The report was sent to the Cherokee County district attorney on May 30, according to GBI spokesman John Bankhead.
“It is standard procedure in every police-involved shooting in the state we collect facts, compile a report and turn it over to the district attorney,” Bankhead said Tuesday of the GBI’s investigation. “They can be fairly lengthy, as we do a thorough job.”
The investigation came after Andrew Messina was shot and killed May 1 during a standoff with deputies which lasted for more than an hour at his Eagle Watch subdivision home.
After brandishing a .357 Magnum gun, pouring alcohol all over the curtains and threatening to shoot himself and his mother, Andrew died from a single shot fired by the deputy, according to police reports at the time.
The deputy involved in the shooting remains on administrative leave with pay, Sheriff Roger Garrison said.
Garrison said in addition to the investigation by the GBI, his department is also conducting its own internal affairs investigation into the incident.
“We are meeting with the district attorney on Wednesday to discuss the case and how we move forward,” Garrison said Tuesday afternoon.
According to the sheriff, the report is about 2,000 pages of data and interviews and his investigators are reviewing the case.
“We hope to have our internal investigation complete within two weeks,” he said.
At the time of the shooting Garrison said deputies were never able to establish rapport with the teen and called the incident a “very tragic situation” in which “there (were) no winners.”
The situation that led to the teen’s death came after the teen’s mother called 911 for help.
Though his mother exited the home prior to authorities arriving on scene according to 911 tapes, Andrew remained barricaded inside the home.
Just over an hour after Andrew’s mother called 911, authorities said the teen broke a glass window pane in the front door and pointed a gun toward deputies which led a sniper to take a single, fatal shot to the boy’s abdomen.
He later died at WellStar Kennestone Hospital in Marietta.
Based on information provided to authorities by his mother, the teen was on a combination of medications for depression and had been drinking alcohol, according to the sheriff at the time.
