Nikolas Cruz jumped out of the Uber car and walked toward building 12 of the Marjory Stoneman Douglas High School, carrying a black duffel bag and a black backpack. A man inside the school spotted Cruz, and knew he was a former student. A troubled kid. The man radioed a co-worker, and within a minute heard gunshots.

The 19-year-old was wearing a maroon shirt, black pants and a black hat. The man, whose name was blacked out from a sheriff's affidavit, told detectives Cruz was moving "purposefully."

He slipped into the building, entered a stairwell and extracted a rifle from his bag, authorities said. He shot into four rooms on the first floor - going back to spray bullets into two of the rooms a second time - then went upstairs and shot a single victim on the second floor. He ran to the third floor, where according to a timeline released by the Broward County Sheriff's Office, three minutes passed before he dropped the rifle and backpack, ran back down the stairs and quickly blended in with panicked, fleeing students.

From the time Cruz entered the building until the time he left, only six minutes passed. During that brief time, he shot more than two dozen students, 17 of them fatally.

After the rampage, the suspect headed to a Wal-Mart and bought a drink at a Subway restaurant before walking to a McDonald's.

About 40 minutes later after leaving the McDonald's, a deputy saw him walking down a suburban South Florida street and grabbed him. He didn't put up a fight.

The details of Wednesday's carnage at the Parkland, Florida, high school emerged a day later from witnesses and law enforcement reports.

Cruz was ordered held without bond at a brief court hearing. He wore an orange jumpsuit with his hands cuffed at his waist. His attorney did not contest the order and had her arm around Cruz during the short appearance.

New research on active shooter attacks shows the chances of being wounded are nearly double when semi-automatic rifles are involved, compared with non-automatic weapons.

But once hit, the chances of dying remain about the same regardless of the weapon.  

STORYLINE:

Semi-automatic rifles were used at shootings at Parkland High School, Sandy Hook Elementary School and Orlando's Pulse night club.

Now new research has been released showing the catastrophic effect of this type of shooting.

The research - led by the Brigham and Women's Hospital in Boston examined FBI data on the nearly 250 active shooter incidents in the United States since 2000. Almost 900 people were wounded and 718 were killed.

One in four of these attacks involved semi-automatic rifles. These weapons automatically load each bullet after firing although firing requires pulling the trigger for each round.

The guns, which include some assault rifles, are often thought of as being more lethal, and since they can fire rapidly, the chances of being hit in those circumstances are high, the results show.

But in active shooter attacks, which tend to occur in confined spaces and with an intent to kill, the results suggest all types of guns can be equally deadly.

Dr. Adil Haider is a public health researcher and trauma surgeon at Brigham and Women's Hospital in Boston and the lead author of the research.

"What was very interesting is that if you got hurt or shot by a handgun, or the semiautomatic weapon, for the person who got shot the chance of death is about the same," he says.

Overall, 44 percent of people that were hit in active shooter attacks involving semi-automatic weapons died, the same percentage as those wounded in non-automatic weapon attacks.

The average number of people wounded in semi-automatic attacks totaled nearly six, versus about three in attacks with a non-automatic weapon. Roughly four people were killed on average in semi-automatic attacks, compared with about two in other attacks, the study found.

"Conventional wisdom is that if you get hurt by a semiautomatic weapon (they have) much higher velocity, they can shoot much farther, typically, there's going to be a higher likelihood of death. But perhaps because this was just looking at active shooter incidents, where somebody is really bent on hurting and killing people, and usually in a confined space, maybe that's why those handguns were very lethal as well," says Haider.

According to  Haider the study highlights a need to better track details on types of weapons used in active shooter attacks.  FBI data does not detail whether weapons used were semi-automatic so the researchers got that information from court and police documents and news media reports.

Haider notes that his research team included a combat veteran and several other gun owners who believe in the right to bear arms.

Dr. Cassandra Crifasi, deputy director of the Johns Hopkins Center for Gun Policy and Research, didn't participate in the research but she highlights some of its key findings.

"I think this study confirms what many have thought, which is the use of semiautomatic rifles in these types of events allow for significantly more injury and death because of some of the features of these types of rifles that allow shooters to fire many rounds without having to reload."

A longtime gun owner and sports shooting enthusiast, Crifasi says her understanding of gun culture brings a different perspective to gun research and safety.

"I think that the main thing is that there are gun owners like me, not just researchers but gun owners who support common sense solutions to reducing gun violence, including a discussion about large capacity magazines, for example."

The results of the analysis were published Tuesday (11th September 2018) in the Journal of the American Medical Association.

Parents waited outside Marjory Stoneman Douglas High School in Parkland, Florida as their kids finished their second day of school since 17 of their peers and teachers were shot and killed.

