PHOENIX -

An Arizona woman who was convicted in her young son's disappearance nearly three years ago has been sentenced to five and a quarter years in prison.

26-year-old Elizabeth Johnson will get credit for about three years that she has been in jail.

Johnson was convicted of custodial interference and unlawful imprisonment in October in the 2009 disappearance of her then 8-month-old son, Gabriel. The jury failed to reach a verdict on a kidnapping charge.

Authorities said Johnson told the boy's father that she killed Gabriel and dumped him in a trash bin, but she recanted and told police she gave the infant to a couple at a San Antonio, Texas, park. She never provided the couple's names, authorities said.

Authorities don't know if Gabriel is still alive.

Prosecutors alleged that Johnson ran off to Texas with the child as a way to retaliate against his father for ending their tumultuous relationship.
