Georgia News Network reports the fourth death was reported over the weekend after authorities found the body of a 54-year-old homeless man who'd been reported missing.
A medical examiner will decide whether it was exposure.
This comes on the heels of the deaths in Dacula of two teens who fell through the ice Saturday (see separate story) and the Thursday death of an Acworth woman whose car slid on the ice.
