First, some context and background. You will already have read the state media reports and articles implicating the white farmer's organisation, the Commercial Farmers Union, in the crash that killed Mrs Tsvangirai.
Then there was an attempt to muddy the waters through the release of anonymous information alleging that one of the drivers of the two trucks involved in this story is employed by Saviour Kasukuwere, the Minister of Youth (ZANU PF).
This has turned out to be untrue.
But so far, the ZANU PF government is determined to pursue its allegations. That is why we have former information minister Jonathan Moyo, Ceaser Zvayi at the state-owned Herald and others wondering out loud about this discrepancy and that inconsistency.
The case, if we can call it that, has the following ingredients.
It has now emerged that the truck that hit the Prime Minister's car actually belongs to a logistics company, JSI, which appears to have been subcontracted to deliver medicines to HIV/Aids patients across Zimbabwe.
This would not be so bad by itself, but the said JSI is headquartered at Agriculture House in Marlborough, here in Harare. This building is, in turn, the Headquarters of the Commercial Farmers Union of Zimbabwe, a white farmers' association.
So, the Herald a couple of days back emblazoned a headline that said, "CFU Implicated In Tsvangirai Crash." I would venture to call this story an act of incitement.
Still, it gets curioser and curioser. JSI themselves have also told the Standard newspaper that the death driver was not their regular driver and they were trying to investigate how he ended up behind the wheel.
The Administrator who books drivers in and out at JSI has apparently been suspended. Internal investigations at JSI are said to be underway.
It is curious, also, is it not, that while the government is girding up its loins to happily go on a wild goose chase, they are at the same time, putting together a delegation to go and beg for donor aid from European countries.
Quite clearly, the MDC-PF government can not be trusted to conduct a sincere investigation of this matter. They have already donned their witchhunt outfits and should be allowed nowhere this sensitive matter.
Conspiracy theories should be quashed straight away by the institution of that international investigation that people are calling for.
Otherwise we will be left with varying stories and suspicions. Already, quite a number of people have concluded that this was the work of the CIA. Ironically, the British Foreign Office saved Mugabe's hide on this one.
By announcing hours after the accident that it was "genuine", they removed all suspicion from Mugabe. But Mugabe is now turning around and going after them and the Americans and the white farmers in Zimbabwe.
That's gratitude for you.
