Oakland County Prosecutor Karen McDonald is asking a judge to refuse the Oxford High School shooter’s request to withdraw his guilty pleas to murder and other charges.

In filings with the court, the prosecution argues the shooter was fully aware of the consequences of his pleas, which resulted in a sentence of life with no possibility of parole.

Prosecutors argue the teenager acknowledged the shootings were premeditated, willful and deliberate and the sentences fit the crimes.

“There was no defect in the plea-taking process; thus, defendant cannot withdraw his plea,” said the prosecution. “Further, defendant testified under oath that he intended to kill; that he acted knowingly; and that his murders were done with premeditation, were willful, and were deliberate…”

Ethan Crumbley, who was 15 years old at the time of the shootings, pleaded guilty two years ago to murdering four students and injuring seven other people. His defense attorneys argue life without parole is too harsh a sentence, citing a troubled home life and the possibility that fetal alcohol syndrome could be a mitigating factor.

Oakland County Circuit Judge Kwame Rowe is now considering the request. There is no specific timeline for a ruling.

Nearly three years after a teenager killed four of his classmates in a shooting at Oxford High School, victims’ families are still looking for answers.

They want a review of how school officials acted leading up to the shooting, calling on Michigan’s Attorney General, Dana Nessel, to do so this week.

Steve St. Juliana’s daughter, Hana, was among those killed in the Oxford High School attack. He says further action is needed to prevent future school shootings.

“This is about getting the truth out there,” says St. Juliana, “to create the counter measures to save our kids. This is not about identifying people to prosecute.”

The families are frustrated that a state review of procedures around the 2021 shooting has not taken place. They say they’ve had a hard time getting answers from the Oakland County prosecutor and state attorney general — accusing Nessel of retracting an offer to investigate over lack of probable cause.

Speaking to the media, Nessel countered that her offer to review has always been on the table.

“Now these offers were made to the school board and to the criminal investigation and prosecutions being handled by the Oakland County Sheriff’s Office and prosecutor. Our involvement on both fronts was soundly rejected,” she said.

While Nessel says she remains willing to help, she isn’t sure why Oakland County officials are now pointing the case at her.

“My authorities are not expansive beyond those that are already held by the county prosecutor and sheriff, who currently have the investigation, and have investigated this matter thoroughly for years and years now,” she said.

Nessel says her office can’t investigate without a referral from local authorities. She says she’s confused by Oakland County Sheriff Mike Bouchard appearing in support of the Oxford family’s call to action, arguing that she’d need information from him to move forward.

In a statement, Oakland County Prosecutor Karen McDonald said she’s unaware of any action needed by her office to involve the attorney general.

Oxford families say they’re tired of the finger pointing.
