A woman who fled with her 21/2-year-old foster daughter rather than turn her over to biological relatives surrendered to authorities after nearly a month on the run, pledging to legally win her daughter back.

"You can't fight the system if you're not here, and I've got to fight the system and I've got to win," Kathryn Reiter, 37, said.Reiter spoke with reporters after relinquishing her foster daughter, identified in court documents only as Baby J., to a state Health and Rehabilitative Services worker. She would not say where she had been hiding.

Reiter fled with Baby J on March 9 after the court awarded custody of the child to cousins of her biological mother, a crack cocaine addict.
