EAST LONGMEADOW – Once again, a purported massage business at 611 N. Main St. is entangled in a massive human trafficking case.

According to Attorney General Maura Healey’s Office, three people were arrested in connection with the operation of “an extensive human trafficking operation” at the Feng Health Center on Dec. 13.

Feng Ling Liu, 50, her husband Jian Song, 48, both of Sunderland, and her daughter, Ting Ting Yin, 26, a New Hyde Park, NY, resident, were all arrested for allegedly trafficking women from New York to the Feng Health Center as well as locations in Hadley and Framingham for the purpose of having them perform sexual acts for profit.

The arrest of these three were part of an extensive sting performed by local and state law enforcement in Massachusetts and New York as well as federal agencies that closed down two separate alleged trafficking operations that were being investigated collaboratively by the AG’s Office, the Northwestern District Attorney’s Office, and the Northampton Police Department, with assistance from other departments. In all four people were arrested and 10 trafficking victims were identified in connection with illegal activities at five different businesses.

“Human trafficking is happening right here in our own communities across the state,” Healey said in a press release. “It is an egregious crime that victimizes vulnerable people, while traffickers profit. This is about the exploitation of human beings and my office will continue to prosecute these cases to hold traffickers and sex buyers accountable. We thank all of our law enforcement partners who assisted us in this major operation.”

Liu and Song were arrested in Sunderland by State Police assigned to the AG’s Office and Sunderland Police Department after search warrants were executed at their businesses and their home in Sunderland. Yin was arrested in New York.

In East Longmeadow, authorities allege Liu and Song received the bulk of the monies received from the sexual acts performed at 611 Main St. The husband and wife allegedly actively recruited women, advertised sexual services online and arranged for sexual encounters.

A listing for Feng Health Center was located by Reminder Publications on the website rubmaps.com, a website that maps erotic massage parlors with a logo that states the site is “where fantasy meets reality.” The site includes reviews hidden from the public and available only to those with memberships.

Advertisements for an unnamed massage establishment at 611 N. Main St. featuring photograph of a young Asian woman were also located on backpage.com, a website specializing in adult singles ads and escort services, as well as the Western Massachusetts craigslist.com page.

The Attorney General’s Office also alleged that trafficking victims were housed at 611 N. Main St., a building that is zoned for commercial use. East Longmeadow Health Director Aimee Petrosky confirmed it appeared the property had been used for housing.

“I can confirm I observed what appeared to be living quarters based on items present such as toothbrushes, medications and other personal items,” she said. “At the time of my original inspection there were a few individuals present who appeared to have been living there.”

A notice dated Dec. 13 and signed by Petrosky was affixed to the door at the Feng Health Center declaring the structure unsafe for human use and noting it was unlawful for any person to occupy the building between 5 p.m. and 9 a.m.

Another massage business, Korean Massage, was also closed down at the same location in 2013 due to concerns over human trafficking investigations. After the 2012 Annual Town Meeting voted to require licensed massage businesses to obtain a special permit, the Planning Board denied the application of Gye-Hwa Shin, a Flushing, NY, resident and owner of Korean Massage.

The Planning Board approved the special permit for the Feng Health Center in February 2014.

According to special permit documentation obtained from the Planning Department, at the time of application Liu maintained a residence at 84 Hillside Drive in East Longmeadow. She is listed as the sole owner of the business.

The special permit also states Liu would be the only massage therapist working at the site until the Planning Board approved additional employees and she must provide updated professional licenses to the Planning Department. According to the Board of Registration of Massage Therapy, Liu has a valid Massage Therapist Practitioner’s license, issued in 2008 and due to expire in May 2017.

Planning Director Robyn Macdonald indicated she intended to bring the matter to the Planning Board’s attention at its Dec. 20 meeting and anticipated the current special permit would be terminated for violation.

Macdonald added the board did have some power to prevent such activity from occurring in the future.

“The board can deny anyone coming in for a special permit at that location. Special Permits can be denied as long as the decision is not arbitrary or capricious,” she said. “The board could grant a Special Permit with specification requirements of the owner of the property which should keep things in check.”

According to the special permit and property information obtained from the East Longmeadow Assessor’s Office, the building is owned by Daniel Burack, local real estate developer and member of the East Longmeadow Board of Public Works. Burack was also owner of the property during the period of operation for Korean Massage. Burack was listed solely as owner of the property and not as a business owner for either enterprise.

Information provided by the AG’s Office indicates the neighboring salon also located at 611 N. Main St. was not involved in the investigation. They were also not implicated in the investigations or discussions involving Korean Massage and the owners spoke against the practices at that establishment in 2013.
