HARRISBURG, Pa. (AP) — The families of two girls killed in a Pennsylvania fire that was blamed on a hoverboard have filed a lawsuit against the distributors of the device. The lawsuit filed last month comes a little more than a year after the U.S. Consumer Product Safety Commission announced a LayZ Board sparked the fire that killed 2-year-old Ashanti Hughes and 10-year-old Savannah Dominick at their Harrisburg home in March 2017. The lawsuit says that the importers and distributors of the hoverboard were negligent for continuing to market the device even though it posed a risk of overheating and igniting.
