Deputy President Rigathi Gachagua's elder brother is dead.
Jack Reriani - his only surviving brother died last night.
Gachagua revealed news of his demise on social media but did not disclose his cause of death.
He says their last interaction was on September 13, during their inauguration with President William Ruto.
"My eldest bro, Jack Reriani. The news of your passing on last night hit me hard as I remain alone among the Kirigo sons.
"My heartfelt condolences to your family, the Kirigo family, the larger Gachagua family and the extended Reriani family. May the almighty God give your wife and son the strength to bear the loss. I love you big the way you have always loved me."
Gachagua says during their last interaction they made plans, and relieved their old days.
"We spent quality time for three days during our inauguration. You were so happy, jovial and full of life. We shared beautiful moments of our life back in the village. I had the opportunity to thank you for paying my school fees in high school. We agreed on your enhanced role to lead the Kirigo family in view of my national duties. We parted happily and agreed that I would come home after we settle down to discuss family matters. Little did I know that those beautiful moments we shared would be our last," the second in command wrote.
