PARKLAND, Fla. -- An orphaned 19-year-old with a troubled past and an AR-15 rifle was charged with 17 counts of premeditated murder Thursday morning after being questioned for hours by state and federal authorities following the. Fifteen wounded survivors were hospitalized as bodies were recovered from inside and around . Officials said the suspect shot into five classrooms and hid among students as they were fleeing the campus fearing for their lives.
was booked into the Broward County Jail early Thursday, still wearing the hospital gown he was given after being treated for labored breathing following his arrest. Later in the day, a Broward County Sheriff's Office report said Cruz confessed to being the shooter at Marjory Stoneman Douglas High School. He told interrogating officers that he "began shooting students that he saw in the hallways and on school grounds" on Wednesday afternoon, according to the report.
The report added that Cruz told officers he "brought additional loaded magazines to the school campus and kept them hidden in a backpack until he got on campus to begin his assault." Cruz told investigators that as students began to flee, he decided to discard his AR-15 rifle and a vest he was wearing so he could blend in with the crowd. Police recovered the rifle and the vest.
The police report added that Cruz purchased the rifle in February 2017.
Cruz appeared in court Thursday afternoon and was ordered held without bond. He was wearing an orange jumpsuit with his hands cuffed at his waist during the hearing.
Public defender Melisa McNeill said Cruz is fully aware of what's going on but he's also just a "broken human being." She said her client is sad and remorseful, and became emotional while speaking to reporters, saying she's fully aware of the impact the shooting has had on the community. She had her arm around Cruz during the brief hearing.
Timeline as it happened Wednesday, Feb. 14
Broward County Sheriff Scott Israel said the suspect arrived at the high school at 2:19 p.m. Wednesday, entering the east stairwell with a rifle inside a black, soft case. The suspect exited the stairwell and pulled the rifle out of the case at 2:21 p.m. local time. He then readied his rifle and began shooting into rooms 1215, 1216, 1214 ... he then went back into 1216, 1215 and 1214. The suspect then took the west stairwell to the second floor and shot one victim in room 1234 on the second floor. The suspect then took the east stairwell to the third floor ... he then dropped his rifle and backpack containing extra ammunition and ran down the stairs ... exiting building 12 and ran toward the tennis courts. The suspect then turned west and tried to mix in with students who were trying to run away fearing for their lives. The suspect then arrived at a Walmart store and bought a drink at the Subway and left the Walmart on foot.
The suspect then arrived at a McDonald's around 3:01 p.m. and he left on foot. At 3:41 p.m., 40 minutes after leaving McDonald's, the suspect was detained at 4700 Wyndham Lakes Drive by the Coconut Creek Police Department.
Israel said law enforcement officials (between the FBI, the Broward County Sheriff's Office and other agencies) interviewed more than 2,000 individuals. This is very fluid situation, Israel mentioned, and that it's going to take time to sift through the information.
Israel mentioned they have no plans to release any surveillance video as the investigation is underway.
Details on suspect's weapon
ATF special agent in charge Peter Forcelli said the suspect's firearm was purchased legally in the state of Florida just short of a year ago by the suspect. He urged thoughts and prayers for the families, victims and first responders affected by this incident.
Sheriff Israel said the suspect bought the weapon in Coral Springs, Florida, at a dealership called Sunrise Tactical.
Cruz was also equipped with a gas mask, smoke grenades and multiple magazines of ammunition. He killed 17 people, injuring 15 and sending hundreds of students fleeing into the streets.
Deadliest school shooting since 2012
Just before gunfire broke out Wednesday, some students at the school thought they were having another fire drill. Such an exercise had forced them to leave their classrooms hours earlier. So when the alarm went off Wednesday afternoon shortly before they were to be dismissed, they once again filed out into the hallways.
That's when police say Cruz, equipped with a gas mask, smoke grenades and multiple magazines of ammunition, opened fire with a semi-automatic weapon, killing 17 people, injuring 15 and sending hundreds of students fleeing into the streets.
It was the nation's deadliest school shooting since a gunman attacked an elementary school in Newtown, Connecticut, more than five years ago. The overall death toll differs by how such shootings are defined, but Everytown For Gun Safety has tallied 290 school shootings in America since 2013, and this attack makes 18 so far this year.
The FBI said Thursday it is investigating whether or not a disturbing YouTube comment reported to them last year was posted by the suspect in Wednesday's shooting. Robert Lasky, special agent in charge of the FBI Miami Division, said at a press conference the FBI received information aboutthat said, "I'm going to be a professional school shooter."
"No other information was included with that comment, which would indicate a time, location or the true identity of the person who made the comment," Lasky said. "The FBI conducted database reviews, checks, but was unable to further identify the person who actually made the comment."
