's mum Debbie has hit out at TV detective Mark Williams-Thomas, accusing him of using the death of Jay to gain publicity.
The 19-year-old went missing on June 17 after attending a music festival in Tenerife.
He left the event with two other men to go to their Airbnb in the northwest of the Spanish island.
Jay tragically died while trying to make a long 10-hour journey on foot back to his accommodation. He fell while walking through the treacherous Teno Rural Park.
Now, his mum has hit out at Mr Williams-Thomas , but has since refused to give any more information.
Speaking to MailOnline, Debbie said: "If he knows something I wish he would say it, otherwise people will think it's just publicity and it's not doing me any good.
"I'm still in bits here, I'm having counselling, and it doesn't get any easier, I couldn't sleep at all last night because after he posted what he did it on his social media just kicked off all the trolls again.
"Losing Jay was hard enough but then having to read what some people are writing is torture, I'm not good really and I would be lying if I said I was alright, the last few hours have just been awful.
"What he said has knocked me back a million steps, I just wish he would say what he knows or just stay out of it, we last spoke a few weeks ago briefly because I wanted to clear some things up.
"It was nothing untoward, I just wanted to refresh my brain because I couldn't remember much from the first couple of weeks as you saw what I was like, I had just lost the plot, my son was missing, and I wanted to find him."
She continued: "There was nothing really new, I just wanted to go over some things and he said if I remembered anything to give me a call and that was it, now it's all over the news again and it's really knocked me.
"I thought for a second he might have something but now I'm thinking it might just be a PR stunt as all it's done is that it's got all the bloody Tick Tockers back and they have never really stopped which is even sadder.
"I try to avoid it but then I think I will have a little look and it knocks me back because they just go over the same stuff but I'm not biting on what he's saying, I don't know why he's said what he did.
"I didn't sleep last night and I'm going through enough as it is. He's put this on his socials but he hasn't backed it up, if he knows anything then he should say.
"There's a lot of people saying "what's he got?" or "what's he found?" so that's why I'm saying if he has anything he should.
"There is only one person who really knows what happened and he's not here to tell us what happened, that's why everything is just speculation.
"I still think speaking to his friends at the time, Jay just wanted to carry on partying and he left but like I say there's only one person who knows, although I'd like to know more from the guy who was at the Airbnb."
Debbie also told of how she has not returned to work as she still struggle from the grief.
Mr Williams-Thomas has said there "had been a huge amount of misinformation" when he went to Tenerife to look into the case.
In a video, he also said he gets on with Debbie.
He added: "I was very clear from Day One this looked like a tragic accident. There were considerable issues - I haven't revealed the details of these issues - exactly why Jay left in the manner he did. Why didn't he return?
"These things I've kept to myself at this moment in time. Maybe, when the time is right, I will reveal those.
"I've got to be very careful. What I don't want to do is upset the family with any more trauma than they have already had and so it would be something I would work very closely with Debbie and the family on to reveal that information.
"Maybe the time will be right soon, but not right now."
