A teen accused of killing four students and wounding seven others at a Michigan high school last year pleaded guilty Monday to all charges against him in what prosecutors are calling a landmark case.
Ethan Crumbley pleaded guilty to one count of terrorism causing death, four counts of first-degree murder and 19 other charges stemming from the November 30 mass shooting at Oxford High School.
“We are not aware of any other case anywhere in the country where a mass shooter has been convicted of terrorism on state charges,” Oakland County Prosecutor Karen McDonald said.
