Cleo Smith's devastated mum shares adorable new photo of the four-year-old with her sister - as eerie new CCTV footage from a beach shack captures her voice the day before she vanished

The heartbroken mother of Cleo Smith has shared an adorable new photo of the four-year-old in another desperate plea for answers as eerie CCTV footage captures the little girl's voice the day before she vanished. 

The audio was captured by a CCTV camera installed inside a beach shack just 20m from the family tent Cleo mysteriously disappeared from last Saturday. 

WA Police have confirmed the voice of the missing four-year-old can be heard on the motion-sensitive camera, which also takes a wide-angled photo of anyone who enters or leaves the shack.

Officers have scrutinised copies of the CCTV footage and said on Sunday the new evidence helped place Cleo at the campground on the day before she went missing.

The camera captures audio and images from inside a box with a glass front and would not appear obvious to those passing by the shack.
