OK...rumor in Cotui is this was a killing for hire.
Here's the true story behind all this. The Dutchman fell in love with a Dominican woman from Cotui...You know one of those who moved to Europe to work in the trade. So he moved to Cotui with her and proceeded to spend pretty much all his fortune on her (bought her a huge house, brand new high end SUV's, etc). Once he's almost broke she dumped him...actually moved him to this house where he was killed, while she and her driver (whom everyone around town knows is sleeping with her) enjoy this poor guy's fortune. This is all fact. I know this because I've actually met some of the involved parties and know some of their relatives.
Now the RUMOR around town is that the wife hired these guys (which weren't nice guys) and moved them to the lower level of the house (below where the Dutchman lived). She then pays off the cops to go in and execute the Dutchman with the pretext that they were there to arrest these bad guys who lived downstairs and that he just got caught up in the cross fire. How much truth there is on that whole scenario I'm not sure, but having met this woman before....well...Not sure if this Pichardo's MC from above.
Bottom line is she now has all of his money and I don't see this investigation going too far as the "shooting exchange" involved cops.
