The death of one of President Uhuru Kenyatta's brothers has remained a mystery, 40 years after it occurred.
The circumstances leading up to the demise of Peter Muigai Kenyatta are uncertain and the cause of death in 1979 is still unknown.
Muigai was Kenya's founding President Mzee Jomo Kenyatta eldest son with his first wife Grace Wahu.
His only sibling was the late Margaret Wambui Kenyatta who served as Nairobi's first woman mayor between 1970 and 1976.
President Uhuru is Mzee Kenyatta's eldest son with his fourth wife former First Lady Mama Ngina Kenyatta.
Born on November 20, 1920, Muigai died one year after the sudden death of his father on August 22, 1978.
Just before the First Family could come to terms with the demise of Kenya's founding father, the cruel hand of death struck again this time snatching the 58-year-old politician on October 28, 1979.
Muigai, who also served as Foreign Affairs Assistant Minister, died during campaigns for the 1979 general election in which he was defending his Juja parliamentary seat.
He had been elected in 1974 in a disputed poll where he unseated the incumbent Gitu wa Kahengeri.
"As fate would have it, Muigai died suddenly a few days to the 1979 general election, prompting the Electoral Commission to declare me elected unopposed," Kahengeri told the Standard in 2014.
The cause of Muigai's death was not immediately established and the postmortem results have remained out of the public domain to date.
In a perfect case of like father like son, the former Juja MP was also a polygamist who had five wives.
His fifth wife, Esther Njoki Muigai, died in a mysterious murder a few months after her husband's death in 1980.
