State crime lab officials conducted an autopsy Monday on a suspect who died following an apparent attempt to hide cocaine by swallowing it.

Autopsy results from the Georgia Bureau of Investigation crime lab in Savannah were not available Monday afternoon on the exact reasons why

Kelly Anderson, 33, of Hardeeville, S.C., died at Memorial University Medical Center on Saturday night. But Anderson had been in custody at the Effingham County Jail after being arrested for possession of cocaine and drug paraphernalia.

Anderson was a passenger in a pickup that was stopped by an Effingham County Sheriff’s deputy just after midnight last Thursday. Anderson was found to be carrying cocaine and a large amount of cash, according to investigators.

In the back of the patrol car, Anderson began acting strangely and began putting something in his mouth as he was being taken to the Effingham County Jail. The deputy pulled over at I-95 and Highway 21 and called for EMS. Emergency medical technicians and the deputy struggled with Anderson, eventually removing a packet of cocaine from his mouth.

After he was taken to Memorial, he was released back to the Effingham Sheriff’s Office and began the trip back to jail. But during his booking, he became unresponsive, deputies said, and was returned to Memorial.

Because Anderson fell ill while he was in Effingham Sheriff’s Office custody, the ECSO asked the GBI to conduct a death investigation.
