Authorities have returned to the rugged wilderness area where the bodies of three young sisters were found in June.
For nearly three months, federal, state and local personnel have searched the mountainous, wooded areas near Leavenworth, Washington, looking for Travis Decker. The military veteran is accused of suffocating his three daughters — 9-year-old Paityn, 8-year-old Evelyn and 5-year-old Olivia.
"We don't get frustrated though, we're not gonna give up, we understand this could take years," said Mike Morrison, Chelan County Sheriff.
On Monday, the FBI said it was leading search teams back to the location where the girls' bodies and Decker's vehicle were found on June 2 — near the Rock Island Campground in the Okanogan-Wenatchee National Forest, CBS News reported.
Authorities say the move was not because of any new break in the case.
"Currently, we have no evidence that Travis Decker is alive or dead," said Peter Orth, FBI Supervisory Senior Resident Agent.
The multi-agency team conducted a grid search across a quarter-mile radius surrounding the campground.
"You can't be too thorough in a search like this. It is such incredibly dense vegetation that anybody who walks down one of these trails could walk 10 meters off the trail and no one would ever know they're there," Orth said.
The U.S. Marshals Service is offering a $20,000 reward for information leading to Decker's capture.
"This is a beautiful area in which a heinous crime occurred. We are here to seek justice for Paityn, Evelyn, and Olivia," Orth said.
