Shortly after the charges were announced, James and Jennifer Crumbley could not be located by law enforcement; however, according to the Detroit News, the couple’s attorney says they’ve been out of town since the shooting for their safety and will return to the area to be prosecuted.

During Friday’s press conference, McDonald says the parents knew their 15-year-old son Ethan Crumbley was disturbed. The Oxford High School teen was charged Wednesday with multiple felony counts, accused of shooting to death four classmates and injuring several others.

McDonald says a meeting the morning of the shooting between the suspect, his parents, and school officials was about something alarming.

“Ethan Crumbley’s teacher came upon a note on Ethan’s desk, which alarmed her to the point that she took a picture of it on her cell phone. The note contained the following a drawing of a semi-automated handgun pointed at the words “the thoughts won’t stop, help me.” In another section of the note was the drawing of a bullet with the following words above that bullet, “blood everywhere,” said McDonald.

McDonald says the words had been scribbled over before the meeting with his parents, but after which, Ethan was allowed to return to class. A couple of hours later, he allegedly opened fire on his classmates.

McDonald says the gun used in the shootings was purchased by James Crumbley the Friday prior, and Ethan was present with him at the gun shop. Around that time, Ethan posted a photo of the gun and a message on social media.

“Just got I knew beauty today, including an emoji with hearts,” McDonald said.

McDonald says there was a whole reason to believe Ethan Crumbley was disturbed and dangerous; that’s how she determined the charges against the parents, which carries 15 years.

As of 7 pm Friday, law enforcement is still searching for the Crumbley’s.
