Photographs have emerged from the scene of a horror Christmas Day crash that has ripped apart the lives of a young family.

Cindy Braddock, 25, Jake Day, 28, and their children, all under the age of five, were reported missing when they didn’t show up to a Christmas celebration.

They’d last been seen leaving Northam, a town in Western Australia’s Wheatbelt about 100 kilometres east of Perth, at 1am on Christmas Day.

The family was making the 200km journey back home to Kondinin to spend what was left of Christmas with Day’s mother.

“My understanding was they left Northam early so Jack could be with his mum on Christmas,” his cousin Michael Read told 7NEWS.

However, on Tuesday evening, police said the family’s maroon Land Rover had been found by another family member, 10 kilometres from the town.

“[I’m] pretty broken - not only have I lost my cousin, but one of my close friends... basically, we’re just taking one day at a time,” Read said.

Braddock and Day were both found dead inside the vehicle.

Two of the children, a five-year-old girl and a two-year-old boy, were outside the vehicle, while a two-month-old baby was still inside.

The youngest child suffered a significant head injury and is in a serious condition.

Read said the community will be devastated by the loss of the young parents.

“They were really good parents, always good to have a joke and a beer with,” he said.

“They are going to be pretty missed by everybody - not just family and friends, but the community as well.

He described his cousin as a “bubbly person” who was just “someone you could always get along with”.

As for Braddock, he said she was “overprotective of her children” who “always want mum”.

Police had organised an “urgent” search for the young family, believing they were travelling towards Kondinin.

Family members of Day or Braddock took to social media to seek answers.

“They left Northam on Xmas Eve to go home to Kondinin,” one family member posted on Facebook.

“No one has seen or heard from them since and they haven’t made it home.”
