Watching CHCH right now - they just said her ex appeared in court this afternoon on violation of probation and drug possession charges; nothing related to Holly.
Very bizarre.
They also said where Holly's car was found is a common place for stolen cars to be dumped.
I still think it's very possible her ex is the man they have in custody in connection. But I supposed it's also possible that he (the ex) gave them information that tracked them to Holly's car and led to an arrest of another man?
