A Utah mother and father who followed their son to school and pulled a shotgun from his hand after he fired a round into a classroom ceiling likely prevented bloodshed, police said.
The teen's parents acted quickly on their intuition after they noticed guns were missing from their home.
They arrived the school shortly after the boy entered the classroom. No one was injured but the blast left a hole the size of a small plate, Bountiful Police Chief Tom Ross said.
The boy also pointed the shotgun at his own neck, Ross said.
The boy didn't say a word as a teacher and one of 26 students tried to talk him out of firing again, giving his parents a few extra seconds to arrive.
The mother took the gun out of his hand and the father pulled the boy out of the room and into a hallway, police said.
Police Lt. Dave Edwards said the father's talk with his son before he left for school and the mother's instinct that something was wrong motivated them to head to the campus after they discovered the handgun and shotgun were missing.
"Thank goodness they did not wait and went to the school to find him," Edwards said.
Police believe the teen hid the weapons and two boxes of ammunition under his long jacket as he walked to Mueller Park Junior High.
He did not point the shotgun at any other students.
Students returning to classes Friday at the school found hearts printed with messages such as "You are brave" and "Stand tall" on their lockers.
The school pep band played in the lobby and counselor s were available to talk, said Chris Williams, a spokesman for the school district.
The students who talked to the boy during the shooting is his friend, Williams said.
Investigators said they have yet to uncover his motive and were searching his phone and computer for clues.
Police said the boy had walked to Mueller Park Junior High with the shotgun and two boxes of ammo under a long trench coat-type jacket, concealing the weapons.
The suspect, whose name is being withheld because he's a juvenile, has been charged on suspicion of two charges of theft of a firearm and two counts of taking a weapon into a school.
Parents spent hours waiting for their children after the shooting as police searched the school to make sure it was safe then sent students in small groups to reunite with parents waiting at a nearby church.
Student Dan Fowers, 15, said the teenager with the guns came into a classroom minutes after class began and fired one round from a shotgun into the ceiling before a woman grabbed the gun and told him to stop.
Fowers said the woman threw the gun on the ground and pulled the boy back into a hallway.
"It was really scary," Fowers said. "The look on his face, it kind of looked like he wanted to do some damage." He said students in the classroom dived under their desks, as they'd been taught during lockdown drills, with some screaming and crying.
As the parents intervened, a teacher called 911 and a police officer who happened to be down the street arrived and took custody of the student soon after, police said.
The school, about 11 miles north of Salt Lake City, remained on lockdown as more than 100 officers went room-by-room through the building to ensure it was safe.
