Yvonne Ervin of Snellville, Georgia called 911 Saturday morning to report that she and her husband Zachary were being attacked by their sons in their home.
"(Yvonne Ervin) stated to our 911 operator that her sons were trying to kill her and her husband," Gwinnett County Police Sgt. Rich Long told CNN.
"(Yvonne Ervin) told the 911 operator that (her husband) had distracted the sons and that she was able to call," said Long. "That was probably the life-saving move from this event."
Yvonne Ervin, "also had blunt force trauma but not as severe as the father," said Long.
The sons had also, "introduced natural gas into the house," as they plotted to burn the home down, according to authorities.
The two sons remain behind bars and each have been charged with two counts of felony aggravated assault and two felony counts of first degree arson.
"There is no official motive at this point, but there has to be something more to this. I'm sure they didn't just wake up and decide to kill their parents yesterday," Long said.
