They told her they could help her get a job at a carnival. Instead, prosecutors say they trafficked her. The victim was able to text her ex-husband for help.
Bob Sanborn, with the human trafficking advocacy group, Children at Risk, said the victim was brave.

"To be able to reach out to call someone who she knew was going to be able to help her. One phone call and it's going to get there," said Bob Sanborn of Children at Risk.
Sandorn said the victim's ex-husband was out of state but he was still able to make one call and get help immediately. He called the National Human Trafficking Hotline.

"When you call this hotline, it goes to D.C., which is the call center, but they are working very closely with law enforcement all across the country to communicate what's going on and really to act on any significant tip," said Sandorn.
After calling the hotline, people there were able to get in touch with law enforcement in Houston, who then were able to get the woman and arrest the two suspects.
According to the hotline, Texas had the second highest number of human trafficking cases in 2016 and the numbers are only expected to go up this week because of the Super Bowl.
Police are also asking for your help. If you see anything give them a call or you call the national hotline at 1-888-373-7888 or www.humantraffickinghotline.org.
