A mountain goat that fatally gored a hiker, then stood over the man and stared at people trying to help, had shown aggressive behavior in the past, Olympic National Park officials said Monday.
Robert Boardman, 63, of Port Angeles, died Saturday after he was attacked by the goat while hiking on the subalpine Switchback Trail in the park. The trail is popular with residents of nearby Port Angeles, which is about 85 miles west of Seattle.
Park rangers later found the goat, observed blood on it and shot the animal.
Rangers have been tracking the goat and others for the past four years because they have followed people or approached hikers without backing down, said park spokeswoman Barb Maynes.
"It has shown aggressive behavior, however, nothing led us to believe us it was appropriate to take the next level of removal," she said. "This is a highly unusual. There's no record of anything similar in this park. It's a tragedy. We are taking it extremely seriously and doing our best to learn as much as we can."
Park officials have posted signs at trailheads warning hikers to be watchful of all goats and to stay at least 100 feet from the animals. Hikers are also warned not to urinate on or near the trail, because goats are attracted to the salt.
A necropsy, or animal autopsy, was conducted on the goat Sunday night by a private certified veterinary pathologists. Park officials are awaiting test results of blood and tissue samples, which may take a couple weeks, Maynes said.
"We're looking for anything to indicate any presence of diseases, which might shed light on the animal's extremely strange and unusual behavior," she said.
Boardman was hiking with his wife, Susan Chadd, and their friend, Pat Willits, and had stopped for lunch at an overlook when the goat began acting aggressively toward them, the Peninsula Daily News reported.
Boardman urged the others to go ahead while he tried to get rid of the goat, according to the paper. The two heard him yell and ran back to help.
Hikers who came upon the group radioed for help. But it took nearly an hour before rescuers could reach Boardman because the goat stood over him as he lay motionless on the ground, according to the Seattle Times.
"The mountain goat was terribly aggressive," Jessica Baccus, who was hiking with her family, told the Times. "It wouldn't move. It stared us down."
She and her husband, Bill Baccus, a park scientist, tried to lure the goat away by pelting the animal with rocks, shouting at it and using a silver reflective blanket to distract it. It finally moved away, and Jessica Baccus tried to give Boardman CPR until a local doctor who came upon the group took over, she told the Times.
A U.S. Coast Guard helicopter airlifted him out of the park.
Boardman, a locally-known musician and diabetes educator, was an avid hiker who also worked for years as a nurse for the Makah and Lower Elwha Klallam tribes, according to the Peninsula Daily News.
About 300 goats graze the park's alpine meadows and roam its rocky peaks. The animals are not native to the park and were introduced in the 1920s, before the park was established.
Maynes said the park had a two-year live capture program in the late 1980s to remove the goats by helicopter because of the damage the animals wrecked on the park's fragile alpine areas and soil. That program was ended after two years because it was determined to be risky for operators and was less effective, she said.
Wild animals are unpredictable, and thus dangerous.
In Alaska, moose encounters are common, even in urban settings, but rarely do they turn deadly. The last known fatal attack occurred in 1995, when a 71-year-old man was stomped by a cow moose apparently protecting its calf. The moose was killed a week later when it tried to attack another person.
A Michigan man was killed and two others injured when an undernourished grizzly and her three cubs marauded through a crowded campground near Yellowstone National Park on July 28. The mother bear was euthanized, and the cubs were taken to a sanctuary.
A month earlier, a botanist in Wyoming was killed by a bear shortly after the animal woke up from being tranquilized by researchers.
In New Mexico this year, more than 80 bears that were roaming too close to people and searching for food have been killed.
