A postmortem
will be conducted on the body of slain Wells Fargo Human Resource Manager
Willis Onyango Ayieko to establish how he died.
This will
also form the basis of the case detectives are preparing.
Sources aware
of the probe revealed they have a clue on the motive and hope to make arrests
soon.
The autopsy
will be conducted Tuesday in Nairobi where the body was moved to as
investigations go on.
Among those
so far grilled include two M-Pesa agents who operate in Siaya.
This is
after it emerged the killers of Ayieko withdrew money from his mobile phone
through mobile banking.
The
agents are supposed to help detectives identify the men who withdrew at least
Sh100,000 in different locations in Siaya between October 19 and 20.
A team
of detectives from Nairobi joined those on the ground on Thursday and announced
they are pursuing good leads into his brutal murder.
Police
are investigating murder and robbery with violence in connection with the
incident.
Ayieko was a licensed gun
holder. His pistol with 14 bullets was among the valuables stolen from him.
Ayieko’s
body was discovered in Mungowere stream in Yala, Siaya County on October 23 at 2 pm.
The
family had reported he was missing on Monday, October 21.
Police said the body was decomposed when it was
discovered by a student.
It had
bruises on the face and stomach indicating it was dragged on a rough surface.
The body
was half-naked and seemed to have been tortured elsewhere before being dumped
at the scene.
The
killers then drove his car to Sabatia area, in Kakamega, which is a few
kilometres away and abandoned it on the roadside.
Ayieko
went missing last Friday, October 18 after attending a burial vigil event in
Gem, Siaya County.
He had
stayed until about 10 pm before he left the funeral never to be found alive.
The family said he had left his home in Nairobi and informed them he
would be back on Monday as he was to attend two funeral events.
He flew
out at about 1 pm and picked
up his four-wheel drive car that was waiting for him.
After
running a few errands in Kisumu, he drove to a funeral vigil in Gem, Siaya
County.
His car
had a dash camera and tracking device.
Investigators
have pieced together Ayieko’s last moments before his body was discovered
almost five days after his abduction.
According
to logs Ayieko left Nyamninia at around 10:15 pm on Friday and drove 13
kilometres to Nyabeda centre.
He is
believed to have been hijacked on this stretch by people who lay for him.
After about an hour, detectives believe the vehicle, which likely had Ayieko and his abductors on board by then, was moving between Regea, Nyamninia, and Muhanda centres.
It then proceeded to Dudi centre, where it remained
stationary between 11:57 pm and 3:44 am on Saturday.
The car later circled back to Regea, where it stopped for eight minutes.
Police
state that this was the last time his phone was traced. It however went on and
off on Sunday, briefly.
CCTV footage shows the car being driven towards
Kakamega.
At 6:04
am on Saturday, the vehicle was seen diverting at Sabatia Centre, where it was
later abandoned.
The people who hijacked and later
murdered Ayieko tried to hide their identities.
Detectives say preliminary
findings show whereas Ayieko’s four-wheel drive car had a working dash camera,
it was switched off or disabled on Friday, October 18 night.
This, according to police
shows those who took him were aware of the camera and made efforts to disable
it or hide their identities.
Two men who dumped the car in
Sabatia few kilometers away from where the body was found wore caps and never
raised their heads while leaving at the scene.
They parked the car next to a
petrol station and opened its bonnet to suggest there was a mechanical problem
before walking away carrying a bag.
The bag is believed to have
been containing Ayieko’s personal belongings and other valuables.
Police want to talk to his
colleagues at the current workstation and former ones as part of the probe
into the murder.
