No. That is ONE news source. There are no other news stations taking that angle and don't you think it is for good cause?
Murders are normally called as murders instantly. Did we ever hear Titus's victim may have killed herself? The ambiguity of the press/police here is for good reason - obviously there is reason to be unsure, whatever the outcome may be.
It's no coincidence that those actually in the industry suspected murder/suicide quickly due to having knowledge of prior events of the past year or so. If one actually wanted to be disrespectful, there is loads of true things that certain people could post, the fact that they are not being posted - is respect. Which is good...
Also, Romano posted "rumour" - in all caps - to start thread title. That alone should have indicated to people it was, in fact, a rumour. And who takes a message board thread as the gospel? I've read that Cormier died 3 times on various forums so far
