Suspect Identified 2 Years After Teen Slaying

MARIETTA, Ga. — Marietta police have secured a warrant for a suspect in a 2-year-old murder case. A second shooter remains at large.

Dequonist Marquez Lucas, 26, is accused in a July 2008 armed robbery of two boys on a Marietta street corner. Police said during the robbery, 16-year-old Samuel "Dra" Steward was shot in the head and left to die at the intersection of Allgood Road and Avery Street.

One of Steward's cousins told police he dropped Steward off at home earlier after spending time with him at the Elizabeth Porter Recreation Center.

"If I hadn't talked to him throughout the day, I go over there at nighttime. I got to see him," the cousin told Channel 2's Ryan Young two days after the killing.

Police said Steward left his house and was attacked while walking. Hours later, he died at Kennestone Hospital.

After years with no arrests, police said they were led to a witness this month. Through subsequent investigation, they secured a felony murder warrant for Lucas. He was being held at the DeKalb County Jail on unrelated charges.

Lucas was charged with murder in the death of a pregnant DeKalb County mother in October 2008. Police said Quishanna Loynes was struck by a stray bullet in front of her three young children.

The other suspect in Steward's killing is described as a 6-foot-tall light-skinned black man with dreadlocks. Anyone with information is asked to call Marietta police at 770-794-6990.
