A 66-year-old man was found early Sunday beheaded and his head thrown into a water tank with body dumped in a garbage pit.

Peter Ndung’u Kinyanjui, 66, who was a diabetic patient was living with his 42-year-old son, K24 Digital reported.

According to Grace Wambui, the man’s sister-in-law, they suspect that man’s son may have committed the murder since he suffers from mental health issues.

The son, identified as Samuel Kinyanjui, missed his monthly health check-up after tellings his relatives he couldn’t because his clothes were dirty, Wambui said.

She said that he was a cool person who never provoked anyone.

The man is still at large but police are searching for him.

The sad incident occurred at Ahero village in Maili Tisa, Bahati sub-county in Nakuru, Kenya.

Bahati MP Kimani Ngunjiri, who visited the family, decried a surge in the abuse of drugs and a high murder rate in the region.

“We have seen planting of bhang in some parts of Wanyororo. It is a worrying situation and we need to take more efforts in eradicating the menace,” Ngunjiri said.

Nakuru Senator Susan Kihika expressed concern over prevalent murder incidents in Bahati, many of them involving domestic disturbances.

“Last week we had an incident involving a sister and a brother and its worrying,” Kihika said.

The son is still at large and a search has been activated to nab him.
