Videos Found on Ethan Crumbley's Phone 'Horrendously Disturbing,' Oakland Co. Sheriff Says

The sheriff in Oakland County, Michigan said on Thursday that videos found on Ethan Crumbley's phone the night before the Oxford High School shooting were "horrendously disturbing."

Oakland County Sheriff Michael Bouchard made his comments during an interview with CNN's New Day when asked about videos that were found on Crumbley's phone that were recorded the night before the shooting.

"Obviously [he] talks about what he intends to do and the kind of things he's thinking about," Bouchard said. "It's just chilling."

On Wednesday, 15-year-old Crumbley was identified as the Oxford High School shooter who fatally shot four students. Crumbley was arrested shortly after the incident and Oakland County prosecutor Karen D. McDonald announced that he will be charged as an adult with first-degree murder and terrorism.

The comments by Bouchard come shortly after Crumbley's arraignment where Oakland County Lieutenant Tim Willis revealed that videos, recorded before the shooting, were recovered from his cellphone. According to Willis, police discovered "a video made by him the night before the incident wherein he talked about shooting and killing students the next day at Oxford High School."

Willis continued, "Further, a journal was recovered from Ethan's backpack also detailing his desire to shoot up a school to include murdering students."

During a press conference on Wednesday, three students that were killed in the shooting were identified as Hana St. Juliana, 14; Madisyn Baldwin, 17; and Tate Myre, 16. A fourth student was later identified Justin Shilling, 17, who succumbed to his injuries at the McLaren Oakland Hospital.

Several other students were injured during the shooting, according to police.

On Wednesday, McDonald said that investigators are "confident it was premeditated," and noted that they have recovered a "mountain of digital evidence." McDonald also noted that the gun Crumbley used in the shooting was purchased by his father just a few days before, adding that her office was considering filing charges against his parents.

Officials also said that Crumbley and his parents met with teachers at the high school on the day of the shooting after he exhibited "concerning behavior." While appearing on CNN's New Day, Bouchard discussed the meeting Crumbley and his parents had with the teacher and said that "it was ultimately determined that [Crumbley] could go back into class," after the meeting.

"So that's obviously part of our investigation. We were never informed of either meeting prior to the shooting or that there were any concerns about behavior," Bouchard said.

Crumbley has pleaded not guilty to the charges and faces life in prison if convicted.

Newsweek reached out to the Oakland County Sheriff's Office for comment.
