The Georgia mother accused of stabbing her husband and four of their five children to death this week smiled in court on Friday and gave a thumbs-up to photographers as she appeared in front of a judge for the first time since Thursday's alleged attack.
Martinez was given no bond and declined a court-appointed attorney, explaining through an interpreter that she would be represented by "the people".
Gwinnett County police and firefighters responded to a 911 call from inside the home in Loganville, Ga., where they found what one police official described as a "horrendous" scene: five bodies - one of the victims not yet 2 years old - along with another child who was badly injured.
Police Cpl. Michele Pihera told reporters Thursday that Martinez was "quickly taken into custody", according to ABC affiliate WSB.More news: Wimbledon safety row after shocking injury to Bethanie Mattek-Sands
She is also being held for U.S. immigration and customs violations.
Some 12 hours after that call, police believe, Martinez, 33, embarked on an unspeakable rampage, killing four of her children and their father, one by one. Police said Romero and Isabel Martinez were married.
Martinez appeared in court Friday to face five counts of murder, five counts of malice murder and six counts of aggravated assault. According to a GoFundMe page set up to help pay for funerals and medical costs, Diana has gone through surgery and will likely remain in the hospital for a few weeks before starting physical therapy. Their father was Martin Romero.
Meanwhile, police have said that the mother was cooperating in the investigation but has yet to offer any explanation for the killings.

Authorities say that they think their detectives will be able to "get into her psyche and figure out her motive".
Police have not yet released why Martinez allegedly killed her family.
Neighbors said Martinez was distraught over her father's death, but otherwise seemed perfectly normal.
Pedro Ramirez said Martinez and her family seemed to be happy and Martinez, usually the life of the party. "She was good, went to our church last weekend".More news: U.S. bombers fly over South China Sea to assert right
