Michigan authorities are asking the public to be on the lookout for the parents of Oakland High School shooting suspect Ethan Crumbley.

A statewide "Be on the Lookout" (BOLO) alert was issued for James and Jennifer Crumbley Friday, two police departments confirmed to FOX 2 Detroit.

The two parents are each facing four counts of involuntary manslaughter after their 15-year-old son was accused of killing four students after opening fire inside Oakland High School earlier this week., according to Oakland County prosecutor Karen McDonald.
