Exactly one year ago Wednesday, then-15-year-old Ethan Crumbley opened fire on his Oxford, Michigan, high school, killing four innocent students and injuring seven others.

On Tuesday, the Michigan Supreme Court temporarily halted the case against Crumbley's parents, James and Jennifer Crumbley, who are charged with four counts of involuntary manslaughter each for their alleged roles in Ethan's crimes.

"[W]e REMAND this case to the Court of Appeals for consideration as on leave granted, limited to whether there was sufficient evidence of causation to bind the defendant over for trial on the charges of involuntary manslaughter," the Tuesday order states.

Justice Richard Bernstein dissented, stating that while the parents' case "raises a number of novel legal issues, the appellate process is designed" so that those issues are "considered after trial."

"Moreover, addressing causation at this stage will unnecessarily delay the trial proceedings, which are set to begin in January," the justice wrote in his dissent. "In order to avoid needless delay, I would prefer to remand to the Court of Appeals simply for that court to reconsider defendant’s challenge to the denial of the motion to quash in light of the concern articulated in Yost, as I believe any substantive questions pertaining to causation should not be addressed until after trial is complete."

James and Jennifer Crumbely, however, still face four counts of involuntary manslaughter each for their roles in their son's spiral and ultimate decision to open fire on his classmates. Prosecutors say his father purchased the then-15-year-old a gun for Christmas, and his mother posted about the gift on Facebook.
