Murdered former British cavalry officer, Tristan Voorspuy, had written to friends predicting the attack just weeks before his untimely death.
Writing about the “cheap illegal firearms” he said he was “bracing for an armed walk on”.
In the letter, he described how his 24-year-old son had recently been “shot at and intimidated” by armed youths at his ranch.
“With the tourist lodge we employ 150 people and pay $200,000 (£164,000) in tax every year.
“It is a culmination of 18 years of love and investment but we are bracing ourselves for an armed walk on any day now…
“Civil wars in neighbouring countries have meant huge quantities of cheap and illegal firearms are at hand to any callow youth.
“If the Laikipia ranch owners upped and left, these people would be happy for a very short space of time as they swamped the land and destroyed every last blade of grass.
“The attitude of ‘if I do not get that last blade, somebody else will’ is paramount and sadly the paradigm that governs most overpopulated pastoral activity today.’
“Sadly Laikipia and Kenya is one small example of the greatest challenge mankind has yet faced. What chance for the wildlife and tourism yet alone ourselves in the long run.” – Tristan Voorspuy
His company, Offbeat Safaris, had recently been labelled his firm as “degraded” and “worthless” in the Kenyan press.
Since Mr Voorspuy was shot and killed, 379 herders have been arrested and two men have been charged with his murder. Local MP Mathew Lempurkel has also been accused of inciting the violence and according to police, may also face a murder charge.
