A man who had been reported missing was found dead at his house in Kayole, Nairobi, on Monday evening.
The 54-year-old had been missing since Saturday, police said, adding the
state of his body indicated he died earlier.
Officers were alerted by neighbours who said a foul smell emanated from the house.
They broke into the house since the man lived alone.
At Mukuru slums, two men were found dead in their houses, residents saying the circumstances
of their deaths were unclear.
The three bodies were taken to mortuaries and investigations launched.