Lasky said that YouTube removed the comment after receiving a complaint. FBI Jackson interviewed the person who made the complaint -- the person resides in Mississippi and has no connection or knowledge about the the person who posted the comment.
Jeff Pegues reports that Ben Bennight warned the FBI last September about the comment and that he spoke with the FBI last year for about 20 minutes, and there was no follow-up from the FBI after that initial conversation.
Bennight told Pegues he spoke with the FBI Wednesday night again for about 20 minutes. They wanted to know if he knew anything more after first reporting the YouTube video last year.
In another incident, a law enforcement source said the Broward County Sheriff's Office was apparently notified in February 2016 of an Instagram posting under the name of Nikolas Cruz that he was going to shoot his school, CBS News senior investigative producer Pat Milton reports. The Instagram posting was accompanied by a photo of Cruz holding a weapon. It had been posted a month earlier, in January 2016.
"Is this who I need to stop?"
A law enforcement source said the suspect in Wednesday's shooting appears to have pulled the school fire alarm, causing chaos, then started shooting, Milton reported.
Cruz escaped the school undetected following the shooting by blending in with students rushing to evacuate, a law enforcement source told CBS News. He was arrested in a nearby residential neighborhood.
Coconut Creek police officer Michael Leonard, who arrested Cruz, said Thursday that Cruz looked like a "" when he spotted him walking away from the school. Leonard said his department was responding to the shooting when he saw someone matching the description of the suspect.
"For a quick moment I thought, 'Could this be the person, is this who I need to stop? Training kicked in. I pulled my vehicle over immediately. I engaged the suspect. He complied with my commands," Leonard said. "He was taken into custody without any issues."
Student Jamie Guttenberg and assistant football coach and security guard Aaron Feis were killed in the shooting, reports CBS News correspondent Manuel Bojorquez. Broward County Sheriff Scott Israel confirmed Wednesday night that a football coach was killed and the son of a sheriff's deputy was shot and is in stable condition.
Israel said the bodies of 12 of the 17 victims were found inside the building. He said two other bodies were discovered outside the school, another was found a short distance away along a local road and two others died at a hospital.
Authorities offered no immediate details about Cruz or his possible motive. They said he'd been kicked out of the high school, which has about 3,000 students. Students who knew him described a volatile teenager whose strange behavior had caused others to end friendships with him.
The leader of a white nationalist militia said Cruz was a member of his group and participated in paramilitary drills in Tallahassee. Jordan Jereb told The Associated Press on Thursday that his group, the Republic of Florida, wants Florida to become its own white ethno-state. He said his group holds "spontaneous random demonstrations" and tries not to participate in the modern world.
Jereb said he didn't know Cruz personally and that "he acted on his own behalf of what he just did and he's solely responsible for what he just did." He also said he had "trouble with a girl" and he believed the timing of the attack, carried out on Valentine's Day, wasn't a coincidence.
Uber confirmed Thursday that Cruz used the ridesharing service before the shooting. The company said it is assisting law enforcement with the investigation. It wouldn't answer questions about whether the Uber driver noticed anything concerning about the suspect's behavior or if he was carrying a gun or a large case.
Israel said during a Thursday late afternoon press conference that the driver is not complicit or affiliated with the suspect in any way.
"One heavy heart"
President Trump, saying it turned the school into "the scene of terrible violence, hatred and evil." He said he is making plans to visit Parkland and that later this month, he will be meeting with the nation's governors and attorney generals, "where making our schools and our children safer will be our top priority."
He said his administration is "committed to working with state and local leaders to help secure our schools and tackle the difficult issue of mental health."
"It is not enough to simply take actions that make us feel like we are making a difference," he said. "We must actually make that difference."
"Our entire nation with one heavy heart is praying for the victims and their families," he said.
Earlier, Mr. Trump tweeted about the shooting. "So many signs that the Florida shooter was mentally disturbed, even expelled from school for bad and erratic behavior," he tweeted.
He has cited mental health before as a cause for mass shootings, dismissing questions about gun control.
Speaking Thursday, Attorney General Jeff Sessions said, "We've got to confront the problem. There's no doubt about it."
"We've got to reverse these trends" that we are seeing in shootings, he said.
Florida Gov. Rick Scott said he will work to make sure people with mental illness do not get guns.
"We want to make sure this never happens again," he said.
"The violence has to stop," he said. "We cannot lose another child in this country to violence in a school."
Broward County Sheriff Scott Israel called for giving law enforcement more power to detain people who make threats.
"What I'm asking our lawmakers to do is go back to places like Tallahassee and Washington, D.C., to give police the power," the sheriff said, to detain people who make graphic threats or post disturbing material online, and bring them involuntarily to mental health professionals to be examined.
The sheriff also castigated people who he said are making copycat threats at other schools, warning that anyone caught will be fully prosecuted.
