Parents of Michigan boy charged in Oxford school shooting

The parents of a teen accused of killing four students at a Michigan high school have been charged with involuntary manslaughter.

A prosecutor described chilling moments that day when a teacher found a drawing of a gun, a person bleeding and the words ``help me'' at the boy's desk.

Prosecutor Karen McDonald says Jennifer and James Crumbley committed ``egregious'' acts, from buying the gun for Ethan Crumbley and failing to intervene when they were summoned to the school and confronted with the drawing.

Police say he returned to class and later emerged from a bathroom with a gun, firing at students in the hallway.
