According to Jane she told the GNR and then, at 3am, the PJ. The PJ Inspector doesn't mention speaking to anyone except Gerry, though.
The OC services manager introduced him to the missing girls parents, who looked quite tired and anguished, particularly the mother who appeared more upset and was therefore less receptive to conversation, which led the witness to converse only with the girls father.

I'm referring to this passage from Tanner's rogatory statement:
"4078 “Okay. Well tell me about that part then, how did you come to go into Gerry and Kate’s apartment?”
Reply “Well when the GNR people came, so the first lot of Police, the local Police came, erm, I spoke to them and I think that was through the translator, which was, I think she’s called Sylvie, she’s the Head of Housekeeping or something, she was doing the translating at that point. So I’d spoken to the GNR Police and then when the PJ came, they came to get me to talk to them to say, to say what, what I’d seen. And then I can remember the same GNR person saying to me later on in the night ‘Oh have you spoken to the PJ’ and I had by that stage, so”.
4078 “So when you went into Gerry and Kate’s apartment who else was there?”
Reply “Erm, I think there was Russ, I think Russell came with me and there was Sylvie who was the translator. I can’t remember which, there was some, there was a PJ chap was sitting on the, by the table. And there was Gerry who was standing by the, the bedroom door”.
4078 “And how was Gerry at that point?”
Reply “Oh he was just, well obviously, obviously distraught. And I think it was quite hard for me to be saying at that, you know, looking in his face and to be explaining what I’d seen, at that point was quite hard because, you know, Gerry was obviously standing there, I don’t know whether, and you sort of think ‘Oh God, here’s me, if I’d tried to stop them this wouldn’t have happened’ sort of thing. So I think I did feel sort of a bit obviously guilty at that stage even though I didn’t know whether it was anything, but obviously you think ‘Oh bloody hell, what if I’, not stopped it happened potentially”.
She spoke to Gerry because Gerry was there with the police. She didn't seek him out.
