The search has intensified for the Washington father suspected of murdering his three daughters before fleeing into the wilderness. This comes after campers in nearby Idaho reported a possible sighting during the holiday weekend.

The U.S. Marshals Service Greater Idaho Task Force was informed by a family that they saw a man matching the description of 33-year-old Travis Decker while they were camping in the Bear Creek area of Sawtooth National Forest on July 5, as reported by Fox 13.

According to the report, the family described the individual as wearing a black mesh cap, a cream shirt, black shorts, and black gauged earrings, standing between 5’8″ and 5’10″ tall.

The individual was reportedly carrying a black Jansport backpack and had a long ponytail and overgrown facial hair. He was wearing a black watch and either Vans or Converse low-top shoes.

The girls’ mother, Whitney Decker, spoke publicly about the loss of her children last month. 

“I truly hope that the legacy of the girls’ lives on in everyone’s heart forever,” she said at a June 20 memorial service, according to Fox 13 Seattle. “They were incredible.” 

Authorities warn that Decker should be considered armed and dangerous but insist they have no reason to believe he is a threat to public safety. He is charged with three counts of aggravated first-degree murder and kidnapping.

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