The Long Island Greek-American Chamber of Commerce on Tuesday hosted a training program in Uniondale at which experts educated businesses on ways they can help curb human trafficking on Long Island.

"It's an insidious crime against humanity," the commerce's George Tsunis says of human trafficking.

Last week, News 12 reported on Raymond Rodio, who investigators say was a human sex trafficker using his parents' basement in Sound Beach as a brothel for years.

Sue Lingenfelter, of Long Island Against Trafficking, says the industry is growing exponentially and is profitable.

Keith Scott, director of education at the Safe Center in Bethpage, says traffickers exploit hotels and motels -- especially ones with hourly rates.

Experts say there is a lot of false information out there surrounding human trafficking. One is that most victims are coming from other countries. Scott say 80% of sex trafficking victims in the U.S. were born in the country.

New York City and Long Island are among the top 20 spots in the nation for human trafficking.
