Family and friends of the late lawyer Evans Monari gathered at SDA church Nairobi on Thursday for his memorial service.
Monari died on October 4 at Nairobi Hospital where he was admitted following a long illness.
His brother Ken made the announcement through a message to the social media account that was raising funds for his medical bills.
"It is with profound sadness that I would like to inform on behalf of the Ogeto family that Evans has gone to be with the Lord. May the almighty God rest his soul in peace. Thank you for your continued support," Ken Monari said.
In attendance during the memorial service were First Lady Margaret Kenyatta, former Chief Justice David Maraga, former CJ Willy Mutunga, Interior CS Fred Matiang'i, former Education PS Belio Kipsang, ODM Secretary General Edwin Sifuna among others.
Nairobi county director of Youth Affairs, Walter Mong'are, alias Nyambane, was the master of ceremony.
Monari has been eulogised as a dependable, lovable and a caring man.
President Uhuru Kenyatta eulogised the lawyer as a dependable and a bright mind who solved cases he put his mind to with ease.
ODM leader Raila Odinga remembered him as a lovely and free-spirited man who covered his tough challenges with a warm smile.
"He has gone too soon, and our country is poorer with his departure. I wish peace and strength to his family. May he rest in peace," Raila said.
Chief Justice Martha Koome said the legal profession has lost one of its best advocates.
Monari rose to national prominence when he represented former police commissioner Hussein Ali when he faced crimes against humanity charges at the International Criminal Court.
