A tragedy is unfolding in Washington State.

Days after the bodies of Travis Decker’s three daughters Paityn, 9, Evelyn, 8, and Olivia, 5, were discovered in Chelan County near his truck, police are searching for the 32-year-old.

“A Chelan County deputy located Decker’s vehicle near the Rock Island Campground accessed by Icicle Road. The vehicle was unoccupied,” Wenatchee police said in a June 3 statement. “Additional law enforcement officers responded and searched the immediate area. During the search, the bodies of the three missing girls were discovered.”

“Decker is currently wanted for 3 counts of Murder 1st degree and Kidnapping 1st degree,” the statement continued. “Decker is a former Military with extensive training. It is unknown whether Decker is currently armed, but he may pose a significant risk, if approached.”

The girls’ mother had filed a civil complaint May 30, saying her daughters had not returned after a planned visitation with their father, the Wenatchee Police Department said.
