"A lot of juveniles do not identify themselves as victims, and it takes several interviews of going back and getting the trust of the juvenile to let them know that we are there to help them," police Sgt. Nicole Donnelly said.
If the girls are minors, police check to see whether they are reported missing and will try to reunite them with family.
Ferrer, the U.S. attorney, says his office is pleased with the new approach.
"We are very happy that the state has changed the laws and amended to help these victims come forward and declare themselves as victims without fear of prosecution," he said. "That is very helpful."
CNN accompanied undercover officers in about 10 patrol cars on an operation to dissuade prostitutes from working on the streets and to rescue minors from the sex industry.
While patrolling one of Miami's known prostitution "tracks," officers came across a youth who identified herself as April, like the woman at the beginning of the story. This April told officers she is 24 and has been working the streets since she was 21.
April has two children, ages 2 and 4, and works as a prostitute to pay for their needs and for her education, she said.
Initially, it was a boyfriend who get her involved in prostitution.
She was working as a stripper, she said, when she met the guy, who promised her clients and money. He made it sound easy.
The first time she stood out on the corner, it was against her will, but she liked the guy, said April.
"And then, the money. It gets addicting," she said.
It is a life that she never imagined. She had been in juvenile detention when she was younger and had met girls who had been prostitutes and told herself she would never go down that route.
But after being pulled in that first time by her boyfriend, lack of economic opportunities influenced her to continue.
"I want to stop," she said.
"If I can find a job."
