To clarify, in my last post, I was speaking of the Causeway. I forgot that detail!
Below is
@Spectrix's image of Crawford Pond from p.2, for reference.
From this image it appears the distance to the mainland from the island is fairly similar at the Campgound and Causeway. So maybe both are a ~15 minute swim?
That said, I'd presume the Causeway access / exit would be preferable to a perp fleeing the island because it is more obscured than the Camp.
... but if the crime did not occur on the island or involved a watercraft and not swimming, then this sleuthing is moot.
