Tragedy struck Kabutie village after a suspended Nandi county government official on Monday committed suicide.
Shadrack Biwott, 42, drank poison after he was asked to stay at home pending an audit investigation.
He worked at the medical engineering maintenance department of the Kapsabet Referral Hospital.
His death brings to two, the number of officials who have taken own lives following the probe ordered by Governor Stephen Sang.
David Kemboi hanged himself a month ago at his house on grounds some of his seniors forged his signature to steal money from the county.
The two come from the same village.
Biwott was among 1,000 county casual workers laid off by governor Stephen Sang in August.

Police said Biwott left a suicide note saying he was unable to carter for his family after he was suspended by the county government.
"He took a poisonous chemical and we are investigating the incident," said a senior police officer.
The worker had complained to colleagues that he had not been paid for eight months and his efforts to see the governor were futile.
Area police boss Peter Wambani said Kemboi's case was still in under probe.
Hundreds of the suspended workers have protested that they are suffering yet their jobs are already being given to others.
