A Phoenix couple has claimed responsibility for putting two fake skeletons sitting in lawn chairs in the Colorado River.

In this frame from video provided by the La Paz Sheriffs' Office, fake skeletons are strategically placed to appear as if they were sitting together with their lawn chairs bound to large rocks in the Colorado River near the Arizona and California border.

The husband and wife approached the La Paz County Sheriff’s Office and revealed how the skeletons in their closet ended up at the bottom of the river in Parker. The pair, who may identify themselves publicly next week, came forward after seeing all the media attention surrounding the skeletons.

A man snorkelling in the river near the Arizona and California border spotted the skeletons about 40ft (12m) underwater. Believing they were actual remains, he contacted authorities. But it soon became clear to a Buckskin Fire Department diver that they were fake.
