Welcome.
Exactly, no wonder how he could get away with it. In fact is very easy, there are hardly ever people in the streets late at night, let alone at early mornings on those very coldy days. Rivers are everywhere throughout France. The possible dumping of the body on the river seems plausible. But is very weird that it hasn't floated back again yet. Even with branches below the water. With the water movement, something should've already come up.
The Prosecutor said that unfortunately it happens that bodies never turn up. For various reasons, among them the catfish in the river Doubs.
I'm still not sure if Zepeda planned this part of his crime, or if he simply got lucky. It was winter. In the middle of the night. Somewhere in an area with vast forests. No lights. Bumpy roads, perhaps the road near the river is of a slightly better quality. I know I would not want to drive there at night, and perhaps not even during daytime.
They say that the place where the victim is left, dumped, hidden, tells you something about the murderer, namely that this place has a special meaning for him. ( I wondered about that. What would
I do in the unlikely case that i had to hide a body? and I could not come up with one spot that wasn't known to me for a reason.) Except in this case, Zepeda had only arrived a few days before. He had no connection to the area, other than what he may have researched on-line.
Nowhere I have read that Zepeda was particularly at ease in the woods at night. Some people are. But AFAIK no one has mentioned this about him.
If a person had lived there all his life and hiked the area, it would be far more likely that they knew the remote corners, crevasses, the characteristics of the river and the perfect hiding place.
Yet Zepeda somehow managed this in less than two nights.
I don't know but I have the feeling that something is missing. If Narumi's remains went into the river, there is a chance that they would have been found before Zepeda returned to Chile. He must have been aware of that risk, but he does not hurry. So how did he ensure that the remains would not be found?
