James Crumbley Declines to Testify in His Michigan School Shooting Trial

Testimony ended Wednesday morning in the trial of James Crumbley, whose son carried out Michigan’s deadliest school shooting more than two years ago, and whose wife was convicted last month in the same courtroom for failing to prevent the rampage.

Prosecutors took the rare step of seeking to hold the Crumbleys partially responsible for the shooting at Oxford High School on Nov. 30, 2021, in which their son, Ethan, who was 15 at the time, killed four people and injured seven others.

“That nightmare was preventable, and it was foreseeable,” Marc Keast, an Oakland County prosecutor, said in an opening statement last week. He accused Mr. Crumbley of failing to secure the gun that his son used in the shooting.

Mr. Crumbley has been jailed since December 2021, when he and his wife, Jennifer Crumbley, were each charged with four counts of involuntary manslaughter. They requested separate trials, and unlike his wife, Mr. Crumbley chose not to testify in his own defense.

The witness lists in the two trials were similar, but there were a few key differences in the evidence that was presented.

At Ms. Crumbley’s trial, lawyers pored over her communications with her son, including months of text messages, as prosecutors tried to paint her as a detached and negligent mother.
