Brian Schaeffer of the Spokane Fire Department told reporters that one person died in the shooting Wednesday morning at Freeman High School in Rockford, south of Spokane.
According to KHQ, the custodian approached Sharpe and "ordered him to surrender". Public schools in Spokane also went into lockdown as a precautionary measure.
The three other victims who were shot are reportedly in stable condition. He says he saw the student at school with a duffel bag.
The sheriff said a deputy who works as a school resource officer arrived shortly thereafter and took the shooter into custody.
The Associated Press doesn't normally name adolescent suspects however is doing as such on account of the seriousness of the allegations and on the grounds that Sharpe's name was discharged in openly accessible archives and was broadly utilized as a part of nearby media. "For the first time in I don't know how many years [Bellingham School District] increased counselors at all of our middle and high schools", Baker said.
Spokane County Sheriff Ozzie Knezovich said Thursday that Caleb Sharpe used a handgun to kill a classmate and wound three others after the rifle malfunctioned.
Parent Brandi Albert said, "I always thought this is such a great school and you would never think that anything like this would ever happen here". Investigators have said little about his motives so far.
After the shooting, a two-lane road into the community of about 500 people near the Idaho border was clogged with vehicles. "I was about to put my things away, and I just heard a loud 'pop, ' and I just looked behind me and, the shooter, he was just walking down the hall very calmly".
He called me and said, Mom, there are gunshots.
"It's been incredible, within probably 15-20 minutes of hearing about it, I'd already received a phone call, I'd already received a text message saying that their school is OK", she said.
She says classes were about to begin because it's a "late start" day.
Police searched the high school's rooms for any additional threats, the sheriff's office said on Twitter.
The United States has had an average of 52 school shooting incidents a year since a gunman killed 26 young children and educators in Newtown, Connecticut, in 2012, according to Everytown for Gun Safety, a gun-control group founded in response to that massacre. She commended the school district for its communication with parents.
