What I would include don't matter a rats ass. It's how the law construes it that is important hence the caveat in my earlier post: I would suggest finding out precisley what the law means by corroborating evidence before saddling up.
What is corroboration in criminal law?
Corroborate. To support or enhance the believability of a fact or assertion by the presentation of additional information that confirms the truthfulness of the item. The testimony of a witness is corroborated if subsequent evidence, such as a coroner's report or the testimony of other witnesses, substantiates it.
Corroborating evidence (or corroboration) is evidence that tends to support a proposition that is already supported by some initial evidence, therefore confirming the proposition. For example, W, a witness, testifies that she saw X drive his automobile into a green car.
OK corroborating evidence of a cadaver being in the apartment -
1. a confession of a person handling the cadaver.
2. A witness seeing a cadaver in the room.
3. A witness testifying seeing a cadaver being taken into the apartment.
4. A witness testifying seeing a cadaver being taken out of the apartment.
5. A DNA sample of someone who should not be in the apartment. (DNA not matching any known visitor or occupant)
