The '''Parkland high school shooting''' was a mass shooting perpetrated by 19-year-old '''Nikolas Cruz''' on February 14, 2018.<ref name="WikipediaParkland">{{cite web |url=https://en.wikipedia.org/wiki/Parkland_high_school_shooting |title=Parkland high school shooting - Wikipedia |website=Wikipedia |access-date=2025-08-11}}</ref> The case presents a tragic confluence of profound mental and behavioral health issues, a documented history of escalating violence, and a series of systemic failures that culminated in one of the deadliest school shootings in American history.<ref name="WaPoTimeline">{{cite web |url=https://www.washingtonpost.com/graphics/2018/national/timeline-parkland-shooter-nikolas-cruz/ |title=Red flags: The troubled path of accused Parkland shooter Nikolas... |website=The Washington Post |access-date=2025-08-11}}</ref> An analysis of his life reveals a trajectory marked by early developmental challenges, significant personal trauma, and a pattern of behavior that provided numerous, yet ultimately unheeded, warnings.<ref name="WaPoTimeline" />

== Personal history and developmental challenges ==
Nikolas Cruz's biological mother had a documented history of severe substance abuse, including heavy drinking and the use of crack cocaine during her pregnancy, forming the basis of his legal defense's argument that his brain was likely damaged ''in utero'' by Fetal Alcohol Spectrum Disorders (FASD).<ref name="MarshallProject">{{cite web |url=https://www.themarshallproject.org/2024/09/17/school-shooting-death-penalty-parkland-nikolas-cruz |title=How Sparing the Parkland Shooter's Life Changed Florida's Death... |website=The Marshall Project |access-date=2025-08-11}}</ref> Adopted as an infant, he was formally diagnosed as "developmentally delayed" by age three and exhibited extreme behaviors in preschool, including hitting and biting other children.<ref name="APChaos">{{cite web |url=https://apnews.com/article/crime-shootings-florida-fort-lauderdale-parkland-school-shooting-2cc9e1f433788bb16445249055715b1e |title=Testimony: School shooter's home ruled by chaos |website=AP News |access-date=2025-08-11}}</ref>

His developmental struggles were compounded by acute trauma at age five, when he witnessed his adoptive father die of a heart attack.<ref name="APChaos" /> This left his adoptive mother, Lynda Cruz, to raise two exceptionally challenging sons on her own.<ref name="APChaos" /> On November 1, 2017, just over three months before the shooting, Lynda died, leaving Nikolas, then 19, fully orphaned and in a state of acute crisis and instability.<ref name="WaPoTimeline" />

== Mental and behavioral health profile ==
Cruz was deeply entrenched in the mental health system from a young age, receiving hundreds of hours of therapy.<ref name="APChaos" /> Over the years, he was assigned a variety of diagnoses, including Attention Deficit Hyperactivity Disorder (ADHD), Oppositional Defiant Disorder (ODD), and depression.<ref name="PsychiatricTimes">{{cite web | url = https://www.psychiatrictimes.com/view/the-parkland-school-mass-shooting-and-its-psychiatric-implications | title = The Parkland School Mass Shooting and Its Psychiatric Implications | website = Psychiatric Times | access-date = 2025-08-11 }}</ref> A 2016 investigation by the Florida Department of Children and Families (DCF) also noted he had autism, though this was later disputed.<ref name="WaPoTimeline" /> His defense team's primary argument centered on the theory that his actions were the result of congenital brain damage from FASD.<ref name="MarshallProject" /> The prosecution countered that his actions were premeditated and indicative of an antisocial personality disorder, arguing that he was malingering or faking many of his psychiatric symptoms.<ref name="CBSswastikas">{{cite web |url=https://www.cbsnews.com/miami/news/parkland-gunman-nikolas-cruzs-swastikas-court-fight/ |title=Parkland gunman Nikolas Cruz's use of swastikas is focus of court... |website=CBS News |access-date=2025-08-11}}</ref><ref name="YouTubeFaked">{{cite web |url=https://www.youtube.com/watch?v=xHLcpZ-B_Bc |title=Parkland shooter Nikolas Cruz "faked" psychiatric symptoms after shooting, expert says |website=YouTube |access-date=2025-08-11}}</ref>

