During the last year, multiple schools across the U.S. have been impacted by shootings, which have resulted in the deaths of both students and faculty members.

Read on for a look at other school shootings that have taken place within the last year.

On March 20, a gunman, identified as 17-year-old Austin Rollins, shot 16-year-old sophomore Jaelynn Willey at Great Mills High School in Lexington Park, Maryland, authorities said. Willey died days later from her injuries.

Investigators believe the shooting was not random as the gunman and Willey had recently ended their relationship.

Rollins was fatally wounded during a confrontation with Deputy Blaine Gaskill, an armed school resource officer who doubles as a SWAT team member.

"Our school resource officer...pursued the shooter, engaged the shooter, fired a round at the shooter," St. Mary's County Sheriff Tim Cameron said. "The shooter fired a round as well. In the hours and days to come, we'll be able to determine if our school resource officer's round struck the shooter."

Gaskill was praised because he reportedly contained the situation in under a minute, Cameron said.

Willey's parents announced on March 22 that their daughter was brain dead and that they would be taking her off of life support. She died later that night.

Jaelynn's mother, Melissa, told reporters her daughter had "no life left in her."

"On Tuesday ... our lives changed completely and totally forever. My daughter was hurt by a boy who shot her in the head and took everything from our lives," she said.

A 14-year-old boy, later identified as Desmond Barnes, was also injured in the shooting. Authorities said he was shot in the thigh but was later released from a local hospital.

Police are still investigating if the boy was shot by Rollins or Gaskill while the two exchanged gunfire.

A 17-year old girl is dead and one other person was left injured from a March 7 shooting at Huffman High School in Birmingham, Alabama.

Courtlin Arrington, 17, was killed when shots were fired in a classroom, Birmingham Police Chief Orlando Wilson told WBRC. A 17-year-old male student was wounded. He was taken to the hospital and released.

Birmingham Police Department announced March 8 that a student was taken into custody in the investigation into the deadly shooting. Police said evidence, surveillance video and statements were reviewed throughout the night.

Police initially called the shooting “accidental,” but later reviewed a video that captured the deadly incident.

"We're not saying he shot her, we're not saying he didn't shoot her," the chief said. "We're asking those questions ourselves so we can determine exactly what happened."

Police responded to reports of shots fired at Marjory Stoneman Douglas High School in Parkland, Fla., around 3 p.m. on Feb. 14. Seventeen people lost their lives and 17 others were injured.

The day after the shooting, the suspected gunman, 19-year-old Nikolas Cruz, told authorities he arrived at the school with an AR-15 rifle, adding that he shot "students that he saw in the hallways and on school grounds," according to an arrest affidavit.

Cruz may plead guilty to avoid the death penalty, his lawyer reportedly said Feb. 16.

Cruz was formally charged March 7 with 17 counts each of premeditated murder and attempted murder.

A 12-year-old girl was taken into custody after police said the loaded gun she brought to Salvador B. Castro Middle School in Los Angeles accidentally discharged on Feb. 1, shooting a 15-year-old boy in the head and a 15-year-old girl in the wrist.

Police interviewed the 12-year-old student and agreed the shooting was accidental. She was booked in a juvenile detention center on suspicion of negligently discharging a firearm on school grounds.

It is unclear where the girl got the gun or why she decided to bring it to her school.

Doctors said both students who were shot are expected to recover.

Additionally, an 11-year-old boy and a 12-year-old girl were treated at the hospital and released while a 30-year-old woman, who is a school staff member, had only minor injuries, Los Angeles city police said in a statement.

A shooter opened fire at Marshall County High School in Benton, Ky., on Jan. 23, killing two people.

Students Bailey Nicole Holt and Preston Ryan Cope, both 15 years old, died.

Suspected shooter Gabriel Ross Parker, 15, was arraigned on Feb. 16, according to Kentucky State Police.

"A Marshall County Grand Jury returned an indictment on Tuesday, charging Parker with two counts of Murder and fourteen counts of First Degree Assault," KSP said.

Marshall County Circuit Clerk Tiffany Griffith told Reuters a judge entered a not guilty plea on the teen's behalf.

A 15-year-old girl was hurt in a Jan. 22 shooting at Italy High School in Italy, Texas. A 16-year-old male student was taken into custody, Ellis County police told Fox News.

