KANSAS CITY, Mo. (AP)- A Missouri judge has dismissed an involuntary manslaughter charge against a woman accused of providing alcohol to a teenager who was later involved in a fatal traffic accident.

Jackson County prosecutors were trying to overcome laws and court decisions protecting people who serve alcohol in social settings from being charged for harm done by drunken guests.

The Kansas City Star reports the judge noted those precedents in her ruling Friday. The judge said Missouri law specifically states that consuming alcohol, not furnishing it, is the cause of injuries inflicted by a drunken driver.

Prosecutors alleged the woman supplied liquor at a party in 2009 and knew the 19-year-old was drunk when he left her Kansas City home. He was later involved in a crash that killed a 16-year-old girl.
