Mourners on Monday confronted one of Chris Msando's bosses at the City Mortuary and told him to leave.
The mourner accused James Muhati, the electoral commission's ICT director, of betraying Msando.
Muhati had arrived in the company of Independent Electoral and Boundaries Commission (IEBC) colleagues to view Msando's body.
One mourner, who claimed that Muhati was part of the problems that Msando faced at his workplace, tried to attack him but she was restrained.
Three other mourners confronted him as he ran to where IEBC commissioners and other staff were standing.
In May, Muhati was suspended for a month after he was accused of refusing to cooperate in an audit of the agency's ICT systems. The decision was reached at a plenary meeting chaired by Chairman Wafula Chebukati.
Msando was appointed acting director. Muhati was later reinstated.
A number of Msando's colleagues broke down after viewing his body. They described him as a dedicated and hardworking man.
"Why torture a poor man like that?" said one of the mourners.
His widow, Eva, was reluctant to leave her husband's body. Relatives had to persuade her to leave to allow the attendants to prepare the body to be moved to Lee Funeral Home.
