A Humboldt County medical marijuana company has sued a local insurance agent for fraud and embezzlement, alleging that it gave the agent $50,000 to buy a workers’ compensation policy that was never delivered. Humboldt Redwood Healing sued John Ford, of the Eureka-based John Ford Insurance Agency, in October. The company also reported Ford to local authorities, and the district attorney’s office searched the premises at Ford Insurance on Oct. 21, according to Humboldt Redwood Healing CEO Thomas Mulder.
