Gunman wounds 4 in Ohio school lunch room before K-9 unit catches him

A teenage gunman burst into the lunch room of an Ohio school Monday morning and opened fire, wounding four students before a K-9 unit caught him, local media report.

The shooting unfolded at Madison Junior/Senior High School in Butler County, where the 14-year-old suspect is a student. He now faces charges including attempted murder and making terrorist threats. It's not clear whether he targeted certain students or fired at random, Sheriff Richard Jones said.

The suspect bolted from the school after the shooting, got rid of his gun, and ran into a field before the K-9 unit caught him, the Journal-News reports. Investigators said he used a .380 caliber handgun, according to Fox 19.

Two students were hurt by gunshots and two others apparently by shrapnel, Butler County Chief Deputy Anthony Dwyer said. One of the students is 15 and the others are 14. Each is in stable condition in the hospital.

The school lifted its lockdown after the sheriff gave the all-clear. "It was painful... hard to concentrate," parent Ken Gairland said as he drove to pick up his sons.

At least one of the victims was shot in the leg. The other injuries appear to be more serious, but not life-threatening.

At least two AirCare helicopters flew to the school. "I just cleared the scene there and it is hectic," Rodney Muterspaw, police chief of nearly Middletown, said.
