Michigan school shooting: prosecutor explains rare terrorism charge

Parents may also be charged in another unusual move for failing to secure the handgun their son used

A prosecutor in Michigan has explained why the teenage suspect in a deadly high school shooting this week was unusually charged with the crime of terrorism, along four first-degree murder counts and numerous other offenses.

Charges are also being considered against the shooter's parents, prosecutor Karen McDonald said, which would be a rare move in cases of school shootings and would probably be linked to access to firearms.
