He was scheduled Monday to undergo his third surgery related to the bite, according to his sister.
Moody suffered a heart attack Thursday, she said. On Friday, he made bond on the murder charge despite missing a hearing because of his hospitalization.
The hospital where Moody is being treated is not being
disclosed, at the family’s request.
The infection has gained national attention after it claimed the leg, hand and foot of Georgia graduate student Aimee Copeland, who is still battling for her life at Augusta’s Joseph M. Still Burn Center after cutting her leg during a May 1 accident.
Moody was charged with murder and possession of a firearm during the commission of a crime after police were dispatched May 28 to his Red Bird Road home.
Officers said they found his 23-year-old son, Rocky Moody, dead from a gunshot wound to the chest.
An incident report indicated that an argument between the father and son escalated and turned physical.
After Robert Moody was assaulted, police said, he grabbed a .30-30 rifle and hid in the closet.
When Rocky Moody opened the closet door, his father fired the rifle once, hitting him in the chest.
Police are unsure how much time passed between the assault and the shooting, but authorities believe Rocky Moody left the residence and then returned.
An incident report indicated it was approximately 30 minutes between the initial argument and when Rocky Moody was pronounced dead.
Richmond County sheriff’s Lt. Blaise Dresser said the father was charged with murder because the investigation revealed he had enough time to seek help from authorities but chose not to call 911.
On Wednesday, Moody was taken to a hospital to be treated for an infection believed to come from several bites he received during the assault.
Most infections of that sort are fairly mild, but in anywhere from 9,000 to 11,500 cases a year, the bacteria get into the bloodstream through a sore or a cut and become invasive, according to the U.S. Centers for Disease Control and Prevention.
In 6 to 7 percent of those cases, the infection attacks the lining of flesh and muscles and becomes necrotizing fasciitis, according to the CDC.
Though it can be treated with antibiotics, surgery to remove infected tissue sometimes becomes necessary.
About 25 percent of the cases are fatal, according to the CDC.
