Suddenly this thought struck me: was it FAKED DEATH ???
What if Vincent had put himself in some really bad situation, like owe the VERY wrong people lots of money or something to that effect, and so he and Angelika put together a plan that Vincent should "accidentally/drown/disappear" never to be found but eventually be declared dead.
Angelika should soon go back to Latvia in Europe bc the love of her life had died, and back there in Latvia is Vincent waiting for her with all the great money, which is worth a LOT more in an eastern European country like Latvia.
They had, after all, already planed to marry at the Latvia seashore right?
And a scenario like this would answer several mysterious questions in this case:
1.What motive would Angelika have to murder Vincent?
answer: she didn't have a motive, bc she didn't kill him and he did not drown/die.
2.How come she seem to not grief at all? in the contrary she seem happy go lucky in many of the photos in her Facebook taken and posted AFTER Vincent's accident?
answer:she never killed him it was all a sneaky plan to make him look dead + some common financial gain, and she was now just longing and looking forward to meet him back in her home country, and there living together happily ever after.
3.Angelika's serious inconsistencies when explaining what and how the accident happened?
answer: Those inconsistencies occurred simply bc the accident/murder never happened, and it is extremely difficult to "remember" a course of events that never happened, especially the details.
I know it is a long shot, but then again... maybe not :thinking:
