A suspected gunman, later identified as 19-year-old Sky Bouche, allegedly opened fire at Forest High School in Ocala, Florida, on April 20. The shooting occured on the 19th anniversary of the Columbine school shooting.
At least one student was injured after the gunman shot through a classroom door, hitting a 17-year-old student in the ankle, authorities said. The student was later taken to a local hospital with a non-life-threatening injury.
A school resource officer, James Long, was hailed a hero after arresting Bouche just three minutes after he opened fire.
Bouche, a former student at the school, allegedly carried the weapon in a guitar case inside the school, authorities said.
Great Mills High School, Maryland
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.

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."
Marjory Stoneman Douglas High School, Florida
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.

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.
