19 year-old Kaytun Marsh will spend 60 years in jail for the death of Angie Dixon.
Prosecutors said Marsh shot Dixon during a robbery at her apartment in June of last year.
The jury deliberated for nine hours last month before reaching a guilty verdict on the murder charge.
He was found not guilty of robbery.
His two alleged accomplices, Brandi Philips and Blake Fisher will be in court later this summer.
