A massive two-year investigation on human trafficking in North Florida resulted in more than 170 arrests, according to Florida police.

The charges came from the multi-agency probe called "Stolen Innocence." These charges range from solicitation of prostitution to human trafficking of a minor, says police in Tallahassee, Florida.

The investigation started in November 2018 after investigators discovered images of a child on a website advertising sex, according to a New York Daily News report.

Tallahassee Democrats reported that the girl involved was between ages 13 and 14 when the alleged offense happened.

"It is difficult to comprehend the depravity of these criminals who prey on the most innocent in our society," Kevin Sibley said in a statement. Sibley is the acting special agent in charge of Homeland Security Investigations in Tampa.

More than 100 suspects were charged with felonies, according to officials. A total of 19 suspects face federal charges, as said by the U.S. Attorney's Office for the Northern District of Florida.

U.S. Attorney Lawrence Keefe said the victims of sex-trafficking crimes need their help. Keefe noted that as a society, everyone must do their part to be there for the victims in any way that they can.

"For so long as I am the United States Attorney, I will do everything I can to contribute to multi-agency efforts, to make federal resources available, and to assist your State Attorney, your police department and your sheriff as they protect our children and guard this community," Keefe added in a statement.

Police Chief Lawrence Revell said the investigation discovered numerous electronic evidence that would need months to evaluate. The electronic evidence allowed investigators to develop and extend the scope of the case.

Revell said the investigation is proof of how diligent their investigators work to enhance the quality of everyone's life in the community, particularly those part of the vulnerable population.

He added that he could not be prouder of their investigators and partners' steadfast efforts to stop the illegal and dehumanizing practice of human trafficking.

Revell said the investigation was likely the biggest of its kind in Tallahassee history, despite the officials' initial refusal to acknowledge it.

The federal charges included in the case are enticement and coercion of a minor to engage in sexual activity. It also included enticement and coercion of a minor to engage in prostitution, production, and/or receipt of child pornography, transfer of obscene material to a minor, sex trafficking a minor, and conspiracy to sex traffic a minor.

Sibley thanked the overall efforts of the Tallahassee Police Department and HSI special agents. He also cited that local communities are significantly safer today as a result of this investigation.

The agencies involved in the investigation of human trafficking in Florida are the Tallahassee Police Department, the Department of Homeland Security Investigations, the U.S. Marshal Service, the Florida Department of Law Enforcement, and the Leon County Sheriff's Office.

Assistant U.S. Attorney Michelle Spaven will be prosecuting the federal cases involved in the investigation.