In the school's cafeteria, the suspect "engaged the victim" and fired several shots with a semi-automatic handgun, Ellis County Sheriff Chuck Edge said during a press briefing.

The suspect was confronted by an Italy Independent School District staffer in the school cafeteria and took off, Edge said. Law enforcement later apprehended the suspect on school grounds.

The suspect was charged with two counts of aggravated assault with a deadly weapon, the Ellis County district attorney's office announced.

Gunman William Atchison, 21, disguised himself as a student to get inside Aztec High School in Aztec, N.M., on Dec. 7, 2017, according to authorities. Atchison was also a former student.

State police said that Atchison killed students Francisco I. Fernandez and Casey J. Marquez.

Officials said Atchison eventually shot himself, adding that the students killed were not targeted, but were at the "wrong place at the wrong time."

A man in Northern California went on a random shooting rampage on Nov. 14, 2017, killing five people and wounding at least a dozen adults and children before authorities shot and killed him.

The gunman, who was later identified as Kevin Neal, 44, rammed a car into the gates of Rancho Tehama Elementary School and shot at its portable classrooms. He repeatedly tried to get into a kindergarten classroom but quick-thinking staff locked the school down, and he eventually stormed off.

Neal reportedly targeted the elementary school as part of a long-running feud with neighbors.

A male student shot and injured a fellow student at a central Illinois high school on Sept. 20, 2017. The shooting unfolded in Mattoon High School’s cafeteria around 11:30 a.m., officials said at the time.

One female teacher intervened and successfully subdued and disarmed the gunman -- a move Mattoon Police Chief Jeff Branson said at the time was “pivotal.”

The gunman was taken into custody shortly after the incident.

A 15-year-old student opened fire on fellow classmates at a Washington state high school on Sept. 13, 2017, killing one, investigators said. Caleb Sharpe, the suspected gunman, said the student who died had bullied him.

The slain student tried to stop the teen's rampage when the gun jammed, according to The Associated Press. A school janitor was hailed a hero after he was able to subdue the alleged shooter.

Three other students were wounded in the attack. According to court documents, Sharpe told officials that he brought the two guns to school to “teach everyone a lesson about what happens when you bully others.”

A special needs teacher and a child, 8, were killed in what police said was a murder-suicide at North Park Elementary School in San Bernardino, California.

Police said Cedric Anderson walked into the school on April 10, 2017, and shot his estranged wife, Karen Elaine Smith. Two other students were also struck before Anderson killed himself, although law enforcement officials said they do not believe they were intended targets.

Jonathan Martinez was identified as the 8-year-old killed at the elementary school. A 9-year-old was injured.

Two high school students were injured after a fellow student allegedly fired a shotgun inside Liberty-Salem High School in Ohio on Jan. 20, 2017.

Logan Cole, who was 16 at the time, was shot twice but survived. Another student was grazed by a bullet. Champaign County Sheriff Matthew Melvin said the gunman intended to harm more students than he did.

Ely Serna, the accused gunman, was 17 at the time of the shooting but is being tried as an adult in Champaign County court. He has pleaded not guilty by reason of insanity.

The scene remains active, according to the sheriff's office.</s>(CNN) The 16-year-old girl wounded by an armed student at Great Mills High School in southern Maryland early this week has died, her family and authorities said Friday.

Jaelynn Willey was taken off life support on Thursday and was surrounded by her family when she passed away at 11:34 p.m., the St. Mary's County Sheriff's Office said on behalf of the family.

"It is with heavy hearts and great sadness we provide this statement," the sheriff's office said.

Willey was one of two students shot by Austin Wyatt Rollins, 17, on Tuesday in a hallway just before school began, the sheriff's office said. The other victim, a 14-year-old male student, was shot in the leg and discharged from the hospital Wednesday.

Willey's uncle, Timothy Cormier, issued a post on Facebook in her memory, calling her "the most caring, thoughtful, sweet beautiful young lady I have ever met."

The scene remains active, according to the sheriff's office.</s>When the week began, Kayla Wells, a senior at Great Mills High School in Maryland, had no plans to participate in the March for Our Lives on Saturday.

