The court has allowed police to detain key suspects Benjamin Saitoti, David Sempuan for 10 more days to conclude the investigations.
Detectives said Wambua received Sh2.7 million, just a week before she was killed, and withdrew Sh2 million a day before she disappeared.
Sleuths believe that the Sh2 million she withdrew and the large sums of money she was receiving from NLC, including an Sh6 million payment are part of the reasons she was killed.
According to detectives, the money was from her employer and was to be used to pay suppliers for a project she was overseeing.
Police believe that Saitoti and Sempuan have information that will help in leading them to the people who dumped the body in the forest.
Further, they were looking into these calls to establish whether there is any critical information that can help nail her killers.
So far, Wambua’s husband and several members of staff at the NLC have been grilled over her murder. More persons of interest are expected to emerge as the case advances.
Wambua went missing on March 12, and unfortunately, her body was found dumped in Ngong Forest the following day. She was buried on March 24 in Machakos County.
