Wangui then left using the deceased’s car and left it around Homeland Hotel in order to pick the hired car she had left behind.

Mathenge told the detectives that when they arrived, he found Wambui had died.
Mathenge claims he was forced to carry the body and put it the back seat of Wambui’s Mercedes. They then drove towards Ruiru with him driving his Voxy and Wangui driving the deceased’s car.
It is alleged they dumped the body in a dam in Ruiru and left for Githunguri where they left Wambui’s Mercedes Benz. Police said Mathenge and Wangui drove back to Four Ways Junction and arrived around 5am.
It is said Kori arrived at their TRM home around 10pm and after missing his wife, he texted her, telling her to have fun and not to return home.
It has also emerged that Wambui had texted her husband Joseph Kori telling him to rush to Wangui’s home probably after the argument.
The following day, Kori told detectives he woke up to find reports on social media that a woman’s body had been found dumped around Kiambu’s Courtesy Dam.
