A prosecutor has charged the parents of a 15-year-old boy who is accused of killing four students and wounding others in a shooting at a Michigan high school this week.
James and Jennifer Crumbley face involuntary manslaughter counts after Tuesday's mass shooting in Oxford Township, about 50km north of Detroit. Here is a timeline of events before the rampage and what has happened since:
Friday, November 26: James Crumbley buys a 9mm Sig Sauer from Acme Shooting Goods in Oxford, according to Oakland County Prosecutor Karen McDonald. His 15-year-old son Ethan later posts a photo on Instagram of himself holding the semi-automatic handgun, writing: "Just got my new beauty today. SIG SAUER 9mm. Any questions I will answer." He includes an emoji of a smiling face with heart eyes.

Saturday, November 27: Jennifer Crumbley, Ethan's mother, writes on social media that it is a "mom and son day testing out his new Christmas present", the prosecutor says.
