The father of a 15-year-old Michigan school gunman who killed four students has been convicted of manslaughter.
The trial heard that James Crumbley, 47, had ignored his son Ethan's mental health needs, buying him the handgun he used in the November 2021 attack.
He and his wife - who was convicted on the same charges - now both face a maximum of 15 years in prison.
The case is thought to mark the first time the parents of a mass shooter have been held criminally liable.
