A missing Arizona mother and her 3-year-old daughter who were kidnapped for ransom from their home are safe, but their captors are still at large.

Liliana Beatrice Iboa, 20, was abducted Friday with her little girl, Karen Bianay Cervantes.

Their kidnappers asked for $100,000 in ransom money, but released mother and daughter unharmed before midnight Monday, MyFOXPhoenix.com reported.

Iboa and her toddler daughter were dropped off in north Phoenix shortly before midnight. She flagged down a passing car that took her back to her home in Avondale, Ariz., and then called police — who are investigating but haven't yet found the captors, according to MyFOXPhoenix.com.

Iboa's family is thrilled she was found.

"It was a big relief," said her uncle, Joel Iboa. "I did fear the worst."

Iboa and her little girl were reported missing by Iboa's husband, Benito Cervantes Mena, shortly before 10 p.m. Friday. The home had been burglarized, but Mena told police he didn't report the crime immediately because he feared his family would be hurt.

The couple had recently reunited after a long separation, said Iboa's uncle.

"They were apart for a year or so," he said. "And then she moved back in with him on Sunday and then by Thursday, she gets kidnapped. It's just not — it couldn't be a coincidence."
