ST. PAUL, Minn. - Family members of a Minnesota man fatally shot by a police officer in a traffic stop in July says they are pleased that the officer has been charged with manslaughter.

Valerie Castile is the mother of Philando Castile, a black man who was 32 when he was shot after his car was pulled over in a St. Paul suburb.

Castile says the charge against officer Jeronimo Yanez is the strongest the family could have hoped for under Minnesota law. A prosecutor said Wednesday in filing the charge that Yanez wasn't justified in using deadly force.

Glenda Hatchett, an attorney for the family, called the charge "an important signal to this nation."
