Lawsuit alleges Ethan Crumbley brought severed bird head to school before deadly shooting

A civil lawsuit filed against Oxford Community School District this week accuses administrators of putting students in danger by allegedly downplaying the actions of the accused gunman before a shooting that left four students dead and seven others injured. 

Ethan Crumbley, the 15-year-old suspect, posted "countdowns and threats of bodily harm," the lawsuit alleged. The complaint claims the teen left "a severed bird head in a mason jar containing a yellow liquid" in a school bathroom. 

The school then emailed students and parents that "there has been no threat to our building nor our students," the lawsuit said.
