According to prosecutors, James Crumbley purchased the Sig Sauer 9-mm. semi-automatic handgun, the weapon allegedly used by his son, four days before the shooting. A store employee told investigators that Ethan Crumbley was with his father at the time of the purchase. The same day, Ethan Crumbley posted photos of the gun to social media with the caption, "Just got my new beauty today," McDonald said.
The next day, Jennifer Crumbley posted to social media suggesting that she and Ethan were testing out the gun, which she referred to as "his new Christmas present," McDonald said.
On Nov. 21, McDonald said that a teacher at Oxford High School observed Ethan Crumbley searching online for ammunition with his cellphone during class, and reported it to school officials, who informed Jennifer Crumbley but received no response from either parent.
The same day, McDonald said that Jennifer Crumbley exchanged text messages with her son about the reported incident, including one that read: "LOL I'm not mad at you, you have to learn not to get caught."
On the morning of the shooting, a teacher saw a note on Ethan Crumbley's desk that including a drawing of a semi-automatic handgun next to the words, "The thoughts won't stop, help me," and a bullet below the words "blood everywhere." The note also included drawings of figures with gunshot wounds, as well as the phrases "my life is useless" and "the world is dead."
The teacher was so alarmed she took a photo of the note with her cellphone. Jennifer and James Crumbley were immediately summoned to the school, McDonald said, and a school counselor removed Ethan Crumbley from class to meet with his parents. Ethan removed the note from his backpack, but it had already been altered, with the images of the gun and disturbing phrases "scratched out," McDonald said.
School officials told Jennifer and James Crumbley that they were required to find counseling for their son within 48 hours. McDonald said that both parents "failed to ask their son if he had his gun with him" and did not inspect his backpack. Prosecutors believe that the gun Crumbley allegedly used in the shooting was in his backpack at the meeting.
James and Jennifer Crumbley "resisted the idea of their son leaving the school at that time." They left the school, and he returned to the classroom.
Hours later, amid news of an active shooter at the school, Jennifer Crumbley texted her son: "Ethan, don't do it."
