Is the first Zombie Lee kills during his rampage Molly's sister?

I'm replaying the game again and decided to view all tapes and get the molly conversation in which we see the picture of he sister.
Later on after Lee is bit and picks up the glass shard, he kills a unique model zombie girl. They look very similar, has it been proven to be her since I see no other pages talking or any other reddits mention this zombie girl

I know the hair is different but the photo could be old, the shirt is the same and the fact the character model is only seen here so I think it might be her
