The guy at the funeral with the dog isn't the 'new one' (if there is a new one?). A quick search through her Facebook showed pictures of them from Sep 2016.
I think the confusion with whose dog it is might partly be due to the fact that it was the bf's before they got together but then it started living with Toyah. Maybe his living arrangements changed and he wasn't able to keep it at his residence but it was still technically his dog? Toyah clearly loved that dog.
I keep thinking...did she work at the markets she was at? Often young, attractive girls, whose work involves interacting with the public, get admirers that genuinely believe there is a close relationship with themself and the person serving them. I've had it happen to me numerous times, it is frightening. They think there is interest there, when really, it is our job to be nice.
Such a sad thing to happen. She had her whole life ahead of her. I really thought (hoped?) that there would be an arrest by now.
