Travis Decker, 32, is wanted for allegedly killing his three daughters – Paityn, 9; Evelyn, 8; and Olivia, 5 – after their bodies were found in a wooded area approximately 30 miles from Rock Island Campground, according to the Chelan County Sheriff’s Office (CCSO).

Authorities released a new suspect flyer Tuesday as the manhunt continues, showing potential alterations Decker could have made to his appearance.

Federal authorities have taken the lead in the search for Decker, with the U.S. Marshals Service and Washington National Guard aiding local police with aerial and ground searches throughout the remote areas. Last week, the manhunt stretched into the Ingalls Creek and Valley High areas as authorities believed they were zeroing in on Decker.

Officials are warning the public that Decker should be considered armed and dangerous, with the Marshals Service offering a $20,000 reward for any information leading to his arrest. He is charged with three counts of aggravated first-degree murder and kidnapping.

“Please secure your homes and vehicles, stay alert, and report any suspicious activity to 911,” the sheriff’s office previously posted to Facebook. “If you see something, say something.”

The CCSO did not immediately respond to Fox News Digital’s request for comment.
