The FBI is asking for help from the public in a nationwide search to find a woman shown in a video of a child being sexually exploited.
The woman, referred to as Jane Doe 39, is seen and heard in a video that featured a child victim of sexual abuse, according to the FBI. The FBI has released audio of the woman's voice (video below).
The video, which the FBI believes was filmed before April 2016, was obtained during an FBI investigation and shared with the National Center for Missing & Exploited Children. Investigators then determined that the video had been shared online.
"We know that the video has been traded on the Internet and we know this child is a victim who needs our help," said Special Agent Susan Romash in an FBI release. "Our hope is that someone will recognize this individual's face -- or her voice -- and come forward with that information."
Jane Doe 39 is an Asian woman, likely between the ages of 25 and 35 with long black hair. In the video, she is seen wearing a white, yellow, blue and red floral dress and is heard speaking Vietnamese, according to the FBI.
In the audio released by the FBI, Jane Doe 39 is heard saying "you can't play with this" in Vietnamese.
The FBI and the NCMEC frequently work together on cases involving images of child pornography, according to the FBI's release. By investigating images, agents can find hidden metadata that leads them to a suspect.
"We also search for clues within the images," Romash said in the release. "Those clues often help us determine where the image was produced or who created it. If those approaches don't work, but there is an adult in the image whose face is shown, we publicize it through [Endangered Child Alert Program] and ask for the public's help."
ECAP is FBI's method of calling for public help to identify an adult seen in an image or video of child pornography.
ECAP was created in 2004 and resulted in 40 child victims being freed and the identification of 26 John/Jane Does, the FBI notes.
There are currently 13 people on the ECAP Most Wanted list, a list that operates similarly to the FBI's famous Ten Most Wanted list.
The list has led to suspects' faces being broadcast on national television shows such as "America's Most Wanted" and "The O'Reilly Factor," according to the Department of Justice.
