The suspect in the deadly shooting at a Michigan high school reportedly told school guidance counselors that the alarming drawings his teacher discovered the morning of Tuesday's massacre were for a video game he was designing, school officials said.

Hours before authorities allege 15-year-old sophomore Ethan Crumbley fired his father's semi-automatic handgun in the hallway of Oxford High School, killing four and wounding seven, a teacher saw a note on his desk with a drawing of a semi-automatic handgun pointing at the words, "The thoughts won't stop, help me," prosecutors said.

Another section depicted a drawing of a bullet with the words "Blood everywhere" above it, and a drawing of a bleeding person who appeared to have been shot twice, according to prosecutors.
