One Illinois family has lived with the unimaginable for 25 years with no closure. The FBI is asking for the public's help in solving the mystery of two young sisters in Illinois that suddenly went missing on a July afternoon in 2001.

The FBI in Chicago has just shared a plea on social media in the case of Tionda Z. Bradley and her sister Diamond Yvette Bradley. They left a note saying they were going to the store and playground on July 6, 2001 and were never seen again.

Here's the exact words of the FBI in case you can't read the small print or social share on your device:

"Can you help #FBIChicago solve this case? It's been 25 years since sisters Tionda and Diamond Bradley were reported missing. Tionda, who was then ten-years-old, and Diamond, who was then three-years-old, were said to have left a note stating they were going to the store and school playground. An extensive search were met with negative results and the girls have been missing ever since.

The FBI is offering a #reward of up to $10,000 for information regarding the current whereabouts of Tionda and Diamond Bradley. You can submit a tip (even anonymously) by calling 1-800-CALL-FBI (225-5324), online at tips.fbi.gov, or by calling the FBI Chicago Field Office at 312-421-6700."
