The young suspect in the Oxford, Michigan, school shooting has been charged with terrorism and first-degree murder. Although he is 15 years old, he is being charged as an adult. Ethan Crumbley was arraigned Wednesday on four counts of murder. His father reportedly bought the gun used in the shootings — a 9mm Sig Sauer — just last Friday. The teen posted a photo of the weapon with the caption, “Just got my new beauty today.” Classmate Isaac Fantich said that Crumbley often looked “depressed.”
