Over in Australia, NSW police have laid out a timeline relating to the disappearance of Sydney couple, Jesse Baird and Luke Davies.

Police have accused 28-year-old constable, Beau Lamarre-Condon, of murdering them in Baird's home, then making multiple trips to a rural property.

It's now being scoured for the missing pair.

Australian correspondent Murray Olds says police have had to widen their search over the past few days.