"Sadly there have been copycat threats made today in other schools. We will respond to every threat," he said Thursday, adding that authorities will respond in full to every threat and investigate.
Who is Nikolas Cruz?
Cruz's mother, Lynda Cruz, died of pneumonia on Nov. 1 neighbors, friends and family members said, according to the Sun Sentinel. Cruz and her husband, who died of a heart attack several years ago, adopted Nikolas and his biological brother, Zachary, after the couple moved from Long Island in New York to Broward County.
The boys were left in the care of a family friend after their mother died, family member Barbara Kumbatovich, of Long Island, said.
Unhappy there, Nikolasin northwest Broward. The family agreed and Cruz moved in around Thanksgiving. According to the family's lawyer, who did not identify them, they knew that Cruz owned the AR-15 but made him keep it locked up in a cabinet. He did have the key, however.
The Dollar Tree retail chain confirmed Thursday that Cruz worked at their store in Parkland. In a Thursday statement, the Dollar Tree said they'll share any information about him with local and federal officials that may help with the investigation. The retailer also expressed sympathy for the Parkland community and those affected by the attack.
Attorney Jim Lewis said the family is devastated and didn't see this coming. They are cooperating with authorities, he said.
Victoria Olvera, a 17-year-old junior at the school, said Cruz was expelled last school year because he got into a fight with his ex-girlfriend's new boyfriend. She said he had been abusive to his girlfriend.
"I think everyone had in their minds if anybody was going to do it, it was going to be him," she said.
Student Brandon Minoff told CBSN he had had classes with Cruz. Minoff described the suspect as a "strange kid."
Another student told CBS News about the suspect, "The kid was crazy. I had engineering with him a couple years ago and he wasn't allowed to come to school with a backpack and he would threaten students and break glass and get into fights so he got kicked out of school."
Broward County Sheriff Scott Israel said investigators were dissecting the suspect's social media posts.
"And some of the things that have come to mind are very, very disturbing," he added without elaborating.
Daniel Huerfano, a student who fled Wednesday's attack, said he recognized Cruz from an Instagram photo in which Cruz posed with a gun in front of his face.
Huerfano recalled Cruz as a shy student and remembered seeing him walking around with his lunch bag. "He was that weird kid that you see ... like a loner," he added.
Cruz was taken into custody without a fight about an hour after the shooting in a residential neighborhood about a mile away. He had multiple magazines of ammunition, authorities said.
"It's catastrophic. There really are no words," said Israel.
"I thought maybe I could die"
As of 9 p.m. ET Wednesday, Israel said, 12 of the 17 people who lost their lives had been identified. Israel said authorities wouldn't release the names of the victims until all the families are notified. He said some of the students didn't have their backpacks or identification on them.
Frantic parents rushed to the school to find SWAT team members and ambulances surrounding the huge campus and emergency workers who appeared to be treating the wounded on sidewalks. Students who hadn't run began leaving in a single-file line with their hands over their heads as officers urged them to evacuate quickly.
Hearing loud bangs as the shooter fired, many of the students inside hid under desks or in closets, and barricaded doors.
"We were in the corner, away from the windows," said freshman Max Charles, who said he heard five gunshots. "The teacher locked the door and turned off the light. I thought maybe I could die or something."
As he was leaving the building, he saw four dead students and one dead teacher. He said he was relieved when he finally found his mother.
"I was happy that I was alive," Max said. "She was crying when she saw me."
Noah Parness, a 17-year-old junior, said he and the other students calmly went outside to their fire-drill areas when he suddenly heard popping sounds.
"We saw a bunch of teachers running down the stairway, and then everybody shifted and broke into a sprint," Parness said. "I hopped a fence."
Most of the fatalities were inside the building, though some victims were found fatally shot outside, the sheriff said.
The scene was reminiscent of the Newtown attack, which shocked even a country numbed by the regularity of school shootings. The Dec. 14, 2012, assault at Sandy Hook Elementary School killed 26 people: 20 first-graders and six staff members. The 20-year-old gunman, who also fatally shot his mother in her bed, then killed himself.
Not long after Wednesday's attack in Florida, Michael Nembhard was sitting in his garage on a cul-de-sac when he saw a young man in a burgundy shirt walking down the street. In an instant, a police cruiser pulled up, and officers jumped out with guns drawn.
"All I heard was 'Get on the ground! Get on the ground!'" Nembhard said. He said Cruz did as he was told.
The school was to be closed for the rest of the week.
"Our district is in a tremendous state of grief and sorrow," said Robert Runcie, superintendent of the school district in Parkland, about an hour's drive north of Miami. "It is a horrible day for us."
Runcie said there would be grief counseling for students and victims' families beginning early Thursday.
"We are going to pull through this as a community," Runcie said.
