Family reaction: DeJesus arrived at a family home Wednesday afternoon. A large crowd greeted her arrival with cheers.
Her father, Felix DeJesus, said he never doubted his daughter was alive. "I knew she needed me and I never gave up, I never gave up searching for her."
Sandra Ruiz said her niece is "ecstatic" to be back with her family. When she arrived Wednesday afternoon at a family home, "she was happy, she looked at the house and she wanted a tour."
"What more can she say -- her face, her expression, her smile, (her) hugging says it all," Ruiz said.
Wednesday evening, Pastor Angel Arroyo told CNN's Piers Morgan: "The family is totally overwhelmed, and grateful and happy."
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 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.
Law enforcement action: The FBI website makes no mention of her.
Family reaction: News of her discovery came as a shock to brother Freddie Knight, who didn't know she was missing until he saw the story on TV. He said the family thought Knight might be with the brother of a brother-in-law, but had no phone number to contact him.
"I was freaking happy as hell, because I didn't know my sister was kidnapped," he said.
Barbara Knight told NBC on Wednesday she had not yet spoken to her daughter.
"She's probably angry at the world because she thought she would never be found, but thank God that somebody did," she told NBC.
She was asked what she would say to Michelle if and when she got to see her. "I love you and I missed you all this time," Barbara Knight said.
