FBI agent Scott Wilson said after Monday morning's shooting that there was one suspected culprit. He would not discuss the extent of the students' injuries, according to the Associated Press. Erin Knife, the civil deputy with the Geauga County Sheriff's office, said the shooting was reported around 7.30am at Chardon High School about 30 miles east of Cleveland. Knife said she did not yet know the number of victims. Chardon schools superintendent Joseph Bergant told local media the shooter was believed to be a student. A local newspaper, the Cleveland Plain Dealer, quoted local officials as confirming that four students were injured - three boys and a girl. The newspaper said four ambulances were waiting at the door of the high school at 8.15am. There were unconfirmed reports that the a teacher had given chase to the gunman. Jeannette Roth, a mother who had heard from her son Joshua, a junior, told the Plain Dealer the shooting happened while students were eating breakfast in the cafeteria and waiting for first period. Suddenly, a boy "stood up and started shooting, and then it was chaos," she said. A parent, Jessica Bryant, also told the Plain Dealer that the shooting happened in the cafeteria. She said her daughter, Allison, witnessed the shootings and had told her by text message. The station said there were reports of students barricading themselves in rooms in the school. Cleveland's MetroHealth System dispatched a medical helicopter to the high school, a spokesman said. Schools in the area were locked down. Television news footage showed anxious parents escorting children away from a school building, and multiple ambulances could be seen outside. Chardon is a city of about 5,100 in north-east Ohio, about 30 miles east of Cleveland. About 1,100 students attend the high school.
