Four young children and their father have been found apparently stabbed to death in a home outside Atlanta, and police said the mother - a suspect in the case - was the one who called 911 to report the killings.
A fifth child, a girl, survived and was taken to hospital with injuries described as serious, police said.
The woman was detained by police after the bodies were found inside the home in Loganville, Gwinnett County police Corporal Michele Pihera told reporters at the scene. Police later issued a statement calling the mother a "suspect" in the deaths, although no charges have been filed.
"She was quickly taken into custody and right now she's at Gwinnett County Police Headquarters being interviewed," Cpl Pihera said. Police have not said whether she was injured.
"Right now we believe we have everybody involved in this crime," Cpl Pihera said, adding that she does not want people in the community to think that a dangerous person is at large.
Cpl Pihera told The Atlanta Journal-Constitution that the mother was speaking Spanish in the 911 call, which initially made it difficult for operators to communicate with her.
Early indications are that a knife was used to attack the five, though a medical examiner will make the final determination about the cause of death, she said.
The injured girl was still alive late on Thursday morning, police said in a brief update on the case.
The four children killed appear to be under age 10, Cpl Pihera said. Their father was in his mid-30s, she said.
Police initially said in a statement that a woman inside the home called police at 4.47am local time on Thursday to report a stabbing and officers answering the call found the five bodies inside.
Police said a motive was not immediately known.
