"My family and I have suffered emotionally for many years," said Maribel Marcial, a sister of one of the victims.
David Marcial, 10, was riding his bike in front of his house in South Los Angeles when the killers opened fire. His 22-year-old uncle Larry Marcial was also killed, along with their neighbor, 17-year-old Luis Cervantes.
"At the end of the day, they weren't doing anything out of the ordinary. They were just at home, playing," she said.
One of the men convicted in the killings was sentenced to death Friday. But in court, Ryan Moore lashed out at prosecutors, claiming he been wrongfully convicted.
"Those who said that they saw me, or thought they saw me, are incorrect," Moore told the judge.
After the judge told Moore he needed to reflect on taking responsibility, Moore became angrier.
"Responsibility for what?" Moore said, interrupting the judge. "I didn't stand over those kids and kill no kids. I did not touch not one individual. I've never harmed not one child."
Moore's outburst came after several of the victim's family members read heartbreaking testimonials about their lost loved ones.
"I've tried to find the words to tell you how the boys, David, Larry and Luis's murders have impacted our lives, but there are no adequate words to describe the pain, anger and despair that we all have felt," said Isis Clark
But the statements seemed to have little impact on the 38-year-old Moore, who eventually had to be removed from the courtroom.
Moore and his accomplice, Charles Ray Smith, were convicted on three counts of first-degree murder. Smith will be sentenced later this year. Moore's death sentence will be automatically appealed in May, but he was sent immediately Friday to San Quentin, where he is sitting on death row.
Marcial said she doesn't care if Moore is put to death, she's just glad that he's behind bars.
"He's going to have to live with realization of what he did, like we're gonna have to live without having David or Larry or Luis around," Maribel Marcial said.
