Three young girls reported missing from a city in the US state of Washington have been found dead and their father is suspected of their murders.

The Wenatchee Police Department reported that Paityn Decker (9), Evelyn Decker (8), and Olivia Decker (5) were discovered deceased close to the Rock Island Campground, situated to the west of Leavenworth, on Monday.

The father, 32-year-old Travis Decker, is still missing and wanted for first-degree murder and kidnapping charges.

The girls were last seen on Friday, May 30 with Travis for a scheduled visitation.

They were reported missing later that evening by their mother.

A Missing Person Alert was issued on Saturday by Washington State Patrol.

At the time of their disappearance, the girls were thought to be residing in a white 2017 GMC Sierra pickup truck, bearing the Washington license plate D20165C.

The pickup was found unoccupied near the campground where the girls’ bodies were discovered.

Decker is 5 feet 8 inches tall, 190 pounds with black hair and brown eyes.

He was last seen wearing a light-colored shirt and dark shorts.

Wenatchee police say it’s unknown if Decker is armed but he is a military veteran with extensive training.

Anyone with information is asked to call 911.
