during the Friday defence hearing of the robbery with violence against Erick Muyera Isabwa, the main suspect in the murder of Kabete MP George Muchai.

Isabwa, also known as chairman, denied having any romantic relationship with his co-accused, Jane Wanjiru, despite the prosecution’s earlier claims that the two were involved in an affair.

The prosecution had put forward evidence suggesting that Isabwa and Wanjiru were living together at a rental house in Kinoo 87 Kiuru when he was arrested in connection with Muchai’s brutal murder that happened opposite Nairobi’s General Post Office (GPO) in February 2015.
