The family of murdered IEBC official Chris Msando wants the FBI and Scotland Yard brought in to investigate the killing shortly before the August 8 General election.
On Tuesday, it also urged the government to expedite its investigation into what many people call a political assassination.
Msando was tortured, possibly to get password and other information, say the opposition and rights groups.
His body was found on July 31.
Msando was the key ICT manager for the IEBC and frequently spoke of how secure the system was.
He was found murdered on July 30.
His sister Alice Awuor told the Star on Tuesday the government should incorporate the Federal Bureau of Investigations and Scotland Yard to speed up the probe.
His mother Maria Aloo said it is now close to three months since her son was killed but no report has been given regarding investigations into his mysterious death.
The 75-year-old pleaded with the government to hasten its investigations and prosecute her son’s killers.
She said the family wants to see justice for their son.
“The government promised to unearth the mystery surrounding the death of my son, but close to three months now, nothing has happened,” Aloo said.
She said the government is not interested in pursuing the matter to its conclusion. She asked why the statewas taking too long to apprehend the perpetrators, despite earlier assurances that it would do so.
She was speaking to the Star at her home in Lifunga village in Ugenya, Siaya county on Tuesday.
She said her son’s death has left her destitute.
Aloo depended entirely on Msando.
She said memories of her slain son have given her sleepless nights.
Her son’s spirit will rest only after the family is shown those behind his murder, she said.
Msando was killed alongside 21-year-old woman, Carol Ngumbu. Their bodies were found dumped in a Kikuyu forest.
Postmorterm revealed that he was tortured and then strangled.
