The accused Michigan high school shooter convinced school officials ahead of the deadly rampage that violent drawings he made were for a "video game," a letter released Saturday by the school shows.  

"On the morning of Nov. 30, a teacher observed concerning drawings and written statements that have been detailed in media reports, which the teacher reported to school counselors and the Dean of students. The student was immediately removed from the classroom and brought to the guidance counselor’s office where he claimed the drawing was part of a video game he was designing and informed counselors that he planned to pursue video game design as a career," a letter sent to the Oxford High School community from Oxford Community Schools superintendent Tim Thorne on Saturday states.

Accused shooter Ethan Crumbley, 15, and his parents met with school officials just hours before he allegedly opened fire on peers and school employees, killing four students and injuring seven other people. 

"At no time did counselors believe the student might harm others based on his behavior, responses and demeanor, which appeared calm. In addition, despite media reports, whether or not the gun was in his backpack has not been confirmed by law enforcement to our knowledge nor by our investigation at this time," the letter, published by WXYZ, said.

The letter added that Crumbley’s parents were told to take their son home that day, but "they flatly refused and left without their son, apparently to return to work." The school also reportedly told the parents they had 48 hours to find counseling for their son or "the school would contact Child Protective Services." 

School officials were also allegedly not made aware of the family’s recent gun purchase, which was reportedly used in the shooting, and Crumbley was returned to class. 

"While we understand this decision has caused anger, confusion and prompted understandable questioning, the counselors made a judgment based on their professional training and clinical experience and did not have all the facts we now know. Our counselors are deeply committed longstanding school members who have dedicated their lives to supporting students and addressing student mental health and behavioral issues," the letter continued.

A third party will investigate how Crumbley interacted with the school employees and peers ahead of the shooting, according to the letter.
