A majority of Michigan voters support charging the parents of Oxford High School shooting suspect Ethan Crumbley for the role they have been accused of playing in their son's deadly actions, according to a local poll.

Crumbley, 15, is suspected of fatally shooting four students and injuring seven others at Oxford High School on Nov. 30, 2021. Oakland County prosecutor Karen McDonald charged his parents, James and Jennifer Crumbley, with four counts of involuntary manslaughter each. 

Nearly three-fourths of likely Michigan voters support charges against the parents, while less than 9% of likely voters oppose charges. About 17% don't know how they feel about the charges, a recent poll from WDIV/ Detroit News shows.

More local results from those within the Metro Detroit area, specifically, show even stronger results in favor of charges against James and Jennifer Crumbley, with more than 86% of respondents supporting charges against the parents and 7% opposing them.

The Glengariff Group, Inc. conducted the Michigan statewide poll of 600 likely 2022 general election voters. The survey has a margin of error of +/-4.0% with a 95% level of confidence, and was conducted via phone between Jan. 3 and Jan. 7, 2022.

Authorities say Ethan Crumbley used a pistol his father, James Crumbley, bought on Black Friday, Nov. 26, 2021, in the Nov. 30 shooting.

Both parents pleaded not guilty at their arraignment, where Jennifer Crumbley appeared to tear up while Judge Julie Nicholson read their charges aloud. The two are being held on $500,000 bond each, or a total of $1 million.

McDonald also revealed in December that school officials met with Crumbley and his parents to discuss the violent drawings just hours before the deadly rampage. The 15-year-old suspect was able to convince them during the meeting that the concerning drawings were for a "video game." His parents "flatly refused" to take their son home.

Oxford Community Schools superintendent Tim Throne said in a letter to the Oxford High School community that on the morning of Nov. 30, "a teacher observed concerning drawings and written statements" from Crumbley, which that teacher then "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," Throne said in the letter.

He added that "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," Thorne added.

A third party is investigating the school’s handling of Crumbley ahead of the shooting. The school district denied the district attorney's request to conduct an independent investigation into the matter.

The four students who died in the shooting are 16-year-old Tate Myre, 14-year-old Hana St. Juliana, 17-year-old Madisyn Baldwin and 15-year-old Justin Shilling.
