Nikolas Cruz’s motive for the Parkland shooting was not one thing. Across his own recorded statements, years of documented planning, and months of penalty-phase testimony, prosecutors and defense experts described a young man driven by a desire for infamy, deep resentment tied to isolation and a recent breakup, hateful racist views, and a lifelong pattern of behavioral disturbance that his lawyers traced to prenatal substance exposure. He killed 17 people and wounded 17 others at Marjory Stoneman Douglas High School on February 14, 2018, pleaded guilty to first-degree murder in October 2021, and was sentenced to life in prison without parole in November 2022.
What Cruz Said He Wanted
In cellphone videos recorded before the attack and later released by the Broward County State Attorney’s Office, Cruz stated his goals in his own words. “I’m going to be the next school shooter of 2018,” he said, adding that his aim was to kill “at least 20 people with an AR-15.” He told the camera, “when you see me on the news, you’ll all know who I am.”1CBS 12.

He picked the date for a reason. Cruz told forensic psychiatrist Dr. Charles Scott, a prosecution expert, that he chose Valentine’s Day because “he has no one to love and love him.”3WPBF. Florida Parkland School Shooter Trial In a jailhouse interview with a psychologist he was more direct: “I didn’t like Valentine’s Day and I wanted to ruin it for everyone.” Asked whether he meant for the families of victims, he specified, “No, for the school,” saying the holiday would never be celebrated there again.4WLRN.

During his post-arrest interrogation with Broward Sheriff’s Detective John Curcio, Cruz offered a different explanation. He described a “demon” voice that told him to “burn, kill, destroy,” and said the voice had instructed him to hurt people the night before the shooting and to buy his AR-15. In the same interview, though, he told Curcio he had chosen the rifle because it was “cool looking.” When Curcio pressed him that the demon story sounded like an excuse, Cruz insisted it was real. His defense attorneys later argued the interrogation was structured to head off a possible insanity defense, and noted that Cruz asked for a psychologist during the interview and was refused.5NBC Miami.

A Plan Built Over Years
The attack was not impulsive. Dr. Scott testified that Cruz told him he began contemplating mass murder in middle school, inspired by the 1999 Columbine High School massacre.7Fox 13 News. Parkland Shooter Trial: Nikolas Cruz Contemplated School Massacre for Years Over the following years he studied the 2007 Virginia Tech shooting and the 2012 Aurora movie theater shooting, telling Scott he researched them to “learn their methods and mistakes.”3WPBF. Florida Parkland School Shooter Trial
From that research he developed specific tactics: how to maneuver around corners, maintain distance from victims, and finish quickly. He observed that in earlier school shootings “the police didn’t do anything” and estimated he would need about 20 minutes.7Fox 13 News.

His search history matched the pattern. A Broward County Sheriff’s detective testified that Cruz had looked up maps of Marjory Stoneman Douglas roughly two weeks before the attack, searched “how long does it take for a cop to show up at a school shooting” the day before, and searched the school’s name on the morning of February 14.8CNN. Nikolas Cruz Social Media and Online Searches Prosecutors called the massacre “calculated and premeditated.”
Racist Ideology and the Instagram Chat
Cruz held explicitly racist, anti-Semitic, and homophobic views, and he expressed them repeatedly in the months leading up to the shooting. Starting around August 2017 he participated in a private Instagram group chat he had named “Murica great,” where he posted hundreds of hateful messages. He wrote that he hated “jews, ni**ers, immigrants,” said he hated Black people “simply because they were black,” and claimed Jews “wanted to destroy the world.” Of LGBTQ+ people he wrote, “Shoot them in the back of head.” He discussed killing Mexican people and keeping Black people “in chains.”9CNN. School Shooter Instagram Group In the same chat he wrote, “I think I am going to kill people,” and asked whether body armor was legal to wear to school, answering his own question when pressed: “school shooters.”10The Forward.

The physical evidence matched. Federal law enforcement confirmed Cruz had etched swastikas onto the ammunition magazines he brought to the school, and he left roughly 180 rounds of swastika-marked ammunition at the scene after firing about 150 rounds.11CBS News.

An early claim that Cruz belonged to an organized white nationalist group did not hold up. Jordan Jereb, who led a militia called the Republic of Florida, initially said Cruz had trained with the group, then walked the claim back, and the Leon County Sheriff’s Office confirmed “no known ties.” Investigators traced the story to a coordinated hoax on 4chan, and CNN’s review of Cruz’s Instagram chat likewise found no link to any organized movement.13Snopes.

