Some neighbors in the small, largely Hispanic neighborhood in Loganville, about 30 miles (48 kilometers) east of Atlanta, said they had no clue anything was amiss in the home until police mobbed the scene Thursday morning. The neighbors said the Spanish-speaking family had moved to the community recently, and their children seemed happy playing with other neighborhood kids.
Victoria Nievs said Martinez had recently suffered the death of her father.
Gwinnett County Police Cpl. Michele Pihera confirmed that the 911 call came from a woman who was inside the home at 4:47 a.m. Thursday to report a stabbing. Police believe Martinez made that call.
Pihera said the caller was speaking Spanish, which initially made it difficult for 911 operators to communicate with her. The county sheriff’s office said Martinez is on a hold for U.S. Immigration and Customs Enforcement.
The hospitalized girl, Diana Romero, was in serious but stable condition Thursday evening, police said.
The four children killed were identified as Isabela Martinez, 10; Dacota Romero, 7; Dillan Romero, 4; and Axel Romero, 2. Their slain father was Martin Romero, 33, Pihera said. Police said Romero and Isabel Martinez were married.
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.
