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.
Last week, authorities once again rushed to the scene of a deadly shooting at a high school in Parkland, Fla. The massacre marked the 25th fatal shooting at a U.S. elementary, middle or high school since — and including — Columbine in 1999.
Read on for more details, and a look at other school shootings that have taken place within the last year.
Marjory Stoneman Douglas High School, Florida
Police responded to reports of shots fired at Marjory Stoneman Douglas High School in Parkland, Fla., around 3 p.m. on Feb. 14.
"There are numerous fatalities," Broward County Superintendent Robert Runcie said. "It is a horrific situation. It is a horrible day for us."
The suspect was first taken to the hospital and then brought to Broward County Jail, where he was questioned for several hours. Cruz was later charged with 17 counts of premeditated murder.
The day after the shooting, 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.
Salvador B. Castro Middle School, California
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.
Marshall County High School, Kentucky
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.
Italy High School, Texas
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.
Aztec High School, New Mexico
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."
Rancho Tehama Elementary School, California
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.
Mattoon High School, Illinois
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.
Freeman High School, Washington
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.
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.”
North Park Elementary School, California
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.
Liberty-Salem High School, Ohio
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.
