The society claimed the vendor later disowned the sale agreement and moved to court in a bid to repossess the land.
The case has dragged on in court for decades and the delay has proved disastrous.
As the case stalled, officials and members of the society were reported dying and disappearing mysteriously.
At least six officials were killed and four other members were reported to have disappeared in unclear circumstances.
Among the dead officials were company secretary David Gitau, 46, and Beth Wachie, who were shot multiple times by unknown people in Pipeline, Nakuru. The deaths in 2017 were linked to the land dispute.
Wellington Oduor, the treasurer of the group, was gunned down outside his house by unknown men in November 2016.
Others who died were Collins Ochieng, who was a secretary, Tom Theuri and Paul Njogu.
Hujasikia story za Mboi-Kamiti? A land buying company sometimes back where watu walichezwa mbaya. But in turn, most directors were murdered in cold blood. Ilikuwa huko Kiambu
Following closely. But honestly what do you expect ukikula pesa ya mbaya. These land goons atakulq pesa yako na aranderande mtaani like hakuna kitu utamfanyia. Siwezi waonea huruma. Alot of kenyans have lost alot of money due to shoddy real estate deals. And they are all over.
Not talking on this case. Am talking in general. Most of the victims are conmen. Kuna jamaa hapo Njiru some rastaman called Baba Sam…guy alikula pesa ya msee after kumuuzia shamba ya kirima. Nasikia jamaa alikatwa katwa kama mboga mbele ya gate yake. Hata wife yake hangemjua… nguo tu na viatu ndio zilimtambulisha
