ATLANTA — Glynn County is doubling the reward money being offered for information leading to an arrest and conviction in the death of one of its commissioners.

Tom Sublett’s body was found last week in the Frederica River near St. Simons Island after he failed to return home from an evening poker game with friends. An autopsy determined that Sublett was shot in his head before drowning, but the Georgia Bureau of Investigation has not determined whether his death is a homicide.

“There’s no new information to report at this time. I wish there were, but there’s not,” Georgia Bureau of Investigation Special Agent in Charge Michael McDaniel said Friday.

The Glynn County Police Department is offering $25,000 for information in the case. On Thursday, county commissioners unanimously voted to match that offer, according to Glynn County spokeswoman Candice Temple.

Temple said each of the commissioners took time to reflect on Sublett’s death and say kind words about him during what would have been his last meeting.
