Nikolas Cruz, the 23-year-old gunman who carried out the Marjory Stoneman Douglas High School shooting in Parkland, Fl. in Feb. 2018, plead guilty to 17 counts of murder and 17 counts of attempted murder on Wednesday.

According to CNN, Nikolas Cruz faces a minimum of life in prison and a maximum possibility of receiving the death penalty, which under certain circumstances is legal in the state of Florida.

Giving a short speech in the courthouse on Wednesday, Cruz stated that, “I am very sorry for what I did, and I have to live with it every day.”

“If I were to get a second chance, I would do everything in my power to try to help others,” he said. “I have to live with this every day, and it brings me nightmares and I can’t live with myself sometimes, but I try to push through because I know that’s what you guys would want me to do.”

After the guilty phase, death penalty cases in Florida now move on to the “penalty phase,” where the state now decides if Cruz should face death for the horrifying 2018 school massacre.

According to the State Attorney’s Office, there was no negotiation that if he pleaded guilty and showed remorse that he would save himself from the death penalty. “If he pleads guilty,” a statement read, “there would still be a penalty phase.”

Judge Scherer read the counts to Cruz, reminding him of the charges and that if he plead guilty, his “best case scenario” would be life in prison.

“Life in prison means the term of your life,” Judge Scherer said. “It means you will not come out until you are no longer alive.”

According to NBC News, Cruz replied that he understood and replied “guilty” to all 17 counts read out loud by the judge.

“I find that you are alert and intelligent, that you have made an informed decision with the advice of counsel,” Judge Scherer stated. “I find that you have made this decision after going over and understanding all of your rights and that you are knowingly, voluntarily, and intelligently waiving each and every one of the rights that I went over with you today.”

Witnesses in the courtroom on Wednesday included Anthony Borges, who survived after he was one of the students shot by Nikolas Cruz; Tony Montalto, whose daughter Gina was killed, Tom and Gena Hoyer, whose son Luke was killed; and Debi Hixson, whose husband Chris, the athletic director at Marjory Stoneman Douglas, was killed, CBS Miami reported.

The Parkland shooting, which occurred three and a half years ago, was the deadliest high school shooting in US history. Cruz had previously plead “not guilty” to premeditated murder, though he later confessed to police once video surfaced of him describing the eventual crime.

In a harrowing cellphone video, Nikolas Cruz bragged about the shooting, excited that he would become notorious for the massacre.

“It’s gonna be a big event,” Cruz said in the video. “When you see me on the news you’ll all know who I am. You’re all going to die, can’t wait.”

Seemingly shot the same day as the shooting, Cruz boasted that his goal was to shoot “at least 20 people.” He showed little to no empathy or remorse for the acts he was about to commit, and even laughed and took pleasure in describing his plans.

Fred Guttenberg, whose daughter Jaime was one of the victims, told The Sun Sentinel that he read the transcript but could not bring himself to view the footage.

“I already know what he did,” Guttenberg said. “He’s evil. Repulsive. He deserves to be dead… It’s a level of thought that I can’t comprehend. It looks, from the words, like the kid had joy. I don’t want to see the delight he took in planning the murders of our children.”
