KANSAS CITY, Mo. (AP) – The family of a Missouri man fatally beaten in 2013 outside of Arrowhead Stadium, home of the Kansas City Chiefs, is suing the NFL franchise. The Kansas City Star reports the wrongful-death lawsuit was filed Monday in Jackson County on behalf of Kyle Van Winkle’s widow and his son, who was just weeks old when Van Winkle died.

Seeking unspecified damages, the lawsuit blames a lack of adequate security in the parking lot at the time Van Winkle was beaten during an altercation. The law firm behind the lawsuit says the lawsuit’s goal is to make Arrowhead safer for fans. The Chiefs have declined to comment.  Joshua Bradley of Independence has pleaded guilty to involuntary manslaughter in Van Winkle’s death and is serving five years of probation.
