Two M-Pesa agents have been questioned as part of the ongoing investigation into the murder of Wells Fargo’s Human Resource Manager, Willis Ayieko.
Investigators revealed that Ayieko’s killers accessed funds from his mobile account using mobile banking services.
The agents are now assisting detectives in identifying the individuals responsible for withdrawing over Sh100,000 from Ayieko’s account at various locations in Siaya between October 19 and 20.
Detectives handling the case report significant progress in the investigation.
An autopsy is set to take place at Nairobi’s Lee Funeral Home to further examine the circumstances surrounding Ayieko’s death.
A specialized team from Nairobi joined local authorities on Thursday, confirming they are following promising leads on the case.
Ayieko, a licensed gun holder, was found with his pistol missing, alongside other stolen personal items, suggesting both robbery and murder as possible motives.
His body was discovered on October 23 in Yala’s Mungowere stream, Siaya County, showing signs of severe trauma.
A student who spotted the body reported it was partially decomposed, with visible bruises on his face and abdomen, indicating he may have been tortured before being dumped.
Investigations show that Ayieko had gone missing on Friday, October 18, after attending a funeral vigil in Gem, Siaya County, and was last seen leaving the event at around 10 p.m.
The family reported him missing on October 21 after he failed to return to Nairobi as planned.
According to police, Ayieko had traveled from Nairobi to Kisumu by plane, collected his vehicle, and headed to the vigil.
Forensic analysis of his vehicle’s tracking and dash camera data reveals that Ayieko left Nyamninia around 10:15 p.m., driving toward Nyabeda.
Detectives suspect he was intercepted along this route, with his vehicle subsequently moving through nearby locations such as Regea and Muhanda.
At Dudi Centre, the car remained parked for several hours before moving to Regea once more, where it was last tracked.
CCTV footage later captured the vehicle in Kakamega’s Sabatia area, where it was abandoned on the roadside with signs of tampering to suggest mechanical failure.
Authorities report that two men were seen leaving the vehicle, covering their faces and carrying a bag believed to contain Ayieko’s belongings.
The dash camera on Ayieko’s vehicle had also been disabled, indicating an attempt by his assailants to evade identification.
Investigators are now reaching out to Ayieko’s colleagues as they continue to build the case.
