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.

According to the Wenatchee Police Department, nine-year-old Paityn Decker, eight-year-old Evelyn Decker, and five-year-old Olivia Decker were found dead near the Rock Island Campground 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.

When the three girls went missing, Decker was believed to be living out of a white, 2017 GMC Sierra pickup truck with 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.
