A man hiking in the Idaho wilderness says he was mistaken for fugitive child murder suspect Travis Decker, who has been on the run since May 30.

Decker faces charges of murdering his three daughters — Paityn, 9, Evelyn, 8, and Olivia, 5 — who were discovered at Rock Island Campground on June 2. Their mother had reported them missing three days prior when they failed to return from a court-mandated custody visit with their father.

U.S. Marshal Supervisory Deputy Michael Leigh stated that on July 5, the USMS Greater Idaho Fugitive Task Force received information from a family in the Bear Creek area of Sawtooth National Forest in Idaho. They reported seeing a man matching “the description of Travis Decker.”

“The individual believed to be Travis Decker was detailed as a white male between 5’8″ and 5’10″. He was wearing a black mesh cap, black gauged earrings, a cream-colored t-shirt, black shorts, a long ponytail, an overgrown beard and mustache, a black Garmin-style watch, a black Jan Sport backpack, and either Converse or Vans low top shoes,” according to a USMS release on July 7.

The U.S. Marshals Service is offering a $20,000 reward for any information leading to Decker’s arrest.
