Local, state and federal agencies in northwestern Wyoming are seeking the public's help in finding a suspect in a triple homicide in Idaho last month, according to the National Park Service Investigative Services Branch Tuesday.

Meanwhile, agencies in the manhunt for Gerald "Mike" Bulllinger in the Bridger-Teton National Forest have closed the Pacific Creek Campground for public safety.

Likewise, authorities have closed the Lava Creek, Box Creek, and Clear Creek trails, and all the area surrounding Enos Lake in the Teton Wilderness Area.

The road closure on the Pacific Creek Road begins at the forest boundary. Pilgrim Creek Road in Grand Teton National Park has also been temporarily closed.

Bullinger, 60, is a person of interest in the shooting death of his wife -- Cheryl Baker of Ogden, Utah -- a teenager and another adult, whose bodies were discovered in a shed in Caldwell, Idaho, on June 19. Baker's car was found in a remote campground north of Moran

Bullinger is described as a white male 6-feet 1-inch tall, weighing 240 pounds, with gray hair and brown eyes. He was last seen wearing a ball cap.

He is possibly armed and considered dangerous.

Agencies in the manhunt want to talk to people who camped at the Pacific Creek Campground in the Bridger-Teton National Forest from June 1 to Monday to determine if any of them encountered Bullinger, according to the news release.

Whether whether you may have seen Bullinger or not, you may be able to help investigators. The Sheriff's Office wants to interview anyone who spent time at the campground about the time his wife's car was abandoned.

Agencies involved in the search include the Teton County Sheriff's Office, the U.S. Forest Service, the Federal Bureau of Investigation, the U.S. Marshals Service, the Wyoming Game and Fish Department, and the Teton County Emergency Management. The agencies also are using cadaver dogs.
