GIFFORD, Fla. (AP) — An off-duty Indian River County sheriff's deputy was fatally shot outside a relative's home.

The sheriff's office says Deputy Garry Chambliss was killed Friday night after gunshots were fired as he and other relatives were standing near a road.

Chambliss yelled for people to "get low," and then fell with a gunshot wound to his chest. He was taken to a hospital, where he died.

Deputies arrested 21-year-old Makhail Chambliss and charged him with discharging a firearm from a car. He is being held without bond. Multiple news agencies reported he is related to the slain deputy. Investigators were searching for a second suspect on Saturday.

Deputy Chambliss had served on the department for 27 years and was less than three years away from retirement.
