Carruth, 44, left the Sampson Correctional Institution in Clinton, N.C., at 8 a.m. ET without speaking to reporters gathered near the exit.
Rae Carruth (shown during a 2005 court appearance) will leave prison Monday.
Former Carolina Panther Rae Carruth released from prison. It appears that the National Football League has blocked Carruth's name from appearing on any jersey, regardless of team or number.
Carruth, now 44, was found guilty of orchestrating a plot to kill Cherica Adams on November 16, 1999, in Charlotte, North Carolina, to avoid paying child support.
Carruth was also convicted of shooting into an occupied vehicle and using an instrument to destroy an unborn child in connection with the death of 24-year-old Cherica Adams. Adams was seven months pregnant at the time. Adams was eight months pregnant at the time, and their son, Chancellor Lee Adams, was born via C-section before she died. Their child, Chancellor, survived the shooting but suffers from cerebral palsy as a result.
Carruth apologized for his role in the murder and has said that he wants a relationship with his son.
Carruth was found guilty of multiple charges relating to the murder of Cherica Adams in 2001 and was sentenced to a minimum of 18 years. A friend of Carruth's named Michael Kennedy - who drove a third auto behind Carruth and Adams - as well as a passenger in that vehicle, Stanley Abraham, have since been released from prison, according to the Observer.
Chancellor's grandma, Cherica's mom Saundra Adams, is raising him.
Rudolf said in an interview that Carruth still maintains Watkins shot Adams on his own as an act of violent retribution after Carruth backed out of an agreement to finance a drug deal.
Carruth said he hopes to "make things right" with both of them.
Saundra Adams vowed in February that Carruth would never have custody of his son. But I can say definitively he's not ever going to have custody of Chancellor.
He was taken to an undisclosed location after his release.
Wherever Rae lives, he will occasionally have to meet with authorities for the next nine months, as part of his release requirements.
