A 14-year-old male student shot two other male teen students in the cafeteria of a Butler County school about 11:30 a.m. Monday.

Two other students were injured either by shrapnel or while trying to get out of the shooting area at the Madison Jr/Sr High School in Madison Township, Butler County Sheriff Rick Jones said.

The two boys shot, Cameron Smith, 15, Cooper Caffrey, 14, are in stable condition and the shooter is in custody. The boys’ injuries are not considered to be life-threatening, Jones said.

“You see these things all over the country,” Jones said. “You think it can’t happen to you but it does.”

Jones said the shooter used what appears to be 380-caliber handgun. He said the shooter ran from the school but is in custody and the weapon has been recovered.

Jones said the investigators have an idea of the shooter’s motive but are not releasing it yet.

The two others injured were Bryant Murray, 14, and  Katherine Doucette, 14.

The two struck by gunshots, Smith and Caffrey, were taken to Miami Valley Dayton hospital via medical helicopter.

The trauma team at the hospital is continuing to evaluate the teens, said Sharon Howard, site manager for public and community relations at the hospital.

Howard said the other two injured in the incident, Doucette and Murray, were not brought to Miami Valley Dayton.

All schools in the district in Butler County’s Madison Local School District were placed on lockdown after the shooting. The lockdown was lifted shortly after 12:45 p.m.

Roads to the school were backed up with parents and relatives trying to get to the school to pick up students.

Bob Hollister, of Trenton, whose grandson attends the school, said he had been sitting in his daughter’s van for about 45 minutes when the lockdown was lifted. He has another grandchild in grade school. He described last few hours as “chaotic.”

When he first arrived, Hollister said he saw police with shotguns and assault rifles.

Zayd Ahmed, an 11th-grader, says it is surreal that shooter was a 14-year-old.

Ahmed was in the library printing a resume assignment for class. He said the library is real close to the lunch room. When he heard shots he and other students huddled in storage closet. They didn’t know what was happening for  about an hour, Ahmed said.

Madison Local Schools is a district of about 1,500 students overall. The junior/senior high school has about 750 students, according to the school’s webpage.

Middletown schools and Cincinnati State’s Middletown campus were also placed on lockdown following the shooting.

Middletown City Schools lifted their “soft lockdown” just before 12:40 p.m.

In the not-so-distant past, there was no such thing as a school-shooting drill. And then, it became common for students to practice going on lockdown, huddling together in their classrooms, barricading doors and windows.

Now, most trainings are a little more proactive. Students are taught to get away if they can, but if they can’t, they’re encouraged to fight back– to throw books or chairs, whatever they can do to stop an assailant.

In 2007, Ohio passed a law requiring schools to file safety plans with the state. It’s the what-if blueprint for any kind of emergency – a tornado, an oil spill, a nearby train wreck or, as in Monday’s case, a shooting.

Those plans are online and accessible to law enforcement, so when officers are responding to a scene, they have a better idea what to expect.

Each plan for each district is different, said Ohio Attorney General’s Office spokesman Dan Tierney, created in conjunction with police, firefighters and other first responders.

“The important thing was to get the community partners involved,” Tierney said. “One-size-fits-all is not going to work in the state of Ohio.”

The advocacy group Everytown for Gun Safety says there have been at least 168 shootings at schools in the U.S. since 2013. In Ohio, the group counts:
