The point Steve made just before he handed the file over to Ted is significant. He said they didn’t run new officers DNA against the database for matches when Jo joined. Implying, or outright saying, the DNA was there 20 years ago and the match would have been alarming enough to raise flags.
That blows the Lakewell theory. Because being related to a solicitor isn’t an issue. Also if they were threatening her with Lakewells safety, why kill him?
It also blows Corbett, he would have been in there as a PC at that time or not at all if he hadn’t joined. His dna was removed years later when he was undercover. Also not really a red flag 🚩
Terry Boyle would not be alarming 20 years ago. Nor would a relationship to the Lavertys, Ryan’s mum,Denton, Bigglelow, Ted, Osborne or Dryden.
Hunter, if he was on police radar at that time, would be alarming. Because she failed to disclose it. But I still think she could have spun a story of family alienation to explain it all even 20 years on. There either are or aren’t birth records to show the connection. Which would be found in a background check. This implies there are no records connecting them. Easy enough to deny the relationship was known or close.
Doesn’t leave us with much. Except Hunter and that she not only didn’t disclose it but fundamentally lied about her background and identity. That’s something she couldn’t wriggle out of and would be serious.
