A survivor of arguably the most infamous school shooting in history has criticized the punishments of the parents of Ethan Crumbley.

In an interview with Fox & Friends on Wednesday, a Columbine High School survivor said the prison sentences for Michigan high school shooter Ethan Crumbley's parents set a "dangerous precedent" as they removed responsibility from the actual criminal, who "knew what he was doing."

Craig Scott, who lost his sister, Rachel, in the infamous Columbine massacre, explained why he disagrees with the parents prison sentencing, arguing they couldn't have predicted their son's actions.

"I speak at a lot of schools across the country and deal with emotional resilience and try to affect the cultures of schools and students' lives by inspiring kindness and resilience, and I think this is a bad and dangerous precedent to take the blame on a teenager who knew what he was doing was wrong", Scott, now 41, added.

"The mother of one of the shooters is now friends with my family, with my mother," he continued.

"He had a dark motivation for wanting to be infamous. And now they're giving 10 to 15 years to the parents, and I think it's wrong", Scott finished.

Ethan Crumbley, 15 at the time, went on a mass shooting spree at Oxford High School in Michigan in November of 2021, killing four and injuring seven others before being taken into custody.

Now, his parents, Jennifer and James Crumbley, have become the first parents in the US to be held criminally liable for a mass shooting executed by their child.

They were each sentenced to 10-15 years in prison.

Prosecutors allege the Crumbley's could have prevented the incident when they stopped by the school to meet with counselors on the same day and prior to the shooting to discuss disturbing content Ethan had drawn in class.

Scott went on to say that the teenager admitted in open court that he lied a lot. He was lying to his parents; he was lying to everyone around him; and ultimately, it was his decision that led to a crime he knew was wrong.
