Actually according to her latest story though Billie wasnt gone though because he took her to work and whats more she had to of known that from that very first day. If and i say IF Billie is not in the know then i dont see how she has told all these lies for the past two years. And no i dont think for one minute it was because she was scared of him because she actually seems the more violent one out of the pair ;(
Also personaly i dont even believe it was Shawn who killed Hailey if indeed she was killed ;( i believe Billie got in such a rage over events on the Sunday night that she just snapped ;(
It doesn't matter what she is saying now, we know he didn't take her to work because someone else did and confirmed that to LE at the time.
She was confirmed as leaving CC at 6.20, while SA was confirmed by witnesses at work between 6.00 and 6.10. So, there is absolutely no way he could have taken her to work.
