To this day, authorities have not been able to find the couple or determine if Gabriel is still alive.
Tammi Smith has denied any involvement in Gabriel's disappearance and was found guilty of forgery and conspiracy to commit custodial interference. She was sentenced to 30 days in prison, according to the Maricopa County Attorney's Office.
In 2012, Johnson was convicted of unlawful imprisonment, custodial interference, and conspiracy to commit custodial interference — she was never charged with murder since authorities could not prove that Gabriel was dead. At her sentencing, she apologized for taking Gabriel away but denied that she hurt him.
"I have to live every day without my son and without knowing where he is,” she said, People reported. "That is the worst pain and punishment I could ever have."
