Victor Sang was among recruits training at the Recruits Training School in Kamagut when he collapsed during an intense drill.
His family says they were later informed that he fainted and died after suffering dehydration, a claim that has raised painful questions.
Speaking on behalf of the family, Victor’s uncle, Isaac Lang’at Koros, said the young man was healthy when he reported for training and had shown no signs of illness before his death.
He added that the family was briefly allowed to view the body at Moi Teaching and Referral Hospital, but only the upper part was visible, deepening their anxiety.
In a statement, the Kenya Defence Forces said the recruits developed medical complications during a routine endurance exercise and were given first aid before being rushed to hospital for further care.
The military said the next of kin were informed immediately and assured of support.
A post-mortem examination is expected to provide clarity on what caused Victor’s death. It will be conducted in the presence of family members and KDF officials.
Mr Koros said the family would be satisfied with the outcome of the post-mortem examination, adding that the KDF had assured them it would cover all medical bills and burial expenses.
The burial is planned at Kiribwet village in Emurua Dikirr.
As the family prepares to lay their son to rest, they say closure will only come when the full truth is known.
The incident has renewed public concern about the welfare of recruits during military training in Kenya.
