Each of the caches nearby named "CeCe Corpse Conundrum" are a part of the multicache "The Curious Case Of CeCe Corpse". You do not need to do the multicache to be able to find the individual caches, these can be done as standalones if you wish.
Good luck, and happy caching! (:
Permission to place these caches was given by Russell Boland, the parks officer.
