			 Karl Pierson, 18, entered Arapahoe High School in a Denver suburb 
			around midday on Friday brandishing a shot gun and asked fellow 
			students about the location of a teacher. He then shot a 15-year-old 
			girl who was nearby, a county official said. 
 			He was later found inside a classroom with an apparently 
			self-inflicted gunshot wound. The teacher, who quickly fled the 
			school, was unharmed.
 			Fellow students said Pierson was a smart and likeable member of the 
			school's track team and debate club.
 			Arapahoe County Sheriff Grayson Robinson said detectives were 
			investigating "revenge" as a possible motive, but did not elaborate, 
			though investigators believed the youth acted alone.
 			Police said they knew of no prior discipline problems.
 			The shooting in the Denver suburb of Centennial took place just 8 
			miles from the scene of one of the deadliest school massacres in 
			U.S. history, Columbine High School, where two students gunned down 
			13 classmates and staff before killing themselves in 1999. 			
			
			 
 			There was no indication the incident was related to the anniversary 
			on Saturday of last year's Sandy Hook Elementary School shooting in 
			Newtown, Connecticut, in which a gunman massacred 20 children and 
			six adults before killing himself, Robinson said.
 			"I believe the shooter knew that deputy sheriffs were immediately 
			about to engage him, and I believe that shooter took his life 
			because he knew that he had been found," the sheriff told a news 
			conference on Friday.
 			He said a firebomb-like device was detonated inside the school by 
			the suspect, but a second such incendiary device did not go off and 
			was rendered harmless by authorities.
 			SHAKING, CRYING
 			Nearby businesses were evacuated as dozens of police arrived at the 
			scene with guns drawn. They never fired their weapons as they 
			pursued the gunman and evacuated the school.
 			Reports and images from the school show frenzy and fear among the 
			students. Some could be seen being funneled out with their hands 
			raised onto a track field where they were being patted down by 
			police.

			Holly Schaefer, an 18-year-old senior, said she saw blood on the 
			hallway floor as students were being escorted out of the building.
 			Whitney Riley, 15, told CNN she and several other students and 
			teachers hid in a utility room after hearing gunfire and did not 
			come out until police arrived.
 			"We were shaking. We were crying. We were freaking out. I had a girl 
			biting my arm," she said. "We stayed quiet and we heard a whole 
			bunch of sounds. We heard people yelling. We heard walkie-talkies."
 			Colorado Governor John Hickenlooper, who pushed through tougher 
			firearms legislation this year following the Newtown shooting and 
			last year's attack in a Colorado movie theater that killed 12 
			people, called the shooting an "all-too-familiar sequence, where you 
			have gunshots and parents racing to the school and unspeakable 
			horror in a place of learning."
 			Authorities said they planned to conduct searches of the suspected 
			gunman's vehicle, which was left parked at the school, and two homes 
			owned by his parents.
 			The local ABC News affiliate in Denver reported the suspected gunman 
			was upset after being kicked off the debate squad.
 			Arapahoe senior Frank Woronoff told CNN the gunman had recently been 
			"demoted" on the debate team and the teacher he was said to be 
			targeting was its faculty adviser and the school's librarian.
