Fortified Anderson underground bunker yields “alarming” illegal firearms stash; man arrested in marijuana cultivation probe
A CHP probe into suspected illegal marijuana cultivation in Anderson, California, led to the discovery of a fortified underground bunker, a cache of 13 illegal firearms and about 10,000 rounds of ammunition; Michael Jay Kamfolt, 40, was arrested.
- Search and discovery: A Jan. 20, 2026 search uncovered a fortified underground bunker accessed via a 100-foot culvert.
- Large weapons cache: Officers seized 13 firearms, four soft body armor vests, 30 high-capacity magazines and ~10,000 rounds, including armor-piercing ammunition.
- Charges and release: Michael Jay Kamfolt was arrested on multiple felony weapons counts and released on $50,000 bail.
- Investigation ongoing: CHP characterized the find as an “alarming” cache that expands the public-safety concern beyond an illicit grow.
What investigators found and how the case developed
CHP’s Northern Division says the probe began in December 2025 after its Canine Unit received a tip about suspected illegal marijuana cultivation. Investigators conducted an overflight and a month-long inquiry before obtaining and executing a search warrant on Jan. 20, 2026. Sources include the CHP news release, reporting by Fox News report and local coverage from Shasta Scout local reporting.
The bunker and access
Officers accessed a concealed underground facility through a roughly 100-foot culvert. The bunker featured a concrete floor, drainage, electrical power and ventilation. CHP described it as fortified and capable of supporting a sustained grow operation; investigators also found supplies consistent with cultivation. See the Fox News report and the CHP news release for official details.
Items seized
Inside the bunker and elsewhere on the property, officers seized a substantial array of weapons, ammunition and protective gear. Noted items include:
- 13 firearms — including three AR-15–style rifles, a sawed-off shotgun and at least two firearms reported stolen (2016 and 1978); one rifle had an obliterated serial number.
- Approximately 10,000 rounds of ammunition, reportedly including armor-piercing rounds.
- 30 high-capacity magazines and four soft body armor vests.
CHP called the collection an “alarming cache of illegal firearms and ammunition,” emphasizing that the threat extended beyond an illicit grow. (See the CHP news release.)
CHP official response and public safety concerns
“The operation went far beyond an illegal grow,” said CHP Northern Division Chief John Pinoli, warning that a hidden bunker combined with a large illegal weapons stash posed a clear threat to public safety.
CHP emphasized concerns for officers and neighbors given the presence of body armor and high-capacity magazines. The agency has characterized the find as expanding the investigation beyond narcotics enforcement and into significant weapons violations. (Official text: CHP news release.)
Charges filed and booking details
Michael Jay Kamfolt, 40, was booked on multiple felony counts tied to weapons statutes under California law. CHP-listed charges include:
- 30605(a) PC — possession of an assault rifle
- 30600(a) PC — manufacturing an assault rifle
- 33215 PC — manufacturing a short-barreled rifle
- 32625(a)/(b) PC — possession of and converting a firearm into a machine gun
- 30315 PC — possession of armor-piercing ammunition
- 32310(c) PC — possession of high-capacity magazines
Local records indicate Kamfolt had no prior criminal convictions in Shasta County. He was held overnight and released after posting $50,000 bail. CHP said the investigation remains active and declined to comment on any potential marijuana-related charges at this time. (Sources: Fox News report; Shasta Scout local reporting.)
Political ties and online activity
Local reporting found Kamfolt had engaged in political activity and activism, including support for Shasta County Supervisor Kevin Crye and attendance at election-related events. Crye called Kamfolt a friend and urged caution while also later posting a video to distance himself after the arrest. (See Shasta Scout local reporting.)
Reporters also noted Kamfolt’s social media footprint: an active X (formerly Twitter) presence that included reshared extremist content, described in coverage as pro‑Nazi, antisemitic and Islamophobic posts that alarmed members of the community.
Public reaction and online commentary
Online commentary was mixed. Some mockingly framed the bunker as a “prepper” setup — comments characterized the site as an apocalypse-ready hideaway — while others stressed the danger the weapons posed to neighbors and first responders. Local outlets asked how long the operation had run and whether any political connections influenced oversight.
Ongoing investigation
CHP said the probe is ongoing and that prosecutors may file additional charges as evidence is processed. Officials declined to provide further details about investigative steps or potential marijuana-related counts while the case is active. (Official updates: CHP news release.)
Implications for The High Desert
Economic impact
Headlines about an underground bunker and a large illegal firearms stash can harm the local image for small businesses that depend on tourism and outdoor recreation. Property values and buyer interest may be sensitive to reports of armed groups or violent crime, even when incidents appear isolated. Rural landowners may face increased scrutiny and inspection costs if illegal grows are suspected. (See local reporting: Shasta Scout.)
Political consequences
The arrest increases pressure on elected officials to address illegal grows and potential weapons trafficking in rural counties. For a politically moderate conservative audience, expectations often center on law-and-order measures, strong property-rights protections and transparency about any relationships between suspects and local officials.
Social effects
A hidden, fortified bunker and an illegal weapons stockpile can unsettle residents accustomed to low reported crime rates. Neighbors may call for more patrols, community-watch programs and clearer communication from law enforcement. The presence of body armor and armor-piercing rounds heightens specific safety concerns.
Cultural relevance
Prepper culture and armed self-reliance have a presence in parts of the High Desert. While some online reaction framed the bunker as a preparedness measure, many residents see a hidden, weaponized bunker tied to illegal activity as crossing into public danger. Local leaders will need to balance respect for lawful gun ownership with efforts to prevent illegal stockpiles.
Practical applications for residents
Property owners should secure remote parcels, especially those with culverts, outbuildings or abandoned infrastructure that could be exploited for illicit uses. Residents are urged to report suspicious activity to local law enforcement and to be cautious about renting land or providing access for cultivation operations. Community tips were central to this investigation; public cooperation remains vital. (See CHP guidance.)
