They claim that the act was committed by a group of people who want to revive the banned Mungiki sect, who also want to control property that was acquired by the group.
Though only seven bodies were exhumed from a mass grave discovered in an abandoned quarry in the area, they say more than 30 people have been reported missing.
One of those who went to identify the bodies at the City Mortuary and spoke on condition of anonymity due to fear said it was purely rivalry between the Mungiki and former members.
He says the rivalry escalated on May 6 after four guards were slashed to death on a disputed piece of land in Ngara, Nairobi.
The guards were killed on the piece of land that has had a long-standing dispute between a group of mechanics and a city mosque.
“Those were our members and they were killed because they were not supporting this group,” he argued.
He claims those who committed the crime still attend a church in Kitengela led by former Mungiki leader Maina Njenga. Njenga has since denounced the sect.
“We know them…they are about six and are still free. They are normally wearing black suits,” the visibly bitter man said.
After a few minutes he added, “They want to force our pastor (Maina Njenga) to allow us go back to our normal ways of extorting money. They are pressurising him to do that.”
“He has since said that Mungiki is no more and police should come in and help. If the Government fails to act fast, these people will go out of control.”
He says the Government should act fast to contain the group which now wears black, red, white and green suits which reflect the flag that was used by the group.
“This is what was used to be our flag… it means that black people in one nation shall pour blood of a black person in search of peace,” he explained.
“We used to wear hats with those colours but they want to change because people and police already know that.”
Those who went to look for their friends at the City Mortuary were all enveloped with fear saying, “We don’t know what will happen. Maybe they are here to monitor us, please don’t even take my photo.”
“Police should arrest these people…those who killed them were in black suits.”
