Bradley sisters' cold case still haunts Chicago 15 years later

Two little girls who left a note for their mom disappeared from Chicago's South Side 15 years ago and have never been seen again.

10-year-old Tionda and 3-year-old Diamond Bradley were last seen on July 6, 2001. They left a note for their mom saying they went to a school and a store.

But six o'clock that night, they hadn't returned.

The girls would be 25 and 18 now. Police have released an age progression photo of what they may look like.

There is a $10,000 dollar reward for their return.

A private detective and retired police officer have been investigating thousands of leads over the years. so far, none of them have panned out.
