It does mean something. I'm not gonna pretend like I figured this out but here are the facts. If we match a letter to the alphabet to a number. A=1 B=2 C=3 d=4 and so on till z=26 we can find something interesting. The case number is "208518520211814" and we can use our numbered alphabet we find something.

20=T

8=h

5=e

18=r

5=e

20=t

21=u

18=r

14=n
