Detectives investigating the murder were torn between charging a car hire services operator as an accomplice in the killing or turning him into a state witness after it emerged his testimony might hold the key to blowing open the case.
A forensic analysis of the phone of Wambui’s husband, Joseph Kori, as well as witness statements from people who have provided an alibi for him made it difficult for investigators to pin the murder on him.
In his statement given to detectives from Directorate of Criminal Investigations (DCI) in Juja, Mr Kori who was initially thought by the police to have participated in his wife’s murder said he last talked to her at 4 pm on the day she was killed. He claimed that he hang up the call after his wife informed him that she was with Judy Wangui, believed to be Kori’s lover.
He further told the police that he neither called his wife or lover after that brief phone call as he did not want to escalate what was already shaping up to be a day of drama between him and his wife.
Kori had further claimed that he informed Wambui’s parents that she was not in the house on reaching home shortly before midnight on January 26.
Additionally, it is said that people who were with him in Ngong on the night of the murder have corroborated his statement about his whereabouts.
The fresh twist now means that the police will charge Judy Wangui with the murder. Judy was Mr. Kori’s lover. She had spent the day merry-making with Wambui before she later killed her at her apartment at Fourways Junction. According to police, she hit Wambui on the head with a pressure cooker multiple times before strangling her.
