Here is an FBI website which details what Human Trafficking is, how prevalent it is, and what they are doing to try to stop it:

..."Here in this country, people are being bought, sold, and smuggled like modern-day slaves, often beaten, starved, and forced to work as prostitutes or to take jobs as migrant, domestic, restaurant, or factory workers with little or no pay. Over the past decade, human trafficking has been identified as a heinous crime which exploits the most vulnerable in society. Among the Civil Rights Unit’s priorities is its human trafficking program, based on the passage of the 13th Amendment to the U.S. Constitution, which provided that “neither slavery nor involuntary servitude, except as a punishment for crime whereof the party shall have been duly convicted, shall exist within the United States.”
Under the human trafficking program, the Bureau investigates matters where a person was induced to engage in commercial sex acts through force, fraud, or coercion, or to perform any labor or service through force, coercion, or threat of law or legal process. Typically, human trafficking cases fall under the following investigative areas:
Domestic Sex Trafficking of Adults: When persons are compelled to engage in commercial sex acts through means of force, fraud, and/or coercion.
Sex Trafficking of International Adults and Children: When foreign nationals, both adult and juveniles, are compelled to engage in commercial sex acts with a nexus to the United States through force, fraud, and/or coercion. (Note: Matters of domestic juvenile sex trafficking are handled by the FBI’s Violent Crimes against Children Section.”
Forced Labor: When persons, domestic or foreign nationals, are compelled to work in some service or industry through force or coercion.
Domestic Servitude: When persons, domestic or foreign nationals, are compelled to engage in domestic work for families or households, through means of force or coercion..."
Here is another website, which specifically deals with Human Sex Trafficking issue in California; the group is called the Guardian Group:

..."While those statistics may already be shocking to most,
the sad fact is that they are on the rise in the U.S. and globally. What is being done about this very real war against human trafficking? For the most part, the answer is “We’re trying . . .” Human trafficking is truly at epidemic proportions and it’s showing zero signs of letting up or slowing down. Why? Most predators function on the fringes of social awareness. The crime can be masked in a variety of ways and, with the resources of our law enforcement agencies stretched thin, incidences of human trafficking can often fall off their “radar”."