But on Tuesday morning, her classmate, 16-year-old Jaelynn Willey, was shot in the head in the hallway of their high school just before class began. Wells went home restless, unable to sleep or make sense of what had happened, and she changed her weekend plans.

“That night, I went out and got posters because I knew that I had to be there,” Wells, 17, told TIME.

Willey — a swimmer and a sister to eight siblings — was critically wounded in the shooting by 17-year-old Austin Wyatt Rollins, with whom she had a “prior relationship” that recently ended, authorities said. She died Thursday night after being taken off life support.

Wells did not know Jaelynn personally, but she said she broke down when she heard the news. “It shouldn’t happen again. It shouldn’t happen to anyone,” Wells said. “How did we become so desensitized to shootings happening?”

She organized a poster-making session on Friday night. And on Saturday morning, she was among dozens of Great Mills students and alumni who drove to Washington, D.C. to march for Willey, carrying posters that said, “It happened at my school” and “Justice for Jaelynn.”

Jillian Carty, 18, graduated from Great Mills High School last year and is now a student at Franklin Pierce University in New Hampshire. But when the shooting happened on Tuesday, she thought immediately of her younger sister at the school, and she decided to drive back home and march, calling for a comprehensive solution to stop gun violence.

“I see a lot of good points that are made with people who are pushing for gun reform, I see good points that are made by people who are pushing for mental health reform,” Carty told TIME. “I don’t see why there is any reason why they can’t combine.”

Hundreds of thousands of students are expected to participate in the march in Washington, D.C. and in sibling rallies around the country on Saturday. The movement was organized by student survivors of last month’s shooting at Marjory Stoneman Douglas High School, many of whom spoke out for Willey this week.

“We will march for you, Jaelynn Willey,” Marjory Stoneman Douglas junior Jaclyn Corin said in a tweet on Thursday. “We will march for all the students of Great Mills who will forever be traumatized because of what happened on Tuesday.”</s>iStock/Thinkstock(CHEVERLY, Md.) — A 16-year-old girl shot at her Maryland high school on Tuesday died late Thursday night after she was taken off life support, officials said.

Great Mills High School student Jaelynn Willey, 16, and a classmate were shot, allegedly by Austin Rollins, 17, in a school hallway just before classes began on Tuesday, police said. The school’s resource officer engaged Rollins and the two exchanged gunfire; Rollins was hit and later died at a hospital.

“On Tuesday, this past week, our lives changed completely and totally forever,” Willey’s mother, Melissa Willey, said at a press conference Thursday. “My daughter was hurt by a boy who shot her in the head.”

Jaelynn Willey had been on life support at University of Maryland Prince George’s Hospital Center in Cheverly, Maryland, but was brain dead.

“She will not make it,” her mother said. “We will be taking her off life support this evening.”

Jaelynn Willey was the second-oldest of nine siblings and a member of the Great Mills High School swim team, her mother said.

“It is with terribly broken hearts that we learn of the tragic news regarding Jaelynn Willey,” Maryland Governor Larry Hogan said in a statement Thursday. “No parent should ever be faced with a decision like this.”

“There are no words adequate to express our compassion for her loving family and the entire Great Mills community,” he said. “All of Maryland grieves with them, and they will remain in our thoughts and prayers.”

The second victim, a 14-year-old boy, was treated for a gunshot wound in the thigh and released on Wednesday.

Jaelynn Willey and the suspected gunman “had a prior relationship” that “recently ended,” the St. Mary’s County Sheriff’s Office said. “All indications suggest the shooting was not a random act of violence.”

“This is what we prepare for,” he said. “And this is what we pray we never have to do.”

This shooting came four days before Saturday’s March for Our Lives in nearby Washington, D.C. Thousands of students are expected to descend upon the nation’s capital to rally for gun control and safer schools in the wake of the deadly Feb. 14 shooting in Parkland, Florida.

Less than one week before Great Mills High School faced its own shooting, its students were among the thousands participating in the National School Walkout, according to local news outlet TheBayNet.com.

The walkout, which marked a month since the Parkland massacre, was organized as a call on Congress to tighten gun laws.</s>A 16-year-old girl shot at her Maryland high school on Tuesday died Thursday night after she was taken off life support, officials said.Great Mills High School student Jaelynn Willey, 16, and a classmate were shot, allegedly by Austin Rollins, 17, in a school hallway just before classes began on Tuesday, police said.

