MACKINAC ISLAND, Mich. (AP) – The Michigan appeals court says a jury should decide whether a snowmobile maker is responsible for the deaths of two sisters who plunged off a cliff on Mackinac Island.

Karen Schwarck and Edith Bonno died in 2010 when their snowmobile went into reverse and over the West Bluff.
