I'm fairly sure that Life Guards at swimming pools/beaches are well trained to save lives in water. It stands to reason that they would also be well trained about the greatest hazards to life related to water. They may be well qualified to "disappear" a person's body permanently in the ocean.I would like to know of any trips out to sea, or anywhere where there is a large enough body of water, like a lake or a dam.
Look at all the bodies starting to be found at Lake Mead in the US.
Lyn's body could be weighted down somewhere
They are just not able to "disappear" her soul or her spirit or her essence. That lives on.