Melissa Broccoli and Christine Dunhill were shaking as they reunited Thursday at their usual pick-up spot outside the school. They had not seen each other since Feb. 14, when they believe Nikolas Cruz drove past them in an Uber onto campus, where he fatally shot 17 people.

"You re-live everything when you come back here and you have to park in the same spots," Broccoli said.

The women said they had felt helpless during the shooting, and they were trying to be strong for their children.

"I think they are more courageous and strong than the parents are. I mean, they walked back into that building," Broccoli said.

(DUNHILL) "And he had to drive past us, he had to drive past us because he took the Uber and he went right in the way that we sit, right?.."

(BROCCOLI) "Yes, well that's why they told us to get back in the car, yes, but we didn't know at the time that the Sheriff was yelling at us because we were so close to the school and they felt he was coming down this way to go past the underpass that day. But, you know, again, coming back here is difficult but it's a necessity and we will deal with it just the way our kids are dealing with it, in a very strong and courageous way."

(DUNHILL) "Well, we have to for them.."

(BROCCOLI) "Well I think, I gotta be honest with you, I think they are more courageous and strong than the parents are. I mean, they walked back into that building. We were on the outside and of course as a parent, pure terror, an extreme feeling of helplessness that you could never imagine in your whole entire life, standing out here, hearing gun shots, smelling the smoke. It's, it's absolutely terrifying and you feel so helpless because what are you going to do? You can't run into the school, you can't help your child, you tell your child don't worry I'm always here, Mommy is here, we will take of you I mean while we are standing in front of the school not being able to do anything,so.."

(DUNHILL)  "And the fact that this morning I wake up and I'm up and I think my poor child is going through this."

A junior at the Florida high school where 17 people were killed says she's 'traumatized and heartbroken' this happened.

Olivia Prochilo said her first reaction when she heard there was a shooting was 'of course this would never happen to our school."

But Prochilo said it didn't take long to realize that the shooting at Marjory Stoneman Douglas High School in Parkland was all too real.

"We saw kids running at us, saying to run, and run, that shots have been fired and like immediately you just go into panic mode and you don't know what to think," said Prochilo.

"I think I'm still in a little bit of shock, if I had to experience being in the freshmen building hearing shots and walking over dead bodies, as some of the students had to get out of the building. I don't think I would have been able to be here today."

Nineteen-year-old Nikolas Cruz has been charged with 17 counts of premeditated murder in the Wednesday afternoon shooting in Parkland, Florida.

The Federal Bureau of Investigation (FBI) admitted on Friday that it received a tip off in early January about Nikolas Cruz, the suspected Florida school shooter who killed 17 people on Wednesday, but failed to act.

The FBI said in a statement that a person close to the shooter called the agency's tip line on Jan 5 to warn about "Cruz's gun ownership, desire to kill people, erratic behavior, and disturbing social media posts, as well as the potential of him conducting a school shooting."

On top of that, police had been called 39 times to the shooter's home, with the reported call outs ranging from domestic disturbance to elder and child abuse.

The statement came two days after the 19-year-old Cruz opened fire with an AR-15 rifle at students and teachers at the Marjory Stoneman Douglas High School in the city of Parkland in Broward County, just north of Miami on the state's southeastern tip.

In addition to the 17 killings, the shooting also injured 14 others.

The FBI said that protocols were not followed for the January tip, which therefore meant the information was not provided to the Miami office, and no further investigation was conducted at that time.

Cameron Kasky, a senior at the Marjory Stoneman Douglas High School who survived the shooting, spoke about the sense of anger following the tragic killings.

"We are all angry. We are not confused any more, we know what's going on. We know that politicians like Rick Scott and Marco Rubio are creating a facade that this is normal, this is inevitable, there's nothing we could do to stop this. And people are realizing that we've been fooled," said Kasky.

Wednesday's massacre raised concerns about potential failure in school security and sparked ongoing debates about the U.S. gun control laws.

Cruz, who was previously expelled from the school for disciplinary reasons, made a brief court appearance on Thursday and was ordered held without bond.

STORYLINE:

Nikolas Cruz jumped out of the Uber car and walked toward building 12 of the Marjory Stoneman Douglas High School, carrying a black duffel bag and a black backpack. A man inside the school spotted Cruz, and knew he was a former student. A troubled kid. The man radioed a co-worker, and within a minute heard gunshots.

The 19-year-old was wearing a maroon shirt, black pants and a black hat. The man, whose name was blacked out from a sheriff's affidavit, told detectives Cruz was moving "purposefully."

