Debbie Hixon, wife of Chris Hixon, a 49-year-old coach killed in the school shooting, addressed Nikolas Cruz directly on Tuesday morning.

She said her husband “was stolen from us by an unimaginable act that you planned and executed.”

“You did not receive the justice that you deserve,” she said. “You were given a gift -- a gift of grace and mercy. Something you did not show to any of your victims. I wish nothing for you today. After today I don’t care what happens to you … you’ll be a number.”

“Today we close this chapter,” Hixon continued. She said she’ll choose to remember all of the positive memories of her husband, instead of the “darkness.”

Chris Hixon’s son, Thomas Hixon, said to Cruz, "You're not a disturbed or broken person," but instead "lacks character."

By killing his father, Thomas Hixon said Cruz "weakened a family, a community and generations of young adults by taking their strongest advocate out of their corner."

He called Cruz "living proof that evil does exist in our world."

Hours after the sentence was announced on Oct. 13, Manuel Oliver, whose 17-year-old son, Joaquin, was among the victims, told ABC News Live he had hoped for the death penalty.

"Even the death penalty was not enough for me," he said. "The way that Joaquin died ... the amount of suffering and pain, the shooter will have never received that punishment."

His wife, Patricia Oliver, told ABC News she feels enraged by the jury’s decision, and said her son did not get justice.

To jurors who voted against the death penalty, she said, "They have to live with that in their conscience. Life is about karma. They will remember what they did when the time comes."

Fred Guttenberg, whose 14-year-old daughter, Jaime, was killed in the massacre, said he was “stunned” by the verdict.

"I could not be more disappointed," he told reporters on Oct. 13. "I don't know how this jury came to the conclusions that they did."

"This decision today only makes it more likely that the next mass shooting will be attempted," he said.

Guttenberg said he thinks the next mass shooter is planning his attack now, and "that person now believes that they can get away with it."

"There are 17 victims that did not receive justice today,” Guttenberg said. "This jury failed our families today. But I will tell you: The monster is gonna go to prison, and in prison, I hope and pray, he receives the kind of mercy from prisoners that he showed to my daughter and the 16 others. … He will die in prison, and I will be waiting to read that news on that."

Bree Wikander was overcome with emotion as she spoke on behalf of her son, Ben, who was shot three times, including in the back. Ben was 17 at the time and suffered extensive injuries.

“One of Ben’s trauma surgeons … once said to us, Ben sustained injuries similar to what a soldier would in combat,” she said.

“To this day he is still recovering,” Bree Wikander said. “You will never understand the pain that he has gone through. His life and the lives of our entire family have changed forever both physically and mentally.”

Ben’s father, Eric Wikander, said he hopes Cruz has a “painful existence” in prison, adding that it would still be “a fraction of what Ben endured.”
