Mr Odinga posted the controversial photo along with his condolence message to the former legislator's family on his verified Twiter handle.
Many followers took issue with the fact that the departed MP's body could be clearly seen, including a recognizable part of his face. Here is the NASA leader's post, that many found disturbing.
Mr Odinga's followers shared various remarks accusing the leader of being insensitive to have posted it.
In a more detailed post on his Facebook account, the NASA leader eulogised the deceased MP as a dedicated leader.
"Hon Nyenze served his constituents and the country with dedication cumulatively for decades, in various capacities as MP, Minister, and Leader of Minority in Parliament. In Hon Nyenze’s death, NASA has lost a dedicated leader.
"May God grant his loved ones comfort during this trying time," the post read in part.
However, both posts were pulled down shortly after with no replacement message.
Earlier in the day, the NASA leaders had been at the City Mortuary for a short service before families of slain supporters collected bodies for burial.
Mr Odinga, at the time, strongly dismissed a call from the United States to withdraw the swearing-in mission scheduled for Jamhuri day.
