A judge in the US state of Michigan began a preliminary hearing on Tuesday to decide whether prosecutors have enough evidence to try on involuntary manslaughter charges the parents of a teenager accused of killing four students at his high school.
James and Jennifer Crumbley, who have pleaded not guilty, are accused of buying their 15-year-old son Ethan the gun he used to carry out the November 30 attack, and of ignoring signs Ethan was having violent thoughts as late as the day of the shooting.
