I'm interested in the risks/threats specific to the area too.
She apparently worked (past tense) in Eureka, from time to time -- a 3+ hour mountainous drive each way. I am a bit familiar with the area (Eureka more, it’s pretty bad off) and Redding seems to have a better economy, although both seem to struggle economically.
Please see below an excerpt from my earlier post on crime issues in the region (Also worth noting that Redding was named the #5 most dangerous place in the U.S. for women in 2012 because of high sex assault rates.)

From the kymkemp link below: "Sherri did have a job over the last few years that brought her into Humboldt County,” Totten said. “She worked for a company that had a branch in Eureka. She would travel from Redding to Eureka every so often to work here for a short time.” Even though Papini no longer works for the company, that is a connection to this area, Totten said."
My note on drug activities in the area (I mention this because the OP asked about illegal growing which is prevalent there): Humboldt County/Eureka (neighboring Shasta County) has a reputation as a major marijuana producer, and Humboldt has actually been named one of 28 “High Intensity Drug Traffic Areas” in the United States and there are very serious drug issues (meth, heroin) in Redding as well. The cartels are active in Humboldt, and the indication is that these are local cartels (especially the marijuana farm owners, who have long fought the DEA). Mexican/Colombian/other Central American cartels are also very powerful of course, running drugs through California, and up to Canada.
