Elizabeth Johnson begins serving time at Perryville State Prison

A new mug shot has been taken of Elizabeth Johnson, baby Gabriel's mother, since a judge ordered her to prison in the disappearance of her son.

According to the Department of Corrections, Elizabeth Johnson is now serving her sentence in the health unit at the Perryville State Prison in Goodyear.

A jury convicted the 26-year-old of unlawful imprisonment and custodial interference.

Nearly three years ago, she left Arizona with her baby boy. She first told the child's father she killed their son. She then claimed she gave Gabriel away to a couple in San Antonio.

Johnson is set to be released in October of 2014.
