A witness saw a man pull Kamille into a dark Toyota Sequoia SUV on the night she disappeared. Kamille's father, Dominic, said Kamille probably knows the person who took her. He said she would never get in the car with a stranger.

"She's not no little girl that's going to go get in the back. She's not friendly like that," Dominic said.

The FBI has expanded the search for Kamille across state lines into Georgia.

Anyone with information on Kamille's whereabouts is asked to call Crime Stoppers at (205) 254-7777 or contact the FBI's Toll-Free Tipline at 1-800-CALL-FBI (1-800-225-5324) or the Birmingham Police Department’s South Precinct at 205-254-2793.

There is a $33,000 reward. Callers can remain anonymous.
