The Polaris Project, a nonprofit organization combating human trafficking, issued a report on Asian massage parlors in 2011.
The report detailed how brothels front as Asian massage parlors claiming to offer legitimate services such as massage and other health and spa services.
Typically, the massage parlors conceal the commercial sex operation by "registering and attempting to behave like legitimate business," according to the Polaris report. That includes paying rent to legitimate landlords, offering services that are legal, and using items commonly found in therapeutic massage parlors, such as massage tables.
One defining characteristic of Asian massage parlors is their location. They frequently operate in strip malls, office buildings and, occasionally, homes, according to Polaris. The businesses often use security cameras to screen and monitor clients as they enter and many have locked doors or use a buzzer system to control entry, according to the Polaris report.
Because the businesses are seemingly legitimate, they often advertise openly in newspapers, magazines, phone and online directories and on online community forums, such as Craigslist and Backpage. But they also advertise on sexually oriented websites and message boards, according to Polaris.
According to the report, the women working at the massage businesses are most often Asian women of diverse ethnicities and nationalities. They may have come to the U.S. on valid visas, fraudulent visas or may be undocumented and smuggled into the country, according to the Polaris report.
The levels of control and exploitation of the women working at the businesses varies, but in general, the businesses control the women through psychological abuse, threats, document confiscation, isolation, debt bondage or capitalizing on language barriers and their unfamiliarity with their surroundings, according to the report.
The report describes the massage parlors as an "extensive, sophisticated organized crime network with multiple controllers who act in concert with each other."
Vancouver police say they have found no evidence that anyone working at the Shumway business was doing so against her will.
