BRUNSWICK -- Authorities are trying to determine whether a 2-year-old girl caused the shooting death of a man.

Curtis Gabriel Collins, 22, died after being shot in the head at a home around 8:30 p.m. Tuesday, police said.

Witnesses told police Collins was sitting on a sofa when the child grabbed at a gun on a table in the room, causing the gun to fire.

But Glynn County Coroner Jimmy Durden says a medical examiner from the Georgia Bureau of Investigation has withheld a ruling on whether the death was an accident or homicide until police complete their investigation.

The medical examiner recommended additional forensics tests, Durden said.

The gun likely will be examined to determine whether it malfunctioned or whether a child would be able to pull the trigger.

Collins had convictions for possession of cocaine and obstruction of an officer, police records show.
