The mother of an Arizona baby missing for more than two years wants a felony child abuse charge against her dropped before her trial begins in September.
Elizabeth Johnson appeared in a downtown Phoenix court on Tuesday, shackled at the wrists and ankles and wearing a black-and-white prison uniform, her long brown hair pulled back in a ponytail.
The 25-year-old's attorney, Marc Victor, is seeking to get a child abuse charge against her dismissed, saying that there's no proof of child abuse and even if Johnson's 8-month-old son Gabriel was abused, it would have happened in Texas.
Johnson has pleaded not guilty to child abuse, kidnapping, custodial interference and attempted custodial interference stemming from the disappearance of Gabriel, who was last seen in San Antonio.
In December 2009, Johnson fled the state, taking Gabriel, who was 8 months old, to Texas. She initially said she killed the boy, but now she claims she gave him away to an anonymous couple.
