text: Timeline of shooting at Butler High School 
   
   One student was shot and killed at Butler high school early Monday morning after an argument in the hallway. ||||| A North Carolina high school student shot and killed a fellow student during a fight in a crowded school hallway Monday, officials said, prompting a lockdown and generating an atmosphere of chaos and fear as dozens of parents rushed to the school to make sure their children were safe. 
   
   The student accused of firing the fatal shot was arrested quickly as investigators secured the campus at Butler High School in Matthews, about 12 miles (19 kms) southeast of Charlotte, said Matthews Police Department Capt. Stason Tyrrell. Students remained inside with the school on lockdown for about two hours after the shooting. 
   
   The male student who was shot died at a hospital, Tyrrell said. He said the suspect, also male, was quickly taken into custody by a school resource officer as others rushed to the scene as backup. Investigators have the weapon used, but have not said what it is. Neither the suspect nor the victim's names or ages were immediately released. 
   
   "We were able to review the surveillance video of the shooting, which was a fight between the two students," Tyrrell said, describing it as an "isolated incident." 
   
   Tyrrell said the shooting happened in a hallway as crowds of students arrived for the day. Charlotte-Mecklenburg Schools Superintendent Clayton Wilcox said that many students witnessed the shooting, and counselors and psychologists were available. 
   
   "There were many kids in the hallway when this happened," he said. 
   
   "We're incredibly saddened by the fact that we had a loss of life on one of our campuses today. What makes it doubly difficult is that it was one of our students who was the shooter," he said. 
   
   While police have not confirmed what kind of gun was used, Wilcox said: "I don't know how a young person gets a handgun in the state of North Carolina." He said the system was reviewing its security procedures. 
   
   By late morning, school officials said that the lockdown was lifted and families could pick up students at the main entrance. Classes were proceeding for students who remained on campus. The diverse student body of about 2,000 at the school in North Carolina's most populous county is about one-third white, one-third African-American and one-quarter Hispanic. 
   
   Before the lockdown was lifted, dozens of parents gathered outside of the school to await word on the students. Multiple parents told local television channels that they felt confused and unsure about where to meet with their children. 
   
   Television footage showed students streaming out, with many crying and hugging parents.

target: – A fight in a high school hallway led to an all too familiar outcome Monday morning: a shooting that left a student dead. But Butler High School in Matthews, NC, also is drawing attention for its decision to resume classes less than two hours after the altercation. Police say two male students fought in a crowded hallway as students were arriving for the day, reports the AP. One student shot the other, who died at the hospital, and the alleged shooter is in custody, reports WRAL. A junior at the school tells the Charlotte Observer that students were ordered into the nearest classroom for about 90 minutes, then allowed to proceed to their scheduled class once the lockdown was lifted. “They’re changing classes during an active crime scene,” says one parent critical of the decision to resume a normal school day. It appears to have been optional, however. After police gave the all-clear, the school district informed parents they could pick up their children at the high school, adding that "classes will proceed on campus today for students remaining on campus." Police are still investigating how the shooter was able to bring the gun into the school itself. (Authorities say this would-be school shooter appears to have been foiled by his own gun.)
