Anthony Kenner, Alphonso Banks and Rebecca Forward were all sentenced to life without parole by Judge William Wright.
All three were arrested in connection with the death of 66-year-old Jay Shah. Prosecutors said Shah was bound and gagged so tightly with duct tape that he suffocated during a robbery last summer.
The two men, Kenner and Banks, were convicted of the murder, and Rebecca Forward pled guilty to her part in the crime.
