A jury has found a Michigan mother guilty of involuntary manslaughter for failing to stop her son from carrying out a deadly school shooting.
Jennifer Crumbley, 45, is the first US parent convicted of manslaughter over a mass shooting carried out by their child.
Prosecutors accused her of being negligent in allowing her son to have a gun, and ignoring warnings signs.
Her husband, James, is facing a separate trial on the same charges.
He has pleaded not guilty.
Their son, now 17, is serving life in prison for killing four classmates at Oxford High School in Michigan on 30 November 2021.
Seven people were also injured in the shooting.
The judge, speaking to jurors, said this was likely "the hardest thing you've ever done".