The Breakup That “Spiraled”
Dr. Scott testified that Cruz’s behavior began to “spiral” after a breakup roughly six months before the shooting.7Fox 13 News. Parkland Shooter Trial: Nikolas Cruz Contemplated School Massacre for Years Reporting on the relationship fills in the picture. Cruz had dated a student at another school, and friends described the relationship as abusive, prompting the girl to end it. After the breakup, Cruz used her Instagram account to send threats, including telling one acquaintance, “I’m going to get you and I’m going to kill you because you took this person away from me. I’m going to kill your family.”14BuzzFeed News. Cruz
He also targeted a Stoneman Douglas student, Enea Sabadini, who began dating his ex-girlfriend, messaging him, “I am going to enjoy seeing you down on the grass” and “iam going to shoot you dead.” In September 2016, two fights broke out between the two at the school, one involving Cruz trying to stab Sabadini with pencils. Students reported the threats and their worry about Cruz’s access to weapons to school security.14BuzzFeed News. Cruz Cruz was expelled from Stoneman Douglas in early 2017.
A Childhood His Lawyers Called “Broken”
Cruz was born on September 24, 1998, to Brenda Woodard, who struggled with addiction and had 28 arrests over her lifetime.15Miami Herald. Nikolas Cruz Family Background Woodard was arrested for purchasing crack cocaine while pregnant with him.16WLRN. Parkland Shooter’s Birth Mom Had a Violent Criminal Past She gave him up at birth. Lynda and Roger Cruz adopted him in Parkland. Woodard died of cancer in 2021 and never testified.17The Independent. Nikolas Cruz Birth Mother Brenda Woodard
The behavioral signs came early. At age four, a special-needs preschool teacher described him as aggressive and non-communicative, hissing, scratching, and pouncing on other children in what she called “animal fantasies.”18NBC News. Nikolas Cruz’s Brain Irretrievably Broken He began special education at six. Roger Cruz died when Nikolas was five, and his defense argued Lynda Cruz then struggled with depression and financial hardship. He was removed from preschool for hurting other children, later spent about two years at Cross Creek School for students with emotional and behavioral disorders, and received years of mental health treatment.19CBS News. Parkland School Shooter’s Brain Exams The defense also raised bullying, alleged sexual abuse by a “trusted peer,” self-harm, and animal abuse.
He was expelled from Stoneman Douglas in early 2017 for fighting and for carrying bullets in his backpack. A school monitor reportedly predicted at the time, “That kid is going to come back and shoot this school up.” Lynda Cruz died in November 2017, less than three months before the shooting. His defense team argued her death “uprooted any stability in his life.” Law enforcement had by then visited the Cruz home more than 40 times.20CNN. Nikolas Cruz Trial Defense
Damaged Brain or Deliberate Choice
The penalty trial turned on a single question about cause: was Cruz’s violence the product of a brain damaged in the womb, or of a functioning mind that chose cruelty?
The defense, led by public defender Melisa McNeill, argued his brain was “irretrievably broken” and that he had been “poisoned in the womb.” Dr. Paul Connor, a clinical neuropsychologist, testified that Cruz showed signs of fetal alcohol syndrome, citing 50 years of research on prenatal alcohol exposure.21NBC Miami. Defense Expert Testifies About Fetal Alcohol Syndrome’s Effect on Parkland School Shooter The defense also tried to introduce quantitative EEG brain-scan results, which a prosecution expert called “worthless.”19CBS News. Parkland School Shooter’s Brain Exams
The state’s experts rejected that framing. Dr. Scott diagnosed Cruz with antisocial personality disorder and concluded he could control his behavior but chose not to out of disregard for others, pointing to a 14-month stretch as a store cashier without incident and his performance in alternative education as proof he could conform when he wanted.7Fox 13 News. Parkland Shooter Trial: Nikolas Cruz Contemplated School Massacre for Years Dr. Robert Denney, a clinical neuropsychologist for the prosecution, testified that Cruz’s test results did not meet the diagnostic criteria for fetal alcohol spectrum disorder and that Cruz had deliberately performed poorly on cognitive testing, scoring “perfectly normal” on a sophisticated executive-function task.22CBS 12.

How the Jury Weighed the Question
The jury never had to settle the motive question with a single answer, but its vote showed the split. On October 13, 2022, all 12 jurors found the state had proven aggravating circumstances on every count. Three concluded the mitigating evidence, much of it about Cruz’s background and brain, outweighed those aggravators. Under Florida law at the time, a death sentence required unanimity, so Cruz received life without parole.23Death Penalty Information Center. Non-Unanimous Florida Jury Sentences Nikolas Cruz to Life Without Parole On November 2, 2022, Broward Circuit Judge Elizabeth Scherer imposed consecutive life sentences on each murder count and on the attempted murder counts.24CNN.

Cruz himself gave more than one account of what drove him, from a “demon voice” in his interrogation to a stated desire to ruin Valentine’s Day and to be seen on the news. His planning stretched back to middle school. His hatred was on the page and on his magazines. The people who examined him closest disagreed on why. That combination, rather than a single cause, is what the record shows.
