He was the custodian of the fingerprints of all known criminals in the country. His word on the identity of fingerprint was final and could free or lead to the jailing of a suspected criminal.

Raphael Daudi Musau is a celebrated professional in fingerprints knowledge but is little known outside the detective circles. He unravelled the mystery of the unidentified body dumped in a desolate thicket deep in the Hyena infested Ngong Forest in March, 1975.

The late Josiah Mwangi Kariuki, then MP for Nyandarua North had been reported missing for days since March 2. The country had reached its breaking point as tension and fear reigned.

And when a set of fingerprints, lifted from an unidentified male adult were delivered at the police headquarters, they landed on the desk of the head of a little known department within Criminal Investigations Department.

It took only two days for the expert to unravel the mystery of the body, which had since been transported to the City Mortuary. The fingerprints belonged to J M Kariuki. "At first, the names Josiah Mwangi Kariuki did not mean anything to me. All I had done was to trace the identity of the owner of the fingerprints. Then the enormity of my discovery hit me. I realised that this was JM, the man who had been reported missing," recalls Musau.

Even as the report was discretely dispatched to Ngong Police Station, Kenyans’ worst fears had been confirmed.

Musau was then the officer in charge of Criminal Records Office Finger Print Bureau at the CID headquarters.

"This was a very sensitive national issue. I was not supposed to publicise the findings. A wrong move could have plunged the country into chaos. Remember at this time some newspapers were writing that JM was in Zambia," he recalls. Musau’s journey to the world of detectives and dactyloscopy (fingerprints) started in 1962 when he was employed by the then Central Registration Office, now known as National Social Security Fund (NSSF), as a fingerprint trainee.

Fingerprints expert

He was fresh from Kabaa High School where he sat Cambridge School Certificate. A year later, Musau was transferred to CID and posted to the finger print section.

He rose through the ranks and was ultimately gazetted as a fingerprints expert in 1968, qualifying him to testify in a court of law as an expert.

He also trained at United Kingdom’s Glascow Finger Print Bureau, where the trainers realised Musau was an expert. Interestingly, they instead gave him a class to teach for six months.

"When they realised that I was well versed in the field, they turned me into a trainer. I taught students from Jamaica, South Africa and Britain for six months," says Musau. He later proceeded to Scotland Yard for further training in scene of crime management for six months. With this qualification, he became a detective.

In 1978, he was transferred from the CID and instructed to establish the National Fingerprint Registration Bureau, which oversaw the issuance of IDs in the country. As head of the bureau, he recruited 6,000 registration clerks and 500 finger print technicians.

It is as a result of this exercise that Kenya was ranked second after USA as the country with the biggest fingerprints bank. The FBI has about 200 million fingerprint entries in the bank while Kenya has about 20 million. With his knowledge, Musau is pained by the fact that thousands of Kenyans are buried as unidentified and unclaimed yet there is a foolproof method of identifying them.

"After accidents some of the victims are taken to hospitals where they stay for days in a coma before dying. Why can’t the hospitals take their fingerprints and refer them to the National Registration Fingerprints Bureau?" asks Musau.

The police, Musau says, are afraid of taking fingerprints of dead bodies in mortuaries and that is why the unclaimed are referred to as unidentified.

Power of fingerprints

Abruptly, Musau interrupts the interview, produces his national identity card, which he scrutinises as he thumbs a dark smudge at the corner of the document and smiles. "This is all the identity you need. With a fingerprint, you can never go wrong. Not even the 10 fingers of my hands are identical. These fingerprints started developing when I was only four months old in my mother’s womb," he says.

He explains that no two people in the whole world share identical fingerprints adding that even the prints of each of the fingers of the same person have distinct characteristics. There are different types of chemicals used to develop latent prints deposited on different surfaces such as plastic, walls and papers.

"Once a crime is committed, a thief is always in a hurry and will leave a trace behind, however careful he is. Even after death, prints last for years. Even if a criminal peels off his fingers after a crime, it will only take three weeks for the skin and the finger prints to develop again," he explains.

Musau says if banks were to adopt fingerprints as a mode of identification, they would avoid losing the millions being stolen by fraudsters and forgers.

"Every time you write a withdrawal form or write a cheque, you deposit your prints there. In case the transaction is illegal, we can always trace the culprit," he says. "We have also been telling hospitals to take the fingerprints of all babies born in their wards. This way, there will be a record of even those Kenyans who are below 18 years," he advices.

Musau explains that besides fingerprints, palm, shoe soles and footprints can also be used to identify an individual.
