Nikolas Cruz will face either the death penalty or life without parole.

The sentencing trial has nearly concluded for Nikolas Cruz, perpetrator of the 2018 mass shooting at Marjory Stoneman Douglas High School in Parkland, Florida. Cruz has pled guilty to all charges brought against him, including 17 counts of murder and 17 counts of attempted murder. Due to his guilty plead, the regular trial was skipped, and the defense and prosecution have debated over Cruz’s potential sentence.

The 12-person jury in the case is set to begin their deliberations today, with the options on the table being either the death penalty or a life prison sentence without parole. In order to enact the death penalty, the jurors’ votes must be unanimous, otherwise the sentence will default to the life sentence.

Prior to this, the defense and prosecution offered their closing arguments on the case yesterday. The prosecution’s case was that the attack on the school was deliberate and premeditated, and should be treated as such. “What he wanted to do, what his plan was and what he did, was to murder children at school and their caretakers,” said lead prosecutor Michael Satz. “The appropriate sentence for Nikolas Cruz is the death penalty.”

The defense countered that Cruz was not entirely responsible for his actions due to familial mistreatment and various mental disorders. Defense attorney Melisa McNeill called Cruz “a brain damaged, broken, mentally ill person, through no fault of his own.”

“And in a civilized humane society, do we kill brain damaged, mentally ill, broken people?” McNeill asked. “Do we? I hope not.”
