UPDATED 8/21/08 7:13 p.m.: Knoxville (WVLT) - Students say Central High's cafeteria is always noisy before classes start.
So when they hear the pop. "It sounded like a toy gun, no one really took it for anything," says Central High student Brooklyn.
Until they saw 15-year-old Ryan McDonald fall.
We walked over there, and then he was laying dead--and then he started having little spasms," Brooklyn says.
"Everybody like went running and screaming," Carly's one to head to the office to call 911.
Two minutes later, Knoxville Police are on-scene and Central High is on lock down.
"The shooter sprinted out, I didn't get a good look at him," says Brooklyn.
"At 8:17, the suspect was in custody, so within six minutes of the time the incident occurred, the suspect had been arrested," says Knoxville Deputy Police Chief Bill Roehl.
And a weapon recovered, three blocks away. The suspect was identified as 15-year-old-Jamar Silar.
Ryan McDonald would die of his wound in UT Medical Center's E.R.
Quickly, it's clear "Both the suspect and the victim knew each other. We don't know the particulars of why it escalated to the situation that occurred today," says Chief Deputy Roehl.
But it's enough to pull Central, Halls High, and two middle and elementary schools off lock down.
"When we first walked into the chorus room, everybody was praying in a big circle, holding hands in prayer, so that's the most re-assuring thing I've had all day," says Central High student Haley Hammet.
"Obviously, class will be dismissed for the rest of the day here at Central High school, and we are making sure that parents are notified," said Knox County Superintendent Dr. Jim McIntyre.
By late Thursday morning, parents and children are reuniting at Central Baptist Church in Fountain City, where counseling was available.
"She's safe, she never was in harm's way," coincidentally, Pastor Chris Buice's daughter is a Central Student.
After the shootings and killings at his church, Tennessee Valley Unitarian Universalist barely 3 weeks ago, he knew his place was here. "Most tangibly, I'm aware of how I've benefited from people reaching out to me and our church in time of need, and it just brought home the importance of being there for people, in the time of need."
