The Gatundu clinic had eight beds, a small maternity room, and a medicine shelf secured with two padlocks.
The M-27 cylinder stood behind a storage room. Its label looked new. The serial had been cut into the metal years earlier.
Inspector Ruth arrived with a standards officer, a government clinical engineer, and Malik as a defence observer under an agreement between the parties.
Wanjiku was not allowed to attend.
Clinic nurse Susan Wairimu said the supplier had called three times, demanding an exchange before inspection.
“They named the batch,” she said.
“What did you tell them?” Ruth asked.
“That the cylinder had already been used.”
“And their response?”
“They said, ‘Then do not connect it to a machine again.’”
The caller used a prepaid number.
The cylinder was sealed and transported to an accredited laboratory. Nobody opened it at the clinic.
The preliminary report found that the contents did not match the certification for medical oxygen. Purity and pressure were unreliable. The laboratory did not claim the cylinder alone had killed any particular patient. It stated that the unit was unfit for medical use.
“For a patient,” Susan said, “that means the air does not arrive.”
The expert agreed.
Serial history showed the cylinder had been purchased four years earlier, entered the M-27 batch, returned after a complaint, recorded as destroyed, and delivered again under a new label through Kibo Technical Services.
Kibo was Kelvin’s company.
The physical object connected procurement records to something dangerous in the real world.
Ruth still refused to announce a criminal network based on one cylinder.
She requested invoices, ownership forms, delivery records, and proof of who authorised reuse.
County procurement officer Miriam Chebet said Rift Gas won the tender through prequalification. Northline supplied some cylinders. Kibo inspected equipment.
“Why were three companies with connected owners involved?” Ruth asked.
The forms had listed nominees rather than Kelvin.
Miriam produced the complaint file. Letters from nurses and biomedical technicians were attached.
A note on top read:
**Closed after joint technical review by supplier and Mwangaza Medical Centre consultant, Dr S. Gichuru.**
Gichuru had no county engineering role.
Jonah had introduced him as an industry expert.
His signature appeared beneath the closure.
When the report became public, Kelvin told television viewers that one cylinder could not prove a wider scheme.
He was right about that much.
One cylinder did not prove Jonah’s murder.
It proved the “technical misunderstanding” contained a real safety failure.
And somebody had tried to remove it before police arrived.
The seizure also created a new problem. Gatundu still had a child who needed oxygen, and the supplier had not delivered a replacement.
Faith and the county emergency office arranged a safe cylinder from another facility.
Wanjiku insisted the investigation create a replacement protocol.
“A clinic must not be punished for reporting evidence.”
Malik produced a one-page checklist for smaller facilities:
Photograph serials on arrival.
Match seals to delivery notes.
Record pressure and regulator checks.
Give every complaint a number.
Do not release a cylinder without replacement notification.
Describe what staff observed; do not make technical claims they cannot prove.
The pilot programme found another repeated serial before the cylinder reached a patient.
Kelvin called the programme panic.
Susan answered on county radio:
“Panic is losing air and having nobody believe the report. Checking a serial is work.”
For once, the public discussion was led by a clinic nurse rather than a famous doctor or company family.
The laboratory’s final certificate stated that the M-27 unit was not suitable for medical use.
The truth was technical, limited, and powerful.
The cylinder did not solve the murder.
It made the procurement lie impossible to dismiss.
The concluding observations of chapter 8 established clear procedural direction for all subsequent administrative actions.
