DCI officers probing the murder of former Treasury official and her daughter on Friday, September 27, announced that they had been handed a crucial lead in the investigations.
73-year-old Judy Wanjiku Mwai and her daughter Catherine Nyaguthii Mwai were found dead inside their home at Golden Gate Estate in South B, Nairobi.
As it turns out, on September 21, the suspect had actually used the old woman's phone to call the police and taunt them over the murders.
”Nimeua. Sasa kujeni muniue (I have killed now come and kill me)“ the caller told police.
Detectives revealed that the suspect had dialled the police toll-free line 112 and given them the information about the murders hours before the bodies were discovered by a relative.
The Standard reported that the audio recording of the conversation between the caller and the police officer on duty was handed over to Nairobi area DCI officers probing the murder.
By Friday, September 28, the investigators had summoned a relative of the deceased to try and identify the caller's voice from the recording. Police believe the caller was a woman.
In the conversation that lasted one minute and 10 seconds, the caller told police that she was in South B and when questioned about her knowledge of the South C Police Post, she confirmed she knew it.
The conversation ended as the officer on duty tried to convince her to surrender by reporting to the nearest police station.
Wanjiku's sister was asked to record a statement with the police in which she stated that she last spoke to the deceased on September 21, at around 9.45 pm.
The conversation was on a wide range of issues including the health of the Wanjiku's husband who is currently admitted at a Nairobi hospital.
On that night, the ex-Treasury staffer spoke to five other people on her phone including a taxi driver and a family friend.
Call data confirms that her (Wanjiku’s) phone was in communication up to around 9.53 pm.
Postmortem examination on the body of Wanjiku indicated that she had been strangled.
Makadara DCI chief Henry Kiambati disclosed that investigators had made good progress but declined to comment on their findings.
