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.
Authorities are investigating reports of shots fired Wednesday at a high school in Parkland, Florida.
Read on for more details, and a look at other school shootings that have taken place in the last year.
Marjory Stoneman Douglas High School, Florida
Police are responding to reports of shots fired at Marjory Stoneman Douglas High School in Parkland, Florida.
The Broward County Sheriff’s Office said in a tweet Wednesday they were responding to reports of an active shooter at the high school and at least 20 people have been injured, WSVN 7 News reported.
“We are receiving reports of possible multiple injuries,” Broward County Public School District confirmed on Twitter Wednesday afternoon. “Law enforcement is on site.”
The school is currently on lockdown, Coral Springs Police said, instructing students and faculty members to remain barricaded inside until police can reach them.
The shooter is still at large, police said.
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, 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. A total of 20 people were injured, two of whom died, Kentucky State Police said.
The 15-year-old shooter has been charged as an adult with two counts of murder and 12 counts of first-degree assault.
The shooting began around 8 a.m. when the teenager entered the school with a handgun, authorities said.
Students Bailey Nicole Holt and Preston Ryan Copet, both 15 years old, died.
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, he told media.
The sheriff also said he is “not aware of a motive at this time,” although student Cassie Shook claimed that the suspect has previously been violent at the school.
The suspect was charged with two counts of aggravated assault with a deadly weapon, the Ellis County district attorney’s office announced.
Shook said the girl who was shot had moved to the school district a few months earlier. She said the girl had briefly dated the suspect, but that she did not know much about her.
“I did know that the guy that was shooting was mad at the girl because she had left him for somebody else,” Danaisia McCowan claimed while speaking to FOX4. “So he shot at one guy and missed him, and then he shot at her.”
Ellis County sheriff’s Sgt. Joe Fitzgerald told The Associated Press that authorities would inquire about any dating history involving the two.
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.
