Portland Police Bureau(NEW YORK) — The “hero” football coach who disarmed an alleged gunman at an Oregon high school said Saturday he “put his life on the line” for his students because he didn’t have “any other choice but to act.”Keanon Lowe, who coaches football and track and field at Parkrose High School, wrestled the alleged gunman, Angel Granados Dias, 18, to the ground when police say the suspect brought a weapon on campus Friday afternoon.“When I signed up to be a Security Guard, Football and Track & Field Coach for Parkrose High School, I did so to guide and coach young people whose shoes I had once been in,” he tweeted Saturday. “I had no idea, that I would one day have to put my life on the line like I did yesterday for my students.”Lowe said when Granados Dias allegedly went to the school and put his students in danger, there was no option but to try to stop him.“When confronted with the test the universe presented me with, I didn’t see any other choice but to act,” he continued in the tweet. “Thank God, I passed.”No one was injured in the Friday afternoon scare, police said.“I’m blessed to be alive and extremely happy that the students are safe,” Lowe tweeted.Officers apprehended Granados Dias and recovered the weapon he allegedly brought to the school. He was charged with possession of firearm in a public building, attempting to discharge a firearm at a school, reckless endangerment, and possession of a loaded firearm in a public place, police said.Students told ABC affiliate KATU-TV that Lowe, formerly a star wide receiver with the University of Oregon Ducks, saved the day.“He’s a hero,” one student told KATU on Friday.A police sergeant said the shooting threat ended with the “best-case scenario.”“The staff members from all accounts did an excellent job,” said Portland Police Sergeant Brad Yakots.Police said the investigation was ongoing.But Lowe said the experience has been a blur, and has made him reflect on life and gun violence in schools.“I’ve spent the last 24 hours being more appreciative of my family and realizing we have a serious problem,” he said.“I’m not sure what’s next, I haven’t had the time to really think about it,” he added. “But I am sure I want to be a part of the solution to school gun violence.” I’m blessed to be alive and extremely happy that the students are safe. I’m not sure what’s next, I haven’t had the time to really think about it. But I am sure I want to be a part of the solution to school gun violence.
