Police have started investigating the mysterious death of Nairobi businessman and politician Francis Kiambi Kiriro alias Matanka who was found dead at his house in the leafy Karen suburb in Nairobi.

A police report says Kiambi’s wife Mary Waigwe Muthoni reported his death only hours after she allegedly declined to be his guarantor to secure a Sh2 billion business loan.

Muthoni is said to have informed the police that she came back home with her late at midnight on Monday after reveling at an entertainment joint at Karen shopping centre.

The report says the 50-year-old businessman slept in a different room from his wife after the row over the loan only to be found dead in the morning after vomiting beside the bed.


“They each spent the night in different rooms and the deceased never woke up since then, but could be heard snoring throughout the day and night and had vomited in his bedroom. It was until today at around 0600hrs when she went to check on the deceased and she found him lying dead on his bed with some vomits beside the bed,” reads the police report.

A doctor from the nearby Karen Hospital confirmed Kiambi’s death at 9:02am Monday, with police establishing they did not find any visible signs of injury on the body of the deceased.

Police are combing the house and Karen entertainment joints to trace the last steps of the businessman, who was unsuccessful in his bid to become Tharaka Nithi County Senator.

On August 27, 2021, KRA arraigned Kiambi, who was then Director of Patiala Distillers Kenya Limited, alongside his wife Muthoni at the Milimani Law court to respond to charges of selling alcoholic beverages affixed with counterfeit excise stamps to distributors.

Appearing before Chief Magistrate Francis Andayi, he faced a count of selling Excisable Goods affixed with counterfeit excise stamps contrary to section 40 of the Excise Duty Act 2015 and Regulations 30(1) (g) as read with Regulations 30(2) of the Excise Duty (Excisable Goods Management System) Regulations, 2017.

Kiambi denied the charge and was released on a Sh1 million bond and a surety or cash bail of Sh500,000.

While conducting compliance checks on shops along Mwiki-Kasarani Road in Nairobi, KRA enforcement officers found 178 bottles of Blue Ice Vodka, which are manufactured by Patiala Distillers, affixed with fake excise stamps at a shop named Nice Link Dealers Limited.
