OMG This is a perfect time to do some solving:

Rachie is alive but is hiding from Big R. Big R is a murderer, And in my theory Big R is also Rachie's family member. <<<<<<<<<<< First Theory

Second Theory

One of the Liars are Big R. A Few Of Them (Haley) seemed like they weren't affected by Rachie's death, They kept yelling "SHE'S DEAD!!".

Third Theory

The Unknown Person is Haley.
