Detectives with the Orange County Sheriff's Office are asking the public, especially those who lived in the Parramore area in the 1970s, to jog their memory and help them bring closure to the families.
Nancy Grace Daniel disappeared when she was 14 years old. "Nancy didn't have any enemies," said the victim's brother, Willie Daniel.
She was last seen near Parramore Avenue and Anderson Street in 1976. Her cousin, Eugenia Oliver, was the last person to see her alive. She talked about the places they use to hang out.
"'Wooden Nickle's' and then when it changed over it was called 'LC,' right there in Parramore between Emerson and South Street," said Eugenia Oliver, the victim's cousin.
In 1977, Nancy's bones were discovered not too far from her home. A second set of human remains were also discovered. Both sets were unidentified for decades.
"As long as she was gone, I never thought she was dead," Willie said.
As technology advanced, and with the help of two retired detectives from the National Center for Missing and Exploited Children, detectives identified Nancy's bones last month. They also came up with a computer generated picture of the second human remains they call Jane Doe. But she hasn't been identified yet.
Now, the Orange County Sheriff's Office, Orlando Police Department and Crimeline are teaming up to go back in time and figure out what happened to these two girls.
"We're hoping to reach the long time or should I say older members of our community," said Orange County Sheriff Jerry Demings.
"If they think they got away with it like the detectives said, this will never go away," Willie added.
There's a $5,000 reward for any information the disappearance of Nancy Grace Daniel, call Crimeline at 800-423-TIPS (8477).
