The parents of a teen injured during the mass shooting at Oxford High School in Michigan last year are suing the dealer that sold the handgun used to kill four students and injure seven others.
The Oxford Community School District and school officials are also named in the lawsuit. Mary and Matthew Mueller, the parents of the injured child, say the school district and its employees failed to address serious concerns about the shooter, Ethan Crumbley. More than a dozen students have already filed a similar federal lawsuit against the school district and some of the high school's employees.
