CHICAGO – Days after police stormed a southwestern Illinois home on the allegation that a teenage girl had been held captive and forced into sex, authorities wouldn't say whether an ongoing investigation would result in additional charges.

Two people were charged in the case on Saturday, but none of the charges allege that the St. Louis, Mo., woman, now 19 years old, was held against her will for more three years.

"We are still investigating," Washington Park Police Chief David Clark told The Associated Press on Sunday. He declined to comment further.
