In the federal lawsuit, the family claimed East Pittsburgh failed to "properly train" its officers, resulting in the 17-year-old's death.
Rose was fatally shot at a traffic stop by officer Michael Rosfeld on June 19. Rose and another passenger were attempting to flee on foot when the teen was shot.Rosfeld, who is also named as a defendant in the suit, said he thought the car was connected to a recent drive-by shooting when he pulled it over, according to investigators. Witnesses and video captured by bystanders show Rose was unarmed at the time, sparking protests against alleged police brutality.
The suit, filed on behalf of Rose's parents, Michelle Kenney and Antwon Rose, Sr., names Rosfeld, East Pittsburgh Police Chief Lori Fruncek and Mayor Louis Payne as defendants, court documents show.
The defendants "had a duty, but failed to implement and/or enforce policies, practices and procedures for the EPPD that respected Antwon M. Rose, II's constitutional rights to assistance and protection," the suit said.
