The parents of the teen who killed four students last year at Oxford High School argued in court Friday against using experts on mass shootings in their upcoming trial.
Prosecutors charged Jennifer and James Crumbley with involuntary manslaughter accusing them of being grossly negligent by ignoring signs their son could become violent.
They are set to go on trial next year.
In court filings, prosecutors wrote that the Crumbleys created a “pathway to violence” for their son Ethan, who pleaded guilty earlier this week to shooting four classmates to death and wounding seven other people at Oxford High.
Defense attorneys countered that the court should not allow experts on mass shooting to testify at the parents’ trial, claiming that the idea of creating a “pathway” to killing is a fairly new area of research with in-consistent findings.
