Tionda and Diamonds great aunt, Shelia Bradley-Clark, have been searching for them for 18 years.
She sent the following statement to CBS 2 Friday night:
"With disturbing regret, MISSING DIAMOND AND TIONDA BRADLEY sought to continue. Unfortunately, the information on social media from this group of scammers is NOT MISSING DIAMOND AND OR TIONDA BRADLEY. Hopes that everyone will continue to give some tips on where Diamond and Tionda Bradley are. We thank the Community, the Law Enforcement Community, the news covering this heartbreaking HOAX, and we also thank the private investigator and all the tips given for to reveal those responsible for this CRUEL AND EVIL ACT. "
" It's so emotional I can't even describe it, "Bradley said -Clark. "It still feels like yesterday."
On Friday, she spoke on the phone from Minneapolis about Facebook messages sent by a Texas woman who said she would take a DNA test to prove she is Tionda.
Bradley-Clark's great niece was just 10 years old when she walked away from her South Side neighborhood with her 3-year-old sister Diamond back in 2001.
Police scour the area but never found them.
"I have to control my feelings with this because what if it's not her? What if someone is playing a cruel joke?" Bradley-Clark said.
Pastor Paul Jakes, who served as spokesman for the family over the years, said he prayed that it was her and not a hoax
"We've done so much over the years," Jakes said. "I have always believed that these children would be found."
But he has followed up on other false tips in the past.
"The daughter must make herself available, give a blood test and collaborate with authority," said Jakes.
The family's private investigator said the Chicago police and the FBI were aware of the claim and investigated it.
Bradley-Clark said that scientists ordered an accelerated DNA test to prove whether she is one of the lost girls.
"I hope with all hope I have it. If that is not the case, she just has to get legal consequences, "she said before the news.
On Friday, the Chicago police would not confirm their involvement in this case.
Rev. Jakes said that although it turns out to be a dead end, he hopes that it will bring renewed attention to the girls' disappearance.
