The Incident
On the morning of July 16, two female U.S. Forest Service biologists were conducting frog-habitat research near Gumboot Lake Campground in the Shasta-Trinity National Forest, Siskiyou County. According to a federal affidavit, 49-year-old Joseph Charles Henrichsen approached the scientists with an AR-15-style rifle, ordered them to raise their hands and zip-tied their wrists. He forced the pair into a nearby white camping trailer where his 23-year-old son, Phoenix Henrichsen, joined him.
The victims remained bound for more than 12 hours. Joseph drove one biologist several miles away in a Forest Service Nissan, left a voicemail for a ranger, and later returned her to the trailer. He also claimed to possess a grenade and threatened its use. FBI Hostage Rescue Team negotiators secured the release of the first biologist at 1 a.m. July 17, followed by the second six minutes later. Both suspects surrendered shortly thereafter, with Phoenix exiting the trailer around 2:30 a.m. and Joseph five minutes later.
