An aide to Kimilili politician Brian Khaemba will be laid to rest on Saturday in Malava, Kakamega county.
A requiem mass for the deceased was held on Friday ahead of burial.
Olunga is said to have been shot dead allegedly by Kimilili MP-elect Didmus Barasa on August 9, 2022.
DAP-K party, whose ticket Khaemba used to vie for Kimilili MP seat, mourned Olunga and called for justice.
"As we bid him goodbye, we pray for nothing but justice to his family and the culprit to be held liable," the Party's Twitter handle reads.
An autopsy done on Wednesday showed that Olunga was shot and killed by a pistol bullet to the head.
Barasa is currently in custody after the prosecution applied for more time to conclude investigations into the murder and allow more witnesses, including NYS and IEBC officials, to record statements.
A Tuesday court ruling saw an addition of 10 days to his time in custody.
The case will be mentioned on August 24 for the DPP Noordin Haji to confirm the status of the investigations before making the decision to charge.
According to a police report filed on the Election say, Barasa and Khaemba got into an altercation, prompting Khaemba to step out of his vehicle.
It was then that Barasa allegedly drew a pistol and aimed at Khaemba's aide Brian Olunga and shot him in the forehead killing him on the spot.
He was pronounced dead on arrival at Kimilili Subcounty hospital.
Barasa denied the claims saying he also wanted to know who killed the aide.
