MILWAUKEE -- Member's of Milwaukee's black community join the Stingley family in calling for criminal charges to be filed for the death of 16-year-old Corey Stingley.

A large group has gathered in front of the Milwaukee County District Attorney's Office to protest Miwaukee County District Attorney John Chisholm after be decided not to press charges in this case. They are calling for Chisholm to be fired or at the very least not be re-elected. 

Stingley died after three adult men pinned him to the floor after a shoplifting attempt at a West Allis convenience store.

The Medical Examiner's Office ruled Stingley's death a homicide, and while the medical definition varies from the criminal definition of the word, family members say some type of criminal charges are warranted in the matter.

The report said Stingley died due to lack of oxygen to the brain during a violent struggle with multiple individuals.

A federal investigation into the case in underway.
