The family of missing teenager Nida Ul-Naseer says she was angry about not being able to go to university before she disappeared.
In a news conference today, they revealed she was crying and shouting shortly before she left her home in Newport.
She went missing on the 28th of December and despite intensive searches and investigations there's been no trace of her since.
Today, detectives said it 'really is a mystery'.
