A Vicksburg boy injured Saturday in a fire at his home has been released from a Georgia burn center, and three Vicksburg residents injured in a fire at their Oak Street home on March 7 remain in hospitals.

The condition of Barbara Evans, 57, was upgraded to good at Crossgates River Oaks Hospital in Brandon, hospital spokesman Missy Odom said.

Evans’ grandsons, Robert Evans, 4, and Stephon Evans, 8, remain at  Joseph M. Still Burn Center in Augusta, Ga. Robert’s condition was downgraded from serious to critical, hospital spokesman Olena Scarboro said, while Stephon’s was upgraded to fair from serious.

All three were injured after a dislodged electric heater at their home at 2314 Oak St., set the house ablaze. It was among three homes destroyed in the fire.

Released on Thursday from the Georgia burn center was Nathaniel Ashley, 8, who was injured Saturday after he threw an aerosol can into a fire pit and the can exploded in his face.

The son of Tina and Staff Sgt. Roger Ashley was back home after five days of treatment to his face, neck, hands and upper chest.

“He has been a real trooper,” his mother said.

Nathaniel’s father, who had been in Afghanistan deployed with the U.S. Army Corps of Engineers 412th Theater Engineer Command, is home indefinitely.
