Detectives investigating the murder of business woman Mary Wambui are 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.  This is after 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 have made it diffcult for investigators to pin the murder on him.
