Isabel Martinez allegedly stabbed her four young kids to death.
A Georgia woman stands accused in the grisly murder of her family, but footage from her court appearance shows her with no apparent care in the world.
A smiling Isabel Martinez was told by a Gwinnett County judge to stop "playing to the camera" after WGCL reported that the 31-year-old knelt in front of the lenses and was warned to sit back in the bench.

At one point, Martinez even gave a "thumbs up" to the camera during the bizarre scene, which unfolded Friday morning, just a day after the mother of five was named the only suspect in the fatal stabbings of her husband and four young children.
A judge charged Martinez with six felony counts of aggravated assault and five counts of murder, as well as five counts of malice murder.
Martinez was given no bond and declined a court appointed attorney, explaining through an interpreter that she would be represented by "the people."
"We are all God's people" and God loves us all," she later said.
The children killed were identified as Isabela Martinez, 10, Dacota Romero, 7, Axel Romero, 2, and 4-year-old Dillan Martin-Romero.
A fifth child, 9-year-old Diana Romero, was also stabbed but was found alive and taken to the hospital. She remains in serious condition.
"What prompts a person to take the life of such innocent children and her spouse is something we may never understand," the Gwinnett County police said in a statement. "This is a horrendous crime not only for the victims but for the extended family, neighborhood and community."

Police also asked that the surviving daughter remain in the public's thoughts.
"We continue to pray for Diana's recovery both physically and emotionally as she learns about what happened to her," the statement said.
