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

They want a review of how school officials acted before the shooting, asking Michigan Attorney General Dana Nessel to do so this week.

Daughter of Steve St. Juliana, Hana, was among those killed in the Oxford High School attack. He says additional measures are needed to prevent future school shootings.

“It’s about finding out the truth,” says St. Juliana, “to create countermeasures to save our children. It’s not about identifying people to prosecute.”

The families are frustrated that there hasn’t been a state review of the procedures surrounding the 2021 shooting. They say they’ve had a hard time getting answers from the Oakland County district attorney and the state attorney general — accusing Nessel that he withdrew an offer to investigate for lack of probable cause.

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

“These offers have now been made to the school board and the investigation and prosecution handled by the Sheriff’s Office and the Oakland County District Attorney. Our involvement on both fronts has been completely rejected,” she said.

While Nessel says she remains willing to help, she’s not sure why Oakland County officials are now targeting her case.

“My authorities are not extended beyond what is already held by the county attorney and the sheriff, who currently have the investigation and have been investigating this matter thoroughly for years and years,” she said.

Nessel says her office cannot investigate without a referral from local authorities. She says she is confused that Oakland County Sheriff Mike Bouchard has come out in support of the Oxford family’s call for action, arguing she would need information from him to move forward.

In a statement, Oakland County District Attorney Karen McDonald said she was not aware of any action required by her office to involve the attorney general.

Oxford families say they are tired of the finger-pointing.
