Answer: C.) use the evidence to identify links which will eventually help reconstruct how the person died, that is, identify links in such a way that it will stand up in court.
When it comes to evidence collection, especially in the room where a corpse was found, the evidence around the room can give the investigators clues on how the person died. This is especially important when investigating a crime where no witnesses are available.
The investigators then have a chance to find out the story of how the victim died by the evidence around the room such as blood spatter, messed up things, deadly or possible weapons, etc. By having learned about the different evidence collected, the investigators may use the evidence found in court.
