Parents of the victims of a Michigan mass shooting were steadfast observers at court hearings that led to three separate convictions of an entire family. One of their goals now is to see more change rise out of the 2021 tragedy at Oxford High School, The Associated Press reported.

“We can put people on the moon. We can build skyscrapers, huge monuments like the Hoover Dam — and we can’t keep our kids safe in schools,” said Steve St. Juliana, whose 14-year-old daughter, Hana, was killed by Ethan Crumbley.

“I think people just need to wake up and take action. Stop accepting the excuses. Stop buying the rhetoric,” St. Juliana said last week after the teen shooter’s father was convicted of involuntary manslaughter.

James Crumbley, 47, was found guilty, five weeks after his wife, Jennifer Crumbley, 45, was convicted of the same charges at a separate trial in suburban Detroit. They were accused of failing to take critical steps, including safely securing a gun at home, that could have prevented their son’s attack.

“Basic, reasonable, ordinary care” by the parents could have prevented the shooting, but instead the community has been devastated, said prosecutor Karen McDonald.

Nicole Beausoleil, the mother of slain 17-year-old Madisyn Baldwin, said the focus now should shift to the Oxford school district — “the school and its failures, the things that they don’t want to admit to.”

“We will be here fighting every second for our children, because they are not allowed to forget any of them,” she said.

We believe the result of these hearings was the appropriate measure, given the facts of the case.

James Crumbley decided not to testify in his trial, unlike his wife, whose time in the witness chair didn’t help her. Jennifer Crumbley told a jury that she wouldn’t have done anything differently and believed that she, too, was a victim.

How she could utter that in front of a room filled with people who had loved ones violently taken away from them is beyond us. Hopefully, the April 9 sentencing of James and Jennifer Crumbley provides the victims’ families with at least some sense of justice after all they have endured.
