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.

Stephen J Morse, a professor of law and psychiatry at the University of Pennsylvania, said he disagreed with the verdict, arguing that because Ethan Crumbley had pleaded guilty, he was the only one responsible for the shooting.

"I understand that she was not necessarily the best mother in the world, but this is not a crime," he said.

Mr Morse said he believed the decision could set a bad precedent, causing courts to look for "scapegoats" in similar situations.
