What was Jennifer Crumbley charged with?

Jennifer Crumbley was charged with four counts of involuntary manslaughter, one count for each student killed by her son at Oxford High School on Nov. 30, 2021. 

Her husband, James Crumbley, is also facing the same charges and is expected to go to trial on March 5, 2024.

What did Jennifer Crumbley do?

The prosecution argued that Jennifer and James ignored their son's mental health and even bought him a gun before the Oxford High School shooting. 

Jennifer's attorney maintained that her client knew nothing about guns and was not involved in purchasing the weapon. Receipts provided in court show that James bought the gun, and the shooter admitted during his plea hearing that he gave James money to buy the firearm. Video from a gun range showed Jennifer shooting a gun with her son, but her lawyer claims she didn't know what she was doing.

Journal entries detailing the shooter's mental state have been presented in court, but Jennifer's defense argues that there is no evidence Jennifer knew about this writing.

Witnesses called by the prosecution during the trial have also described a meeting between the Crumbley parents and school officials the morning of the shooting. The parents were called after violent drawings were discovered on their son's schoolwork. 

During this meeting, a school counselor told the parents to get their son mental health help as soon as possible and recommended that they take him home from school. However, the parents chose not to take him home.
