As shown in our unseen pictures below, things don't look good for Billy (Perry Fenwick) as he doesn't have anyone to back up his alibi for the night of the murder.
Billy also admits to having an argument with Heather the week before she died, which adds to the suspicion surrounding him.
Although Billy insists that he would never harm Heather, the situation looks increasingly bleak. Will anyone come forward to clear Billy's name?
EastEnders airs these scenes tonight at 8pm on BBC One.
