I've also been wondering about TK's finances. He is now 36yo and has done a course in construction. He seems to be currently unemployed and got out of prison in June 2021. We have been told that he's never had a driving licence in his life (and still doesn't) and was it stated that his car was not registered as it was seen without number plates in his yard? Perhaps that's why he mainly drove at night and never thought LE would find out where he lived.
Having said that, has he ever worked since he left school? <modsnip> So far nobody has come forward to say that they ever worked with him. He states on FB that he worked 11 or 12 hour shifts but IMO that is probably his fantasy.
Does TK have a Psychiatric condition that stops him from working? Does he receive the Disability Support Pension?

So, IMO, the money he has recently been spending on dolls and to pay for his car may have been inherited from his grandmother - probably cash from her bank account. Perhaps her doll collection was inherited by his aunt at first and she gave it to TK as she knew he was interested in it. However, I read he began his FB posts at least by 2013 so perhaps he shared the house with his grandmother then, had access to her dolls and has added to the collection by buying more when he could afford one at Toyworld. He seems to live a modest life. I think the comment by a neighbour that he had seen ten or twelve dolls in their boxes in his car and that he might have just collected them from the post office, is possibly an assumption as he did not expect to see them in boxes.
