Both boys were found unconscious inside the house after a relative called 911 just before 9 a.m., police Detective Kelly Gobely said. One of the boys was the son of the slain woman, who police said was widowed. One of the daughters was an adult, police said.
"I don't have their manner of death," Gobely said. "I know the medical examiner's office is here. We will have to wait for them to give us word."
The two boys were taken to Children's Healthcare of Atlanta at Scottish Rite in Atlanta, about 20 miles away, Gobely said. She had no word on their conditions.
One boy was taken by helicopter to the hospital, reported the Atlanta Journal-Constitution. Sgt. Dana Pierce, a spokesman for Cobb police, which is assisting Powder Springs police, said the child had blunt force trauma, according to the Journal-Constitution. Gobely said a second boy was not a family member, the Journal-Constitution reports.
Cobb County police spokesman Dana Pierce said officers were investigating the deaths at the Powder Springs home as a triple homicide. Police said the home is in a quiet neighborhood and everyone who lived in the house had been accounted for.
Jermaine Goddard, a 16-year-old neighbor, said one of the girls who lived in the home was his classmate.
"She was just a nice kid," he said. He said he often saw the girl walking a younger brother to the school bus stop in the mornings.
Gwen Mason, who had lived next door until Tuesday, said Jane Kuria, 47, and her three children lived in the home at 4789 Country Cove Way, reported the Atlanta Journal-Constitution.
Mason said Kuria was a nurse and that she had two daughters and a son. She said the children were: Isabella, who was about 19 and attended college, Annabell or Wambui, a McEachern High School sophomore; and Jeremy, 7.
She said Kuria told her the family had moved from Africa after Kuria's husband died.
Cobb County real estate records indicate Kuria bought the home in 2005. Mason said she moved next door last year and used to keep an eye on Kuria's children after school.
"She told me she loved living in her house," said Mason. "She used to live in an apartment and loved having the house. She said she had to work a couple of jobs because her husband had passed and she needed the house for the children."