Willey, 16, died late Thursday night, hours after her parents made the heart-wrenching decision.

“As of now Jaelynn is still on life support, but she will not make it,” Jaelynn’s mom, Melissa Wiley, told reporters on Thursday. “We will be taking her off life support this evening. She has no life left in her.”

Willey was critically wounded Tuesday when officials say 17-year-old Austin Rollins shot her with his father’s legally owned firearm at Great Mills High School in St. Mary’s County.

School resource officer Blaine Gaskill responded within moments of the Great Mills shooting and opened fire.

Rollins was shot — it remains unclear whether it was by Gaskill or his own hand — and killed.

Police investigators said in a statement that “all indications suggest the shooting was not a random act of violence.”

Reports have since emerged that Jaelynn had been in a relationship with Rollins until recently.

Jaelynn was declared dead at 11:30 p.m., family said in a statement.

A YouCaring fundraiser has been set up to help the Willeys financially in their time of need.

As of Friday morning, more than $75,000 had been raised.

 Nikolas Cruz’s Brother Cries in Court as Shooting Suspect Appears at Arraignment Hearing</s>A teenage girl left brain dead after she was wounded in a school shooting in Maryland died after she was removed from life support, local officials said Friday.

The girl, 16 year old Jaelynn Willey, was shot in the head by the attacker, with whom she had had a relationship.

Another student was wounded in Tuesday's attack, and the assailant - also a student - was shot and killed by a police officer stationed at the high school in southern Maryland.

Writing on behalf of the Willey family, the St. Mary's County Sheriff's Office issued a statement "with heavy hearts and great sadness," saying that Jaelynn Willey died at 11:34 pm Thursday (0334 GMT Friday) "surrounded by her family."

Her parents told a news conference late Thursday that their daughter was brain dead and would be taken off of life support.

"My daughter was hurt by a boy who shot her in the head and took everything from us," said her mother, Melissa Willey, according to The Washington Post.

The Great Mills High School shooting came about five weeks after a massacre at a Florida high school left 14 students and three adults dead and sparked a grassroots campaign for tougher laws on gun ownership.

The shootout, in a school located just 90 minutes from the US capital, took place just days before a massive Saturday rally in downtown Washington supporting gun control.</s>March 23 (Reuters) - A 16-year-old girl shot in the head by a fellow student at a Maryland high school has died, raising the death toll from the latest U.S. school shooting to two, including the shooter, authorities said on Friday.

Jaelynn Willey's death shortly before midnight on Thursday came as hundreds of thousands of Americans were preparing to march nationwide on Saturday to press lawmakers for tighter gun controls.

The march will be led by survivors of a Florida high school shooting in February that claimed 17 lives, who have reignited efforts to tighten gun laws after decades of shooting sprees at U.S. schools and colleges. On the other side of the debate, gun rights advocates cite constitutional guarantees of the right to bear arms.

Willey, the second oldest of nine children, died surrounded by her family, the St. Mary´s County Sheriff´s Office said in a statement. "It is with heavy hearts and great sadness we provide this update," the statement said.

Willey's mother had said at a hospital in Cheverly, Maryland, that her daughter had been declared brain dead and would be taken off life support.

"My daughter was hurt by a boy who shot her in the head and took everything from our lives," she told reporters.

Austin Rollins, a 17-year-old student at Great Mills High School in southern Maryland, is suspected of shooting Willey in a hallway on Tuesday with his father's handgun, according to the sheriff's office. Willey had been in a relationship with Rollins that had recently ended.

A deputy sheriff stationed at the school confronted Rollins and they simultaneously fired at each other, according to police. Rollins was wounded and died at a hospital. The officer was unharmed.

Investigators have been uncertain over who fired a shot that hit a 14-year-old student in the leg.

An autopsy was being carried out on Rollins to determine whether he was killed by a shot fired by the officer or from a self-inflicted wound. Sheriff's spokeswoman Corporal Julie Yingling said results of the autopsy would not be released until at least next week.

The fundraising website YouCaring showed more than $80,500 of a goal of $100,000 had been raised to pay for Willey's medical expenses. (Reporting by Ian Simpson in Washington; Editing by Jonathan Oatis)
