Lauderdale County, Miss. Jessie Jones and Quincy Fox were arrested in the kidnapping and robbery of two women outside a Meridian hospital in January 2012.
Fox has now been sentenced to a long prison term.
The two suspects were originally charged with robbery, carjacking and kidnapping of the two women, who were leaving work late in the evening at Rush Hospital when the two men came around the corner with a gun.
The victims were forced to drive to an ATM and retrieve money.
Fox is a habitual offender. He was sentenced this week to four life sentences, without parole.
"If you have a crime of violence in your past and you've served over a year in prison on that crime, and you have two felonies, then you get what's called the 'big habitual', which is life without parole," said District Attorney Bilbo Mitchell. "And that's what we were able to do with Mr. Fox."
Fox had already been convicted of multiple robberies.
Mitchell says Jones was a cooperative witness. His case is pending until October.
Neither of the women were physically injured, but Mitchell says this was a very traumatic experience for both of them.
