I am not really accusing anyone, but I think something's gone wrong with the clue's.

Rosalind Harker. 
She was his blind, ex-girlfriend yet she managed to describe him. She said he was just under 6 feet tall. How does she know that? 

She also described him as having short straight hair. I understand that she could of felt his hair but...

Everyone who knows/has worker/has had a relationship with RJ has ended up dead or has lied because they are obsessed with him. Rosalind is alive. But also she is blind, it would be easy to kill her.

He just left her... not even a goodbye. Why? Maybe he loved her but didn't want her to get hurt. 

He used the alias 'Roy Tagliaferro' so what if it was just a different guy who fitted the description? 

But then there's the smiley face of her wall, why draw it if she isn't dead and she's blind? She won't know it's there? Is it just there so people know she maybe had a relationship with him?

But she still doesn't know she was in a relationship with a serial killer. No one has told her yet. Why?

She was made to feel Timothy Carter's face and said she had never met him. So that rules him out. But wait, what if he wore a mask? But TC is dead so why are the murder's still going on? What if he really was TC and he was training other people to kill flawlessly?
