LAWRENCEVILLE - Authorities have made a third arrest in the December shooting death of a Lawrenceville man that resulted when a drug deal skidded out of control, according to police.
Police arrested and charged Zachary David Bivens of Grayson with murder and possession of marijuana Friday.
Bivens is accused of playing a role in a drug deal turned botched robbery that left Robert Morales, 27, dead with a single gunshot to his chest two days before Christmas in a Grayson subdivision.
Police spokespersons were out of the office Monday and couldn't say exactly how Bivens allegedly factors into the slaying. His Hillside Drive address is the same road on which the double-shooting took place, according to jail records.
Another murder suspect, Omar Falay, 17, was inadvertently shot by an accomplice in the fracas but survived, police said. He remains in the Gwinnett County Jail without bond.
A detective testified last month that Falay and an unidentified shooter tried to rob Morales and his friend, Eric Comrie, 21, of drugs and valuables from the back seat of Comrie's car but Morales fought back. The shooter allegedly killed Morales and accidentally shot Falay as the two struggled outside Comrie's 1998 Mercedes.
Police believe the same .45-caliber handgun that injured Falay was used to kill Morales.
Morales died about 30 minutes later at Eastside Medical Center, while Falay fled to a neighboring subdivision, solicited help and was transported via ambulance to Gwinnett Medical Center. He was arrested there later.
The shooter, police said, fled on foot.
Also charged with murder, Comrie, the alleged driver, was freed from jail on Jan. 8, records show. He fingered Falay as one of the robbers but not the shooter, police said.
Jail records show Bivens is a student, but a Gwinnett County Public Schools spokesperson said he's not enrolled in the local system. On Monday it was unclear how old he is.
