Bellingham, Wash. — A Whatcom County man accused of kidnapping two U.S. Forest Service employees during an armed standoff in Northern California had previously been the subject of repeated law enforcement responses and serious mental health concerns before ultimately being released from state custody.

Joseph Charles Henrichsen, 49, and his son, Phoenix Henrichsen, 23, are facing federal charges after authorities say they held two U.S. Forest Service biologists at gunpoint in California’s Shasta-Trinity National Forest. The incident sparked a roughly 15-hour standoff before the FBI’s Hostage Rescue Team negotiated the safe release of the hostages and the surrender of both suspects.

According to federal prosecutors, the biologists were conducting frog surveys near Gumboot Lake when they were confronted by the armed father and son. Investigators allege the victims were restrained with zip ties before being held during the lengthy standoff. Both defendants have pleaded not guilty to federal charges that include kidnapping government employees, assault and firearms offenses.

The case has also drawn renewed attention to Henrichsen’s history in Whatcom County, where neighbors reported years of escalating threats and erratic behavior leading up to his 2022 arrest.

Court records indicate residents living near Bellingham repeatedly contacted law enforcement after Henrichsen allegedly intimidated neighbors while openly carrying firearms, launched fireworks, assaulted an elderly man and used a loudspeaker to broadcast accusations aimed at nearby residents. Several neighbors reportedly warned authorities they believed he posed a serious danger.

His arrest came after investigators say he left a threatening note alongside two zip ties arranged to resemble handcuffs outside a neighbor’s home. Following the arrest, Whatcom County Sheriff’s Office deputies seized approximately two dozen firearms from his property.

A court-ordered competency evaluation concluded Henrichsen was likely suffering from schizophrenia or another psychotic disorder and recommended inpatient psychiatric treatment. A judge ordered he be admitted to a state psychiatric hospital, but he remained in the Whatcom County Jail for more than four months while waiting for an available bed.

During that delay, the Washington State Department of Social and Health Services cited increased demand for psychiatric treatment and pandemic-related limitations. A judge later found the agency in contempt for failing to meet the court’s deadline and imposed daily financial penalties.

After Henrichsen was eventually transferred, criminal charges were dismissed on due process grounds. Records indicate Western State Hospital later declined to civilly commit him under Washington’s Involuntary Treatment Act, which requires specific legal standards to be met before someone can be involuntarily hospitalized.

Neighbors who had repeatedly reported Henrichsen’s behavior expressed frustration with the outcome, saying they had warned authorities they believed he remained a threat if released.

The recent California incident has renewed questions about Washington’s handling of individuals experiencing severe mental illness within the criminal justice system, particularly when treatment delays and legal requirements prevent long-term psychiatric commitment.

No serious injuries were reported during the California hostage incident, which authorities credited to extensive law enforcement training, successful negotiations and the safe surrender of both suspects.
