Where are the investigations into Valyrakis' death heading?

Two scenarios are being examined by the authorities as to the circumstances of the death of the former minister of PASOK, Sifi Valyrakis, who was found dead on Sunday evening (24/01).

More specifically, as stated in a report of MEGA, the element that puzzles the authorities is that the dead man was found with a head wound.

As a result, this finding makes the Coast Guard investigating the case consider two scenarios:

1. The first one wants Sifi Valyrakis for unknown reason to lose his balance in the inflatable boat he was on, falling into the water and being injured in the head by the propeller of his own boat.
2. The second scenario wants Sifi Valyrakis to be injured in the head by another boat propeller with which his own dinghy collided.Especially for the second scenario answers will give the report of experts who will examine whether the dinghy of the former minister there are traces of a collision.

It is worth noting that, Sifis Valyrakis, was missing since yesterday (24/01), at noon in the sea area of Eretria, while, on the same day, a few hours later, he was found dead on the small island of Pezonisi Eretria in the evening of the same day.
