Authorities say a Los Angeles woman has been indicted on federal charges of producing child pornography and child sex trafficking, a month after she was identified in decade-old explicit photos.
A U.S. attorney's statement says 52-year-old Letha Montemayor Tucker, who goes by the nickname "Butterfly," was named in the indictment returned Tuesday by a grand jury.
Widely circulated pictures first found by federal authorities in Chicago in 2007 show a man and woman molesting a girl who was between 11 and 13 at the time the pictures were taken.
After cropped photos of the woman were released, public tips led investigators to Tucker.
They are still searching for the anonymous man.
It's not clear whether Tucker has hired an attorney. When she was arrested, her son called the allegations "ridiculous."
