Police seek information on cars from CCTV footage in missing girl case

Inspector Craig Fox said they wanted to speak to anyone who was a potential witness.

"We want to speak to those drivers because we need to see firstly if they saw anything, and even if they didn't, it's to assist us in our investigation.

The CCTV footage shows two silver sedans, one of which police say is likely to be a Holden Commodore with a spoiler, and a van similar to a Honda Odyssey.

Inspector Fox said police have spoken to some drivers already.

"For whatever reason, they weren't aware that that was their vehicle they were driving on Henry Street on the night of April 30," he said.

"They've also said they didn't realise we wanted them to come forward because they didn't have anything to tell us; that in itself is what we're after.

"We actually want to discount you from any investigation from any potential witness so we can move on with other aspects of the investigation."

Inspector Fox said the images, while blurry, might be enough to prompt someone's memory.

"They may know already that they are driving their vehicle and for some reason, just haven't. It's all part of our investigation," he said.

Inspector Fox said the longer the investigation continued, the slimmer the chances of a successful outcome.

"But we have to maintain that as our focus to find a missing person alive," he said.

"If Shyanne is still alive and for whatever reason she's too scared to come forward, there's a strong chance that she's still in the state."

Shyanne has not been seen or heard from since Sunday, April 30, and police have serious concerns for her welfare.

She is described as being about 160cm tall with a slim build and blonde hair.

She was last seen wearing bike shorts and a cream hoodie, with dark writing across the chest and shoulder.

Anyone with information that will assist the investigation should contact police on 131 444 or Crime Stoppers Tasmania - information can be provided anonymously.
