Max Schachter, whose 14-year-old son, Alex, was killed, noted on Tuesday that, when families gave statements earlier during the penalty phase trial, they were prohibited from talking about Nikolas Cruz, the crime “and the punishment that he deserves.”

Schachter accused Cruz’s defense attorneys of “making the mental health crisis in America worse by misrepresenting what actually happened to the Parkland murderer.”

“The defense, in their closing argument, said if he had just had the proper diagnosis, things would be different,” Schacter said. “Nothing would’ve changed. … He was on medicine after medicine … and he still wants to kill.”

Cruz grew up “in a loving home” with a mother who tried to help him, Schachter said.

“He had well over 200 individual sessions with mental health professionals. … They tried everything, they couldn’t have given him more services,” Schachter continued.

“But you can’t fix evil,” he said.

“He hunted down innocent children and staff, terrified then tortured them, blew their heads apart like a water balloon and enjoyed it,” Schachter said.

He said Cruz “does not deserve to live amongst us.”

Schachter said, in prison, Cruz “gets to receive phone calls, boxes of fan mail. He gets to fall in love and get married. He gets a tablet to email and text people. He gets to receive visitors. He gets to watch TV … and even get a college degree.”

Schachter noted that today marks his birthday. He said his birthday wish each year will be for Cruz to “suffer a painful, painful violent death.”

After Schachter spoke, Cruz’s attorney said families are sending a bad message by attacking defense lawyers, jurors and the judicial system.

Meghan Petty, sister of 14-year-old victim Alaina Petty, said she feels “betrayed by our justice system” with the jury rejecting the death penalty, and feels vulnerable sharing her pain with the public.

Alaina was shot multiple times, including through the heart, she said. Alaina died scared on a classroom floor, trying to hide behind a desk, she said.

“This entire ordeal has pushed me to my emotional, physical and mental limits. It will continue to do so for the rest of my life, even more so now that he has escaped being punished to the fullest extent of the law,” Petty said.

She called Nikolas Cruz a “remorseless monster who deserves no mercy.”

“This incredible darkness that he has within him -- which has been labeled here as mental illness -- is something that should be considered unacceptable and intolerable,” Petty said. But she said his life sentence sends the message to future shooters that “if one stretches the truth, they can get away with not only murder, but mass murder.”

“What we’ve been told here is 17 lives are worth nothing if you can make enough excuses for your actions,” she said.

Petty noted that she and Cruz are the same age.

“I could sit here and complain, as he has, that I’ve had a hard life. I was bullied in school. I’ve lost 15 family members and loved ones since I turned 9 to sickness, suicide, accident and now murder. Not once have I turned to ever hurting others … because I’m not a coward and I’m not weak,” she said.

"I will never get to say goodbye to her," she said of her sister. "She's never going to go to college, get a job, get married ... or even breathe again. But he'll be able to draw breath."

On the day of the shooting, Ines Hixon, daughter-in-law of slain coach Chris Hixon, was deployed on a U.S. aircraft carrier off the coast of Iran.

“He would’ve given the shirt off his back. He was a courageous, loving and wonderful man. And I never got the chance to tell him that,” she said through tears.

Victim’s daughter-in-law calls Parkland shooter a 'domestic terrorist'

Ines Hixon was the daughter-in-law of Chris Hixon, the athletic director and wrestling coach at Marjory Stoneman Douglas High School, who was killed in the attack.

“As a service member, I took an oath to defend the Constitution of the United States against all enemies foreign and domestic. And to the defendant, that’s exactly what I view you as -- a domestic terrorist,” Ines Hixon said. “I wish no peace for you. I wish nothing but pain. And I hope that every breath you take, you remember that’s a breath you stole.”

After Ines Hixon spoke, Judge Elizabeth Scherer called her a “hero,” adding that her “beautiful family” has “made such an impression on this court.”

“I thank you for your service and bravery,” the judge added.

Patricia Oliver, whose 17-year-old son, Joaquin, was among the victims, said in an impassioned statement, if this case “doesn’t deserve the death penalty, what does?”

“You had in your head enjoyment,” she said directly to Nikolas Cruz. “Listen to me, defendant -- enjoyment while killing my son, Joaquin Oliver, and coming back to him to blow his brain out.”

“Your living hell is about to get started,” she said. “Joaquin is a legend for what he is and for what he will be. Nice, kind, humble. And you will remember every single day of your life about what Joaquin is.”
