LANSING, Mich. (Great Lakes News) – Tuesday’s deadly school shooting at Oxford High School has Michigan Attorney General Dana Nessel calling for stricter gun laws, including raising the age limit to own or possess a gun in Michigan.

However, the alleged Oxford High School shooter already broke a law currently on the books when he brought the gun to school. He is 15-years-old; Michigan residents must be 18-years or older to own or possess a gun in public.
