Police appear a step closer to solving the murder of Logan schoolgirl Tiahleigh Palmer after seizing a car linked to her disappearance.

But they say the owner of the vehicle is not a suspect.

The 12-year-old was last seen alive on October 30 when she was dropped off at Marsden State High School, in Brisbane’s south.

Her remains were located on the banks of the Pimpama River a week later.

Police on Tuesday renewed their appeal for information, asking anyone who saw a blue-coloured Ford XR6 on a road near the Pimpama River last October to come forward.

The Ford XR6 has been seized and is being forensically examined.

Detective Inspector Mark White ruled out the owner of the vehicle being a suspect.

Det Insp White said there were at least 20 officers working on the high-profile case on a day-to-day basis.

He reiterated there was a $250,000 reward for information leading to the successful prosecution of those responsible, which includes an indemnity but not for the principle offender.

“We have conducted numerous enquiries, different lines of enquires, this (asking if anyone saw the car) is just one those enquiries,” he told reporters.

He said there had been a number of people identified as persons of interest.
