U.S. Senator Bob Casey is urging the Consumer Products Safety Commission to get to the bottom of a deadly house fire in Harrisburg. Casey sent an open letter to the commission this week asking for a determination as to whether a hover board caused the blaze. The Harrisburg Bureau of Fire claims the toy started the flames that killed two-year-old Ashanti Hughes last weekend but the commission has not yet reached a conclusion. Casey is also asking the commission to "Work with hover board manufacturers to increase recall compliance and educate consumers about the fire risk."
