Man drives through barricade near Michigan church day after shooting

A man in a red car drove through a barricade near where a gunman a day earlier rammed his pickup truck into a church, opened fire on congregants and then set the church ablaze. At least four people were killed and eight others wounded in the attack during a Sunday morning service.
