It is 19 September 2018, 27-year-old Joseph Irungu, a dashing young man well known in Nairobi's party circles, a former security agent who worked in Dubai and has also been a lookout for prominent politicians, is an unrepentant playboy.
He calls himself 'Jowie' and that is how he is known in the circles that matter. He is engaged to a popular TV presenter, Jacque Maribe, but has long had a parallel affair with a businesswoman from a wealthy family in the capital, Monica Kimani.
That evening, Jowie takes his girlfriend's car and drives to Monica's flat, the lover.
But it is not an evening like any other. There is no clandestine night to be consummated, no burning a bed to the rhythm of R&B music and Johnnie Walker. Monica has decided to break off that 'sick' relationship.
Jowie is out of it, perhaps demanding better treatment, probably a severance package. He beats her, then rams her with a series of stab wounds, disfiguring her and leaving her in a pool of blood.
She cleans herself up, washes up and disappears into thin air in the ever-busy residential district of Kilimani.
It will take Kenyan investigators a year to trace him and indict him, along with his now ex-girlfriend, who is meanwhile forced to give up her career in television.
He was indicted almost immediately, but it will take Kenyan investigators 16 months to charge him, along with his now ex-girlfriend, who is meanwhile forced to give up her career in television.
The trial of Jowie and Jacque had, perhaps, its epilogue yesterday, with an exemplary sentence for the most famous case of feminicide ever in the country: Joseph Irungu was sentenced to death. His ex-girlfriend Jacque was acquitted and she is not short of job offers, even important ones.
According to the judge of the Nairobi High Court, a woman named Grace Nzioka, the brutal murder of Monica Kimani was deliberate, studied and premeditated, as well as brutal. 
'This was not an act of defence or provocation, but a planned, intended and executed cold-blooded murder,' the judge ruled, justifying the conviction.
In reality, Jowie will never be executed. Despite being among the 22 countries in the world that have not yet abolished the death penalty, in fact no executions have taken place in Kenya for more than 30 years, and even the most recent ones refer to court-martial convictions.
According to the Kenyan Human Rights Commission, there are currently still 600 death row inmates in the country's prisons who are awaiting the death penalty but know that they are in fact serving a life sentence in harsher conditions.
The same thing will probably happen to Jowie. His sentence, more than a sentence that goes against today's morals and the values that so many years of battles for human rights have achieved and inculcated and that so many now question, appears to be a warning in a country that seems to increasingly imitate the bad habits of western man and where feminicides are disturbingly on the rise, just as fortunately the awareness of the female gender and consequently the complaints and desire of women to make their voices heard is growing.
Surely the echo of this heinous murder and its media prominence has stirred some consciences, even though there are dozens of women whose killers are still unknown in the past year.
