This rule deals with where a criminal homicide case can be tried in Oregon. It says that when someone is charged with causing another person's death, either the death itself or the actions that led to the death can count as the "result" of the crime. This matters because Oregon law generally lets a case be tried in the place where the result of a crime happened.
The rule also gives a practical shortcut for prosecutors. If a victim's body, or even just part of it, is found somewhere in Oregon, that fact alone is enough to show the death "resulted" in that location. This means prosecutors don't have to prove exactly where the killing took place. They can rely on where the body was found to establish that the case can be tried in that county or area.
In short, this rule makes it easier to decide which court has the right to hear a homicide case. It focuses on where the body turns up, rather than requiring proof of the exact location where the deadly act occurred.
