THE man seen driving a red car which Jayde entered by her own free will was assisting police as part of the investigation, Darling Downs District Inspector Dave Isherwood said.
He said police had confirmed Jayde willingly entered a red car outside Lockyer district High School, and police had spoken with the male driver.
"That person was located (Tuesday) night and was interviewed or spoken to by police," he said.
"He subsequently has given a version of events (and) as a result of that version of events, we are now conducting further inquiries into the missing person.
"I think there's no doubt that she got into the car of her own free will."
An investigation centre has been established at the Laidley Police Station.
"At this point in time the family are in a terrible state, as you'd imagine, the father is distraught having lost his wife some years ago to cancer which is quite distressing," he said.
"Now he's got his daughter missing, he's a sole parent so the bottom line is he is very distressed by this.
"It's totally out of character and they're a very close knit family (and) it's totally out of character for this to occur.
"At this point in time there's no evidence to suggest she would be in that area (around Walloon) but we can't discount anything at this stage."
Insp. Isherwood said Jayde's father discovered she was missing when he went to pick her up from her Friday night shift at the Gatton McDonald's about 9pm.
He said police were looking at the circumstances as to why staff at the restaurant did not raise the alarm earlier with authorities.
He urged the public to discount unconfirmed reports on social media about the girl's character and circumstances around her disappearance.
"I can say from the outset can we disregard any of that stuff - it's not helpful to any of the family who read it and it's certainly not helpful to the police who are doing the investigation because most of it, to put it mildly, (is) absolutely garbage," Insp. Isherwood said.
"There is no suggestion at all that this girl is promiscuous, that this girl is anything but a decent kid that's tried to have a go at life."
He urged people to report any information to Crime Stoppers on 1800 333 000.