He slipped into the building, entered a stairwell and extracted a rifle from his bag, authorities said. He shot into four rooms on the first floor - going back to spray bullets into two of the rooms a second time - then went upstairs and shot a single victim on the second floor. He ran to the third floor, where according to a timeline released by the Broward County Sheriff's Office, three minutes passed before he dropped the rifle and backpack, ran back down the stairs and quickly blended in with panicked, fleeing students.

From the time Cruz entered the building until the time he left, only six minutes passed. During that brief time, he shot more than two dozen students, 17 of them fatally.

After the rampage, the suspect headed to a Wal-Mart and bought a drink at a Subway restaurant before walking to a McDonald's.

About 40 minutes later after leaving the McDonald's, a deputy saw him walking down a suburban South Florida street and grabbed him. He didn't put up a fight.

The details of Wednesday's carnage at the Parkland, Florida, high school emerged a day later from witnesses and law enforcement reports.

Cruz was ordered held without bond at a brief court hearing. He wore an orange jumpsuit with his hands cuffed at his waist. His attorney did not contest the order and had her arm around Cruz during the short appearance.

At least 17 people were killed and 14 others were wounded after a 19-year-old gunman opened fire Wednesday at a high school in the U.S. state of Florida, according to authorities.

The shooting took place when students were being dismissed at Marjory Stoneman Douglas High School in the city of Parkland, just north of Miami.

The suspected gunman, captured shortly after the shooting, was identified as Nikolas Cruz, a 19-year-old former student who had been expelled from the school. An AR-15 semi-automatic rifle was found at the site.

Broward County Sheriff Scott Israel told reporters that of the casualties, 12 happened within the school, two outside and one at a nearby road. Two more also succumbed of their injuries at the hospital, leading to a current total of 17 fatalities.

All of the victims have been identified, Israel said, but their identities will not be made public until their families have been notified.

In addition to the 17 who lost their lives, at least 14 others were wounded, five of whom are battling life-threatening injuries, according to hospital authorities.

This shooting is among the 10 deadliest mass shootings in modern U.S. history.

U.S. President Donald Trump said that he was making plans to visit the scene of the attack, meet with the families of the victims and give a televised national address regarding the mass shooting on Thursday.

The incident took place after Parkland, with a population of 31,000 in 2016, was recently listed by a national survey as one of the safest cities in Florida.

The mass school shooting has again sparked debate over gun control in the U.S.

According to the latest Gallup poll, 60 percent of U.S. respondents support stricter gun laws, while only five percent want less strict ones.

"I think the gun law is ridiculous to be honest with you. No one should have guns, except law enforcement, in my opinion," said a Florida resident.

STORYLINE:

Six best friends from Marjory Stoneman Douglas High School recounted to The Associated Press the moments of terror they witnessed during a mass shooting Wednesday afternoon in their school that killed 17 people.

17-year-old Jonathan Blank was in a classroom that was targeted by 19-year-old Nikolas Cruz.

"The door has a window on it and like a glass little window, and he just shot right through it and just shot from outside," Blank said.

"He never came into the room. But he started spraying inside of the room, and he just hit people."

"You could hear the shots," student John Greenberg said. "I heard, must have been like seven I'd say that's when it just started like, that's when chaos erupted. "

Cruz was charged with murder Thursday in the deaths of 17 people who were fatally shot at a huge Florida high school in the nation's deadliest school attack in five years.

Authorities offered no details about a possible motive, except to say that Cruz had been kicked out of the high school, which has about 3,000 students.

"I don't even know how to put it into words but he was always the odd man out. If you were to put 100 kids in front of me and had to pick one that would possibly do something this horrible it would be him, sadly," said 16-year-old

Noah Kaufman.

Students who knew him described a volatile teenager whose strange behavior had caused others to end friendships with him.

STORYLINE:

Hundreds of thousands across Florida observed a moment of silence on Thursday to mark the one-year anniversary of the deadly shooting at Marjory Stoneman Douglas High School in Parkland that killed 17 people.

The massacre renewed the national debate on guns and school safety and turned some victims' parents and surviving students into political activists.

But Thursday's anniversary was primarily about remembering the 14 students and three staff members who died in the third high-profile mass shooting in Florida since 2016.

The moment of silence was observed at 1017 local time (1517GMT).

The shooting actually began around 1420 local time, but school officials picked a different time because Stoneman Douglas students were being dismissed early to avoid being on campus at the time of the shooting.

The decision to hold it at 1017 local time was made in honour of the 17 slain.

Students of a Florida high school which was the scene of a shooting spoke of their horror after Wednesday's attack, while they were being reunited with their parents at a South Florida hotel.

Officers transported the students from Marjory Stoneman Douglas High School in Parkland to a Marriott Hotel in Coral Springs.

