Gwinnett Police Cold Case Unit Solves Murder From 2012

(Lawrenceville, Ga., September 25, 2020) – The Gwinnett County Police Department’s Cold Case Unit has obtained warrants for Nazar Matheson for the murder of Robert Mixon on November 2nd, 2012.  A detective assigned to the Cold Case Unit has been investigating this case with the Gwinnett County District Attorney’s Office for years.

Mixon was shot to death inside his apartment on Satellite Boulevard in 2012.  Detectives originally assigned to the case spoke with witnesses and fielded tips but were never able to identify a suspect.  The case was eventually assigned to a Cold Case Investigator.  That detective was able to locate DNA evidence which linked Matheson to this murder.  Matheson was already incarcerated for unrelated crimes in Georgia.  After identifying Matheson, the detective worked with the Gwinnett County District Attorney’s Office to obtain more evidence linking Matheson to the murder.

The police department is still asking anyone with information on this case to come forward now that Matheson has been charged.
