Akombe had said she is willing to testify at an inquest, if there is one, and likened the killers to Judas Iscariot.
At the start of August Akombe updated her Twitter profile picture with the quote: ""History will not be kind to us. So you have a moral obligation, a mission and a mandate, to speak up, speak out and get in good trouble. You can do it. You must do it. Not just for yourselves but for generations yet unborn."
The quote is by John Lewis, a civil rights leader who died last month.
Lewis was one of the "Big Six" leaders - which included Martin Luther King Jr - of groups who organized the 1963 March on Washington, and he fulfilled many key roles in the civil rights movement and its actions to end legalized racial segregation in the United States.
Akombe has said authorities are not willing to arrest Msando's killers, accusing the ODPP of laxity.
Three years ago, Msando's body was found in a thicket at Muguga Forest in Kikuyu — a killing that almost threw the August 8, 2017, polls a week way into disarray.
He had been tortured, his hands and arms and back cut. It was said a hand was broken because his killers wanted his password to the election results transmission system. The postmortem showed only deep cuts. He was strangled.
Msando had promised he would ensure the IEBC tech system in the 2017 elections was foolproof. President Uhuru Kenyatta's victory was later nullified by the Supreme Court citing irregularities in the process. He won, however, in a rerun.
Akombe, in a series of tweets, put the IEBC on the spot, saying Msando’s colleagues sold him out to his killers.
She had fled to the US, claiming her life was in danger, and returned to work for the United Nations there.
