A tragic shooting in northwest Georgia last weekend resulted in the death of an off-duty police officer, raising the total number of fatalities to four.

Authorities confirmed that 52-year-old Officer Charles Dunn from Chickamauga died days after being critically injured in the attack. He was a family friend of the victims and was inside the home when 54-year-old Russell David Payne from Marietta began his violent assault.

During the incident, Payne fatally shot his estranged wife, 54-year-old Jacklyn D. Payne, and her father, 79-year-old Eugene “Jack” Denny. Afterwards, Payne took his own life at the scene. The violence started with a 911 call from the residence around 7 p. m. Dunn was remembered as a “true hero” who donated his organs after his passing, known for his kindness and love for people and animals.
