A Senate committee has summoned controversial preacher Paul Mackenzie, Pastor Ezekiel Odero and DCI boss Mohammed Amin over the deaths in Shakahola, Kilifi.
The ad-hoc committee probing the mysterious deaths has also summoned chief government pathologist Johannsen Oduor and individual security and administration officers who were in charge at the time the deaths occurred.
Also set to appear before the panel are the Kaya elders.
They have been summoned to appear on Friday in the last public hearings by the committee that is set to release its investigation report by Thursday next week.
The committee chaired by Tana River Senator Danson Mungatana has issued the summonses through the Prisons Department to produce Mackenzie, who is currently in custody.
The state is treating Mackenzie as the main perpetrator of the deaths mainly caused by starvations allegedly due to extremist teachings by the preacher.
Mackenzie is claimed to have told his followers, including children and women, to starve themselves to death because the world was ending and they could thus swiftly meet Jesus.
“As the Senate we have done all the paperwork and delivered to the Department of Prisons to produce him tomorrow (Friday),” Mungatana said.
Mackenzie is sought to shed the light on his involvement or lack of it in the happenings at the vast Shakahola forest where hundreds of bodies have been exhumed.
The state has claimed that Makenzie could have been working in collaboration with Pastor Odero, a renowned preacher with massive following. Odero runs the New Life Prayer Center.
However, Odero has denied the claims and is currently out on bail following his arrest, detention and arraignment.
Postmortem done on the exhumed bodies revealed most of the deaths were due to starvation or strangulation.
DCI boss Amin will explain how his officers in Kilifi failed to detect and deter the mass deaths.
Amin will also delve into the status of investigation to unearth the people behind the mysterious deaths.
This will be the second time the DCI chief will be appearing before the panel to give information.
The state has been criticised for lax security and not monitoring the vast forest where the bodies were exhumed.
The panel has been investigating the mass deaths for months. It has twice sought extension of time to conclude it work.
Initially, the committee was given 90 days to do the probe and table its report in the House, but it sought 30 more days.
Last week, the House granted the committee 15 extra days to finalise the investigations and table a report. The extension lapses on Thursday next week.
Interior CS Kithure Kindiki has maintained that the state will stop at nothing to bring the perpetrators of the deaths to book.
Appearing before the committee three months ago, the CS appeared to blame security agencies for laxity after they failed to act on intelligence reports on criminal activities happening at Shahakola forest.
“If the reports were acted upon, maybe the Shakahola massacre could have been mitigated or even prevented,” the CS said.
Kindiki assured the committee that officers who slept on the job as followers of Mackenzie starved to death in Shakahola will face the law.
The CS said he also believes some officials in the Judiciary will be held responsible.
“I believe some officers from the National Police Service and even the Judiciary have a case to answer,” he said.
The CS vowed that no one will be “forgiven for trying to weaken the potential of the prosecution to win the case against Mackenzie.”
“I have told the DPP we should win this case. If we lose, then I do not know what we expect as a country,” he added.