Broward County Sheriff Scott Israel said the attack began outside the school Wednesday afternoon.

He told reporters that authorities subsequently found 12 people dead in the building and two more dead just outside the school and one more in a nearby street.

Two other people died later under medical treatment.

"I heard gunshots. I thought it was firecrackers. But after I heard the last shot I was like oh, no," said student Manuel Barraza.

The suspect, a 19-year-old former student of Marjory Stoneman Douglas High School, was in custody.

The gunman was identified as Nikolas Cruz by a US official briefed on the investigation.

The official spoke on condition of anonymity because he was not authorised to discuss the information publicly.

++ENDS ON SOUNDBITE++

Students at the Marjory Stoneman Douglas High School in Florida returned for their first day of classes on Wednesday amid a heavy police presence, two weeks after a former student opened fire and killed 17 people on campus.

The deadly shooting, one of worst school massacres in U.S. history, shocked the nation on the afternoon of Feb. 14, sparking wide debates about gun control and security in schools.

Many of the students returning to the school on Wednesday said they still felt nervous and unsafe.

"I'm really nervous to go back, I don't really want to go back at all. I don't feel safe at school anymore. I don't at all, just the way he kind of went in, just on his own without any kind of security. So many lives are lost, it doesn't make it any easier," said Elizabeth Rangel, a student.

She was among those calling for major reforms to be made not only in gun control, but also in other aspects.

"Gun control reforms, any kind of reforms, mental health reforms, to background checks on gun control, everything," said Rangel.

Students are still mourning the loss of their friends and classmates, but some hope that getting back to a regular routine will help them come to terms with the tragedy.

"I think it's going to be good for everyone to try and get started back into a normal routine. Because that's how it should be, but it's going to be hard," said student Hunter Polyak.

A stream of well-wishers were also gathered outside the school to offer the students support and ease their difficult return.

"You can see the pain on a lot of their faces. But when you hand a kid a flower, it immediately brings a smile. And some of them I would hand a flower and say, 'you've got to give me a smile for a flower,' and immediately they would break into a smile. So that's mission accomplished, that is just making their first day back to school just a little easier, that's what we wanted to do," said Rod Skirvin, vice president of the Broward County Police Benevolent Association.

Hundreds of off duty police officers from all over Florida and some from as far away as New York City also came to show their support. Additional grief counselors were on site and even therapy dogs were brought along to ease the pain.

Most of the students are suffering but said they won't let this tragedy define them.

"I mean we have to go back strong but obviously it's still a little bit fresh but we have to try keep going and move on," said Nicole Suarez, a student.

In response, Florida Governor Rick Scott introduced a 500 million dollar funding proposal designed to keep students safe, which includes placing a mandatory law enforcement officer in every school, more training for school personnel and an expansion of mental health services for students across the state.

Protesters are set to continue their national fight for gun control with a mass protest planned next month in Washington.

He said students knew, "he was one of those kids you didn't mess with," and did not associate with.

Hundreds of people turned out at an anti-gun rally in Fort Lauderdale on Saturday.

Survivors of the shooting at Marjory Stoneman Douglas High School spoke at the rally to condemn gun laws and rail against the National Rifle Association.

Delaney Tarr, who said she lost four of her close friends, expressed anger at how existing gun laws allowed for suspect Nikolas Cruz to legally buy the AR-15 semi-automatic rifle authorities say he fired Wednesday inside the school, killing 17 people.

Florida's child welfare agency investigated Cruz after he cut himself in an online video but found him stable, according to state records.

Cruz had been diagnosed with autism, a neurological disorder that often leads to social awkwardness and isolation, and attention deficit-hyperactivity disorder, or ADHD.

Cameron Kasky and David Hogg, who also survived the shooting, said thoughts and prayers are not enough anymore and urged people to get out and vote to help change existing gun laws.

"Our childhood is gone because that man, that man despite being diagnosed with autism, ADHD, despite being evaluated and not even committed by a mental health facility, despite being tipped off to the FBI multiple times was able to legally purchase an AR15. He was able to legally purchase that semi-automatic rifle and come into my school and slaughter 17 of my people. Because of these gun laws, people that I know, people that I love have died and I will never be able to see them again."

4. SOUNDBITE (English) Cameron Kasky, Student at Marjory Stoneman Douglas High School:

10. SOUNDBITE (English) David Hogg, Student at Marjory Stoneman Douglas High School:

"This fight is not going to be easy, this fight is not going to be short. We're going to have to continue four days, months, years and decades because the people in the special interests that want to pass these gun laws to make it easier for these people to get guns are not going to stop and we can't either. We need to get out and vote."
