I doubt there was too... but I'd say she was probably involved...
You keep saying that, based on what, false statements by people who wanted to be involved in the case, the lead guy wanting to spread the blame, the lack of any evidence, afaik dna being found on a knife, in a flat she used, that wasn't the murder knife?
IF you live with someone, leave, someone murders the person you live with, and they put you in jail because a knife there, that wasn't the murder weapon, had your DNA on it, and there was literally no evidence in any way linking you to the murder, you'd be fine with people saying you were probably involved?
The case was a joke, she may have been involved, she probably wasn't, there is no proof she was involved at all afaik.
From what I remember a lot of people assumed her guilt because of the way she behaved in court, but in another country, accused of doing something you didn't, someone you knew semi well being murdered and the potential for being put in jail and your entire life ruined, just as many people would basically act like they were in shock and shut down as would freak out and cry like mental cases.
