CHARDON, Ohio - Teacher Joe Ricci had just begun class at his suburban Cleveland high school when he heard shots and slammed the door to his classroom, yelling, "Lockdown!" to students.
A few minutes later, he heard moaning outside, opened the door and pulled in student Nick Walczak who had been shot several times, according to a student whose sister was in Ricci's classroom.
In the end, a teenager who opened fire in the school's cafeteria on Monday killed one student and wounded four others before he was captured, authorities said.
The teen was identified as TJ Lane by his family's lawyer, according to WKYC-TV in Cleveland, and was also named by eyewitnesses to the shooting.
FBI officials would not comment on a motive. And Police Chief Tim McKenna said authorities "have a lot of homework to do yet" in their investigation of the shooting, which sent students screaming through the halls at the start of the school day at 1,100-student Chardon High.
Two of the wounded were listed in critical condition, and another was in serious condition.
A news conference was planned for midmorning on Tuesday.
Gov. John Kasich has ordered flags at the Ohio Statehouse flown at half-staff in honor of slain student Daniel Parmertor. Flags in Geauga County will also be lowered.
Parmertor was an aspiring computer repairman who was waiting in the cafeteria for the bus for his daily 15-minute ride to a vocational school.
His teacher at the Auburn Career School had no idea why Parmertor, "a very good young man, very quiet," had been targeted, said Auburn superintendent Maggie Lynch.
"We are shocked by this senseless tragedy," Parmertor's family said in a statement. "Danny was a bright young boy who had a bright future ahead of him."
A student who saw the attack up close said it appeared that the gunman targeted a group of students sitting together and that the one who was killed was gunned down while trying to duck under a cafeteria table.
Lawyer Robert Farinacci, who is representing Lane and his family, told WKYC-TV that Lane's family was "devastated" by the shootings and offered their "most heartfelt and sincere condolences" to Parmertor's family. He said they also were praying for the wounded students.
When asked about Lane, Farinacci described him as "a fairly quiet and good kid" with grades that are "pretty impressive."
The FBI said the gunman was arrested near his car a half-mile from Chardon. He was not immediately charged.
An education official said the suspected shooter is a Lake Academy student, not a student at Chardon High. Brian Bontempo declined to answer any questions about the student. Bontempo is the superintendent of the Lake County Educational Service Center, which operates the academy.
The alternative school in Willoughby serves 7th through 12th grades. Students may have been referred to the school because of academic or behavioral problems, among other issues.
