An insensible hexagon

Question

The puzzle is (almost) self-contained in the grid above. You can "move" from a tile of the grid to another if they share at least a vertex. After the maze is complete six things will clue to the solution which is an English phrase composed of four words of lenght 3,7, 7 and 10 letters.

EDIT: I've updated the picture due to an error (call it a typo). This edit does not impact the method that should be used to find the solution, the solution itself changes only a little bit. Pleas don't look at the edit history if you want to solve this puzzle from scratch, otherwise it will be too simple.

Answer 1

Building on msh210's excellent answer, here's my conclusion:

The only remaining letters in the maze that aren't Mike Shinoda's tweet or strings of a-z seem to be "rip CCB" (they're near '...true. An...'). And since we already know the riddle is about Chester Bennington's death (and was posted on the 3rd anniversary of it), the fitting phrase for the 3,7,7,10 grid that the riddle seems to indicate would be:

RIP Chester Charles Bennington

Answer 2

The path is

which spells out

"Shocked and heartbroken, but it's true. An official statement will come out as soon as we have one." (except in lowercase and with neither punctuation nor spaces). That's Mike Shinoda's tweet about Chester Bennington's death. The path goes from "LK" in to a park because both men were members of the music band Linkin Park. The shape the path takes is the Linkin Park logo. The title of this puzzle may be a reference to the death as insensible (in the sense of "meaningless") or to the Linkin Park song "Numb" (which means insensible in its more usual meaning), besides of course referring to what appears to be a meaningless grid of letters. The leftover letters (unused in the path) go through the alphabet repeatedly and connectedly except for two stray letters C and B (the only capital letters in the grid) for Bennington's initials. As for "the solution which is an English phrase composed of three words of lenght 3,7 and 10 letters" (sic), I really don't know, but can guess that it's "bye, Chester Bennington".
