DeKalb County Superior Court Judge Gail C. Flake sentenced Demarcus McClarin of Lithonia on July 14 to two consecutive life sentences plus five years for the 2008 murder of 36-year-old Mac Mayer. McClarin shot and killed Mayer on April 9, 2008, while McClarin was robbing his mother, Ad Mayer-Lillard, at gunpoint in the parking lot of Belvedere Theater on Columbia Drive in Decatur which she owned.
Mayer died from a single shot in the back.
McClarin had previously served at least three years in prison for illegally receiving and transporting firearms before he was released on Jan. 18, 2008.
A DeKalb jury convicted McClarin on June 26 on seven felony charges including malice murder, felony murder, armed robbery, two counts of aggravated assault, possession of a firearm during the commission of a crime and possession of a firearm by a convicted felon.
Assistant district attorneys Courtney L. Johnson and Zina B. Gumbs prosecuted the case.