He displayed a deep obsession with guns and violence, researching past school shootings and expressing racist, antisemitic, and homophobic views online.<ref name="WikipediaCruz">{{cite web |url=https://en.wikipedia.org/wiki/Nikolas_Cruz |title=Nikolas Cruz - Wikipedia |website=Wikipedia |access-date=2025-08-11}}</ref><ref name="PsychiatricTimes" /> In September 2017, he posted a comment on a YouTube video under his own name that read, "Im going to be a professional school shooter," a public declaration of intent that was reported to the FBI but not sufficiently investigated.<ref name="MarshallProject" />

== An exhaustive history of animal cruelty ==
A defining and deeply disturbing aspect of Cruz's behavioral history was his prolonged and escalating pattern of cruelty toward animals.<ref name="FDLEbehavior">{{cite web | url = http://www.fdle.state.fl.us/MSDHS/Meetings/November-Meeting-Documents/Nov-13-145pm-Cruz-Behavior-Chris-Lyons.aspx | title = Unreported Information Showing Nikolas Cruz's Troubling Behavior | website = Florida Department of Law Enforcement (FDLE) | access-date = 2025-08-11 }}</ref> This behavior, which began in his childhood and continued into his teenage years, was not an isolated phase but a consistent feature of his pathology.<ref name="FDLEbehavior" /> The acts of cruelty were varied, public, and reportedly a source of pride for him.<ref name="FDLEbehavior" /> This history provides a critical window into his developing lack of empathy, his desensitization to violence, and his use of cruelty as a means of asserting power and constructing a fearsome identity.<ref name="FDLEbehavior" /> His cruelty was often "up close and personal," involving direct physical contact, which research suggests is a more severe indicator of future violence.<ref name="WBIRepository">{{cite web | url = https://www.wellbeingintlstudiesrepository.org/cgi/viewcontent.cgi?article=1097&context=aniubpos | title = Animal Cruelty Does Not Predict Who Will Be A School Shooter | website = WBI Studies Repository | access-date = 2025-08-11 }}</ref> He also frequently bragged to peers about his actions and posted pictures and videos of dead and mutilated animals on platforms like Instagram and Snapchat, using the cruelty as a form of perverse social currency to construct a fearsome identity.<ref name="FDLEbehavior" /><ref name="CBSswastikas" />

== Systemic failures ==
The tragedy was the culmination of a catastrophic series of systemic failures, where numerous opportunities for intervention were missed by schools, law enforcement, and social service agencies.<ref name="SunSentinelPath">{{cite web |url=https://projects.sun-sentinel.com/cruz-troubled-life/ |title=Nikolas Cruz: The violent path of a teenage killer |website=South Florida Sun Sentinel |access-date=2025-08-11}}</ref> A pivotal failure occurred in 2016 when he was transferred from a specialized school for students with emotional and behavioral disorders to the mainstream environment of Marjory Stoneman Douglas High School with significantly less support.<ref name="EdWeekReport">{{cite web |url=https://www.edweek.org/teaching-learning/parkland-shooting-report-sharpens-focus-on-special-education-and-due-process/2018/08 |title=Parkland Shooting Report Sharpens Focus on Special Education and Due Process |website=Education Week |access-date=2025-08-11}}</ref> As an adult, he withdrew from all special education services, a decision his disabilities likely impaired him from making rationally, and was eventually expelled.<ref name="EdWeekReport" />

The Broward Sheriff's Office had extensive contact with Cruz for years, responding to at least two dozen calls at his home, but never arrested him.<ref name="SunSentinelPath" /> The FBI received two separate, explicit tips about his homicidal intentions—including his YouTube comment and a detailed call from a close family friend in January 2018 warning of his gun ownership, desire to kill, and history of "mutilating small animals"—both of which were mishandled and not investigated.<ref name="MarshallProject" /><ref name="FBISummary" />

== The attack and legal proceedings ==
On February 14, 2018, Cruz arrived at the campus of his former high school armed with a legally purchased AR-15-style rifle. In a rampage that lasted approximately six minutes, he killed 17 people (14 students and 3 staff members) and injured 17 others.<ref name="WikipediaParkland" /> He was arrested about an hour later.<ref name="WikipediaParkland" />

On October 20, 2021, Cruz pleaded guilty to all 34 counts against him.<ref name="WikipediaCruz" /> Although the prosecution sought the death penalty, the jury did not reach the unanimous decision required. Consequently, on November 2, 2022, Nikolas Cruz was sentenced to 34 consecutive life sentences without the possibility of parole.<ref name="MarshallProject" />
