I mean they’ll do an investigation. The most likely thing is a protest/revenge killing, but there are other possibilities. One I thought of - what if someone actually wanted him killed for reasons completely unrelated to him being an insurance executive? For a hypothetical example (which I have zero evidence to believe to be true), what if the wife wanted him killed for the insurance money? Maybe he was as cruel to her as he was to his customers. Maybe the wife hires a hit man to take the guy out. That hit sure looked pretty professional. Again, I have no evidence to suspect this is true. But what if? Anyone who had a motive to have the guy killed could easily try to make it look like a protest killing. And you rarely get to that level of corporate power without having a few skeletons in the closet.
That hit sure looked pretty professional.
I am not expert, but I would be cautious with calling this a professional job.
I live in Ukraine and we’ve had a wide variety of assassinations run by the russian security services. Some where clearly much more professional than this one. Others were less professional than this one, but still organized by the russian security services (this was confirmed by subsequent investigations).
