Today was supposed to be a big day for Chris Msando - he was to oversee the public testing of the voting system which has been vaunted by the IEBC as key to eliminate vote rigging and to deliver a credible election.
Msando was reported missing on Friday, July 28 and was found on Saturday morning in the outskirts of Nairobi.
"Prior to his death, Mr Msando reported death threats to the central police station and the police did not provide him detailed security", it said.
Jubilee President Uhuru Kenyatta, NASA's Raila Odinga and six other presidential candidates will battle it out for the top seat in five days.
However, when his body was found alongside an unidentified woman moments after his vehicle was seen parked in Roysambu, Nairobi, the police ruled out any foul play leading to his death.
The postmortem results revealed that Msando was strangled to death by his killers.
It's hard to describe how thoroughly this turn of events crushes hopes that this election would inch Kenya towards a more robust democracy - a reminder that no matter how badly most Kenyans reject violence, those with power can inflict wanton damage at will.
He had publicly sought to reassure voters that the results of the August 8 election would not be tampered with.
Caro's sister Jedida Wanjiku said, they last talked on phone at around 7pm, when Caro Ngumbu told her she was going to have a few drinks with Mr Msando. In 2013, electronic voting machines suffered widespread malfunctions, but Odinga took his complaints to court, which dismissed them.
Kenyatta has repeatedly denied accusations leveled by the opposition that he wants to use force to rig the elections.
"There was no doubt he was tortured and murdered", said the chairperson of the country's Independent Electoral and Boundaries Commission, IEBC, Wafula Chebukati.
Some analysts question the impact of economic factors, stressing that most Kenyans still vote along ethnic lines.
U.S. ambassador Robert F Godec and British High Commissioner Nic Hailey condemned the killing and said they welcomed the government's commitment to investigate the crime, adding: "We have offered our assistance in the investigation".
