She also is accused of seriously injured another child, Diana Romero, 9, at her home, according to Gwinnett Daily Post.
Thorpe told Martinez she will have a preliminary hearing on July 20. "Alright?" But the judge tried to have Martinez reconsider her decision to not have an attorney representing her, ".and I doubt that you are well equipped to handle that on your own, but that's your decision.
"She says her dad passed away months ago", said Perez.
Flowers and stuffed toys are left on the doorstep of the home where four children and their father were stabbed to death..
"For me, the hope and the attorneys are always going to be the people and my faith".
When asked why did not want legal representation, she said that she was there to represent people who are "humble and hardworking; people who suffer" and that God would take care of her.
U.S. Customs and Immigration Enforcement spokesman Bryan Cox said in an email Friday that Maria Isabel Garduno-Martinez, whom local law enforcement identified as Isabel Martinez, is from Mexico and entered the U.S. illegally. Deon Washington said Thursday that Martinez is the "primary suspect", adding investigators are "not searching for anyone else".
But Martinez continued to shake her head.
Her behavior in court was weird and erratic as she smiled to the media and gave two thumbs-up to the cameras.
Police believe the 911 call reporting the stabbings was made by Martinez. A fifth child also was stabbed but survived.
Authorities in Georgia charged 33-year-old Isabel Martinez on Thursday afternoon with five counts of malice murder, five counts of murder and six counts of aggravated assault, hours after police said she called 911 to report the killings from the home the family shared outside Atlanta. As of Thursday evening, she was in stable, but serious condition in Children's Hospital of Atlanta.
Gwinnett County Magistrate Judge Michael Thorpe advised her to stop performing for the cameras. The children who are deceased were aged 2 to 10. The relative, identified as Hallie Romero, of Loganville, said Diana is expected to be in the hospital for two to three weeks.
Some neighbors in the small, largely Hispanic neighborhood in Loganville, about 30 miles (48 kilometers) east of Atlanta, said the Spanish-speaking family had moved to the community recently.
