Asked what kind of person his sister had been, he said, "She liked to dance a lot, crack jokes and be with the family."
Though she is now an adult, he said, he plans to keep a closer eye on Georgina than before. "I'm gonna sit there and make sure that she gets there and back home, be more protective."
A sister, Mayra DeJesus, said Gina spent Tuesday with her family -- with the focus on her, but not so much what she'd gone through. She described Gina as in "good spirits."
The long missing woman's aunt, Sandra Ruiz, told reporters that her recovery shows that anything is possible.
"If you don't believe in miracles," Ruiz said, "I suggest you think again, because it does happen."
Age: 21 when she was reported missing; now 32, according to the Cleveland Police Department.
Missing since: August 22, 2002, said Martin Flask, director of public safety for the police; a missing person report was filed the next day.
Clues: Knight's grandmother, Deborah Knight, told The Plain Dealer on Monday that the family had concluded that Michelle had left of her own accord because she was angry that she had lost custody of her son. That conclusion was supported by police and social workers, she told the newspaper.
But the missing woman's mother, Barbara Knight, told the newspaper that her daughter would never have broken all contact voluntarily.
Barbara Knight moved to Naples, Florida, about a year and a half ago, her neighbor Sheldon Gofberg told CNN.
But even after her move, Barbara Knight told The Plain Dealer that she often returned to Cleveland's West Side to search for her daughter, putting up posters seeking information about her.
She said she thinks she saw her daughter and an older man walking together at a shopping plaza several years ago, but the woman did not respond when she called Michelle's name.
Law enforcement action: The FBI website makes no mention of her.
