Nikolas Cruz reached for his cellphone before his rifle.
Sometime before killing 17 people at Marjory Stoneman Douglas High School on Feb. 14, Cruz recorded three cellphone videos discussing his plan to murder students and staff.
"With the power of my AR-15 you will all know who I am," Cruz said in one video.
Prosecutors released the videos Wednesday afternoon as they prepare for a possible death penalty trial. The videos may offer insight into what motivated Cruz to commit Florida's worst school shooting, which has led to a nationwide debate over gun control.

Cruz, a former Stoneman Douglas student who seems to have meticulously planned his attack, expressed anger at his old classmates, saying they thought he was an "idiot and a dumb ass" when in fact it was they who had been "brainwashed by these f***ing political government programs." And he declared his love for a girl he identified only by her first name, saying he hoped to see her "in the afterlife."
The videos, all shorter than 90 seconds, will almost certainly bolster the prosecution's efforts to convict Cruz, 19, of first-degree murder, a capital offense: Under Florida law, such charges must be premeditated.
Fred Guttenberg, whose daughter Jaime was killed at Stoneman Douglas, said he was worried that media coverage of the videos, which he called "delusional," might inspire other school shootings. Guttenberg said he had read transcripts of the videos but would not watch them.
"I don’t want other kids to see what he said and think they’ll do it better," he told the Miami Herald Wednesday. "What he did has resulted in him being in jail where he will rot and die. He was caught and he is going to be abused in prison until he dies."
One of the videos shows Cruz wearing a green t-shirt and dark baseball cap and looking into the camera. In a matter-of-fact tone, Cruz discusses unleashing horrific violence.
"Hello. My name is Nik and I'm going to be the next school shooter of 2018," Cruz says calmly. "My goal is at least 20 people with an AR-15. ... Location is Stoneman Douglas in Parkland, Florida."
"It's going to be a big event," he added. "And when you see me on the news, you'll know who I am."
Then Cruz laughed.
"You're all going to die," he continues, making gunshot sounds. "Can't wait."
Cruz's massacre killed 14 students and three educators and left another 17 people wounded. He faces 17 counts of first-degree murder and 17 counts of attempted first-degree murder.
The recordings were released Wednesday by the Broward State Attorney's Office in response to a media request for discovery, which is when the state turns over all the potential evidence against a defendant. In Florida, many elements of discovery are considered a public record once they are made available to defense attorneys.
Authorities did not say when exactly the videos were made, although Cruz suggests in one that he would carry out the attack later the same day. His cellphone was confiscated as evidence after the attack.
Gordon Weekes, Cruz's lawyer from the Broward Public Defender's Office, declined to comment Wednesday.
The question of guilt has never been at issue: His lawyers have admitted Cruz was the shooter and insist he had a troubled life and should be spared execution. If the case goes to trial, the videos would certainly show Cruz was not insane and knew right from wrong, said Penny Brill, the former head of the legal bureau at the Miami-Dade State Attorney's Office.
"It shows premeditation," Brill said. "It wasn't a spur of the moment decision to shoot."
Experts who study the minds of mass shooters say they often make such videos.
"There is a certain group of school shooters who engaged in fame-seeking behavior. They want to be known," said Peter Langman, a clinical psychologist who authored the book "Why Kids Kill: Inside the Minds of School Shooters." "They want to change from a nobody into a somebody and the only way they can think to do that is to kill a lot of people."
Langman said it is also not unusual for school shooters to cast themselves as victims.
Cruz's violent and bizarre behavior worried neighbors and classmates for years before the Parkland massacre. He was legally able to purchase the AR-15 rifle he used in the assault. Some parents of the dead have argued that the Broward Sheriff's Office and Broward County Public Schools could have done more to stop the shooting, which took place in Stoneman Douglas' freshman building.
The videos show Cruz laid out his attack in advance. “Here’s the plan. I’m going to take an Uber in the afternoon before 2:40 p.m.,” he said in one video clip, the camera facing the ground, Cruz apparently sitting on a bench with a bicycle nearby.
“From there, I’ll go into the school campus, walk up the stairs, load my bags and get my AR and shoot people down at ... the main courtyard and people will die.”
Cruz opened fire at 2:21 p.m. on Valentine's Day in the freshman building. He arrived on campus in an Uber. Had it not been for the impact glass on the freshman building's third floor, Cruz would have been able to shoot down on crowds of fleeing students, raising the potential death toll considerably.
Police say Cruz confessed to the crime after being arrested more than an hour after the attack. He was able to elude BSO deputies and police officers who responded to the scene, ditching his weapon inside a stairwell before slipping off campus and walking to a nearby Walmart and McDonald's.
In another clip, Cruz appeared to read pre-written words.
“Today is the day, the day it all begins. The day of my massacre shall begin,” Cruz said. “All the kids in the school will run in fear and hide. From the wrath of my power they will know who I am.”
In the clip, Cruz casts himself as a victim, saying he lives in “seclusion and solitude” and that his life was "nothing and meaningless."
He also seems to profess his devotion to a girl — and suggests he didn’t intend to survive.
“My love for you...will never go away,” Cruz says. “I hope to see you in the afterlife.”
